A benchmark result can be relevant, repeatable and still be the wrong evidence for a buying decision. SWE-bench, Terminal-Bench and OSWorld cover different kinds of work. A strong result in one does not establish that a model will perform well in another, nor does it predict the outcome of an enterprise workflow without further evaluation.
This roundup compares the three benchmarks by the decisions they can inform, the evidence they leave out and the conditions necessary for a fair comparison. It is intended for teams deciding whether a model is worth testing, which claims to investigate and what to measure before deployment. It is not a ranking of models: no scores are presented because a score without a specific benchmark version, harness and task context is an unreliable basis for procurement.
The assessment is current as of September 30, 2026. For context on how benchmark results fit into broader model-release decisions, see Benchmarks That Actually Matter for New Model Releases. The focus here is narrower: matching a benchmark’s task domain and version to the work your organization may buy a model to perform.
How the three benchmarks were selected for comparison
The selection criterion is practical relevance, not a claim that these are the only useful benchmarks. Together, the three represent software issue resolution, terminal-based tasks and interaction with computer interfaces. Those domains often appear in enterprise agent proposals, but they demand different actions and expose different failure modes. Comparing them helps a buyer ask a more precise first question: which kind of work is this result evidence about?
A benchmark is useful when its tasks resemble an important part of the target workflow and its evaluation conditions are clear enough to interpret. “Resemble” does not mean identical. A benchmark may test a narrow action that forms one stage of a larger business process. That can still be informative if the buyer avoids treating success at that stage as proof of end-to-end completion.
Version identification is part of the selection criterion, not a footnote. A result should be tied to a named dataset or release, its evaluation harness and the model configuration used to produce it. If a report does not make these details clear, the right response is to lower confidence in the comparison, not to infer that different reports used equivalent conditions.
The table provides a first-pass map. It is not a scorecard: there are no comparable scores or universal weights to apply. The “best fit” column describes the buying question each benchmark is more naturally suited to inform, rather than promising predictive accuracy for a particular organization.
| Benchmark | Best fit for an initial buying question | Main boundary to keep in view | Useful evidence to request |
|---|---|---|---|
| SWE-bench | Can the model help resolve software issues? | A benchmark task is not the same thing as your engineering process or production change controls. | Exact dataset/version, harness and task-level outcome definitions. |
| Terminal-Bench | Can the model complete terminal-oriented tasks? | A terminal task result does not by itself establish dependable use of your shell, tools or operational environment. | Exact version, task scope, execution conditions and failure handling. |
| OSWorld | Can the model interact with computer interfaces to complete tasks? | Its benchmark environment differs from live enterprise applications. | Exact version and environment, interaction conditions and task completion criteria. |
These distinctions are more useful than a single “agent capability” label. If a vendor claim spans several work types, treat each type as a separate hypothesis. A model might be a sensible candidate for one stage while remaining an unproven choice for another. That is a reason to narrow the evaluation, not to average unlike results into a blended impression.

1. SWE-bench: evidence about software issue resolution
SWE-bench evaluates software issue resolution; comparisons require identifying the dataset or version and the evaluation harness used. Primary source.
That scope makes it a relevant starting point when the proposed use case involves interpreting a software issue and producing a change intended to address it. It can help a buyer determine whether a model is worth considering for software-maintenance work. The result is most useful when the team’s question is similarly bounded: can the candidate make progress on issue-resolution tasks under the stated evaluation conditions?
The practical advantage is focus. Software maintenance is not a single action: it may involve understanding an issue, finding relevant code, changing files, checking behavior and communicating what changed. A task-oriented benchmark result can be a reason to examine this class of work instead of relying only on general-purpose claims about coding. It gives engineering leaders a concrete domain to investigate and a basis for asking vendors what their score includes.
The corresponding limitation is that a benchmark result cannot stand in for the organization’s engineering system. A company may rely on a particular repository structure, test suite, internal conventions, review practice or release process. Unless those conditions are part of the reported evaluation, the result does not establish that the model can navigate them or produce an acceptable change under them. A task labelled “resolved” is not automatically evidence of maintainability, reviewer satisfaction or safe deployment in a particular company.
For a fair comparison, request the exact dataset or version and harness before comparing scores. Then ask what counts as success, what was held constant and how incomplete or incorrect changes are recorded. If two reports use different conditions, describe them as separate pieces of evidence rather than putting their scores in a single ranking. A numerical difference may reflect more than a model change; without comparable conditions, it cannot support a clean buying conclusion.
Pros: The domain is directly relevant to teams evaluating software issue-resolution assistance. The task focus can help turn a broad coding claim into a specific question for a technical evaluation. It is also a useful prompt to inspect the gap between a model’s benchmark task and the organization’s real maintenance workflow.
Cons: The result does not, on its own, establish fit with a company’s repositories, development conventions, review requirements or release process. Comparisons become difficult to interpret if the dataset or harness is unspecified or differs between reports. It should not be treated as evidence that an agent can autonomously own production changes.
Pricing: No benchmark price or model price is stated here. A benchmark result is not a commercial offer. Buyers should compare the relevant deployment and evaluation terms separately, using a defined workload and their own procurement process rather than inferring costs from a score.
For an engineering leader, the buying implication is straightforward: use SWE-bench to decide whether software issue resolution merits a closer test, then define a representative internal task set before estimating operational usefulness. Keep the evaluation boundary explicit. For example, if the business question is whether a model can prepare a candidate patch for review, do not quietly broaden the success claim to “the model can maintain our application.” Those are materially different conclusions.
2. Terminal-Bench: evidence about terminal-oriented tasks
Terminal-Bench evaluates terminal tasks. When quoting a result, identify the exact benchmark version; this comparison does not require or present scores. Primary source.
This benchmark is relevant when the buying question concerns work performed through a terminal rather than only generating text about a command. That distinction matters to teams considering agents for developer operations, technical support workflows or other tasks in which a sequence of command-line actions forms part of the work. The benchmark can help identify whether a terminal-task claim deserves more investigation; it cannot certify the behavior of an agent inside a company’s live environment.
Its chief strength as a comparison point is that it directs attention to task execution. A proposal that sounds capable in a conversation may still fail when it must make progress through a constrained sequence of actions. Terminal-oriented evaluation puts the discussion closer to operational work: what task was attempted, what constitutes completion, and what happens when the first approach does not work? That framing is useful even before a buyer has selected a particular model.
The boundary is the difference between a benchmark task and an organization’s actual tools, inputs and consequences. A task completed in an evaluation setting is not proof that the model can safely manage a production shell, work with the company’s operational conventions or recover correctly from a failure. Nor does a benchmark-level task outcome alone tell a buyer whether the work is acceptable to a human operator. The result is evidence about the tested conditions, not a blanket statement about terminal use everywhere.
Version discipline is particularly important when teams encounter a headline score without enough context. Record the exact version, the task set and the evaluation conditions. Ask whether the outcome represents completion, whether partial progress is distinguished from success and how failed or invalid actions are treated. These are evaluation questions, not assumptions to fill in from a label. If the answers are unavailable, describe the result cautiously and do not present it internally as a directly comparable purchasing metric.
Pros: It is aligned with a recognizable category of interactive technical work. It helps buyers move beyond claims about code or command generation and ask about task completion. Its domain can be useful even when the organization’s eventual deployment is different, because it surfaces the need to test sequences of actions rather than isolated responses.
Cons: A terminal-task result does not establish fit with a company’s actual environment, operational rules or tolerance for failed actions. Results cannot be compared responsibly without an exact version and relevant evaluation details. It also cannot answer whether an end-to-end business process is dependable when terminal work is only one component of that process.
Pricing: No price is inferred from benchmark performance. A buyer considering a terminal-oriented workflow should obtain applicable commercial terms separately and assess them against a defined workload. This comparison makes no claims about model rates, usage limits or deployment options.
Use Terminal-Bench as a signal to investigate, not as a substitute for an operational trial designed around an appropriate task. A useful follow-up question is not simply “How did the model score?” but “What would the equivalent task look like for us, what constitutes an acceptable outcome, and how would a failed or incomplete run be detected?” The answers determine whether the benchmark is a meaningful screening input or merely adjacent evidence.
3. OSWorld: evidence about computer interaction
OSWorld evaluates computer interaction tasks. Its benchmark environment differs from live enterprise applications, so a result should not be treated as direct proof of performance inside a company’s applications. Primary source.
This makes OSWorld relevant for buyers assessing models proposed for work performed through graphical computer interfaces. It can help frame the question of whether computer interaction is an appropriate capability to investigate. The fact that the task involves a computer interface does not make it equivalent to every office application, internal system or business process. A buyer still has to inspect the tested environment and the task definition before judging how close it is to the intended use.
The strength of this benchmark category is that it foregrounds interaction with an interface rather than treating computer use as a writing problem. That distinction can sharpen an evaluation. A model that describes the right action may not have completed that action; a model that appears to reach a target screen may not have completed the business objective. Buyers should therefore ask what the task outcome means and how the evaluation distinguishes an attempted interaction from a successfully completed task.
The key limitation is environmental distance. Live enterprise applications can have different layouts, data, account settings, interruptions and consequences from those present in a benchmark environment. A result in the benchmark setting cannot establish how a model will cope with changes in an organization’s application or workflow. It also does not tell a buyer whether an apparently successful interaction produced the intended business result. Those questions require evidence from the actual workflow or a suitably representative evaluation.
Pros: It is a relevant screening reference when a proposed use case involves computer-interface interaction. It encourages evaluators to distinguish interface actions from ordinary text generation and to clarify what “task complete” means. It can help determine whether a model warrants further assessment for computer-use work.
Cons: Benchmark performance does not establish performance in live enterprise applications, whose environments differ. A task outcome does not automatically prove that the business objective was achieved. Buyers should not extrapolate from a benchmark environment to a company’s own applications without checking the gap and testing the critical parts of the workflow.
Pricing: There is no benchmark-derived price or commercial comparison in this roundup. Procurement should obtain applicable terms directly and consider them separately from task performance. A benchmark is evidence about a type of task under specified conditions, not a quote for the cost of operating a business process.
For a business operator, the useful question is whether the environment and task are close enough to justify a next step. If the intended work depends on navigating a particular internal system, the benchmark may indicate that the broad capability is worth evaluating, but the organization’s own application remains the decisive test. Treat differences in environment as a substantive limitation rather than a small implementation detail.
How to compare the three without creating a false ranking
These benchmarks should not be arranged as first, second and third place. Their domains differ, so a score in one does not mean the model is generally “better” than a model with a score in another. Even within a domain, scores are only meaningfully comparable when the relevant versions, evaluation conditions and success definitions are sufficiently aligned.
A comparison should begin with the business task, not the available leaderboard. Describe the work in one sentence using an observable outcome: for example, “identify the issue, prepare a candidate change and provide evidence for a reviewer,” or “complete a defined sequence of interface actions and verify the resulting record.” Then identify which parts of that task each benchmark actually addresses. If the task does not resemble the benchmark’s domain, the result may have little bearing on the decision even when the score is prominent.
Next, separate screening evidence from decision evidence. Screening evidence helps determine which candidates deserve further attention. Decision evidence is strong enough, relevant enough and sufficiently representative to inform a deployment choice. A public benchmark may be useful for screening while remaining too distant from the organization’s real process to support deployment. Being explicit about that distinction prevents a preliminary signal from being repeated as a proven operational result.
A useful related lens is task-level reliability across releases. Tool-Use Reliability Across Frontier Releases: A Benchmark Methodology examines that broader methodological question. Here, the central discipline is simpler: do not compare unrelated task domains as if they measured the same capability, and do not compare different versions without recording the difference.
| Buying decision | Most relevant starting point | What the result can help you decide | What it cannot settle alone |
|---|---|---|---|
| Whether to investigate software issue-resolution assistance | SWE-bench | Whether the domain merits a closer, version-aware evaluation. | Whether the model fits your repositories and engineering process. |
| Whether to investigate terminal-task execution | Terminal-Bench | Whether terminal-oriented task performance merits further testing. | Whether the agent can operate acceptably in your actual environment. |
| Whether to investigate interface-based computer use | OSWorld | Whether computer interaction is a plausible candidate capability to assess. | Whether your live enterprise application workflow will succeed. |
This matrix is intentionally modest. It does not suggest that one benchmark is sufficient for a purchase, nor that every organization should evaluate all three. If the intended workflow is limited to one domain, select evidence for that domain and test the gap that matters. If a proposal spans several domains, treat each as a separate part of the evaluation rather than blending them into one broad capability claim.
A hypothetical buying decision: engineering change preparation
Consider a hypothetical mid-sized software company deciding whether to evaluate an agent that could help prepare engineering changes. The company’s proposed workflow is: receive a ticket, inspect the relevant code, prepare a change, run appropriate checks and give an engineer a concise handoff. This example is illustrative; it does not describe a real PADISO project or measured result.
The team first maps the work to benchmark domains. The issue and code-change portion makes SWE-bench the closest initial reference. If the candidate must also carry out terminal actions, Terminal-Bench may provide a separate signal about that type of task. OSWorld is not the natural first benchmark for this workflow unless a meaningful part of the proposed work actually requires computer-interface interaction. Including it merely because it concerns agents would add noise, not useful coverage.
The team then writes down the decision it needs to make: should the candidate progress to an internal evaluation, not should it be deployed. It records the benchmark name, exact version or dataset, harness and reported outcome definition for each available result. Where a report does not identify a condition, the team marks it “unknown” rather than filling in a plausible assumption. This simple record can prevent a score from acquiring more authority as it is repeated across procurement and engineering discussions.
For an illustrative allocation of a two-week evaluation window, assume the team has ten engineer-days available. It might assign two days to confirming benchmark comparability and defining candidate tasks, six days to a small internal evaluation, and two days to reviewing failures and deciding the next step. Those numbers are planning assumptions only, not recommended universal allocations or cost estimates. The important design choice is reserving time for failure review instead of spending the entire window collecting successful demonstrations.
The internal tasks should reflect distinct sources of difficulty. One task might involve a clearly stated defect with a well-defined expected behavior. Another might involve incomplete issue context, where the acceptable outcome could be a request for clarification rather than a speculative change. A third might test whether the agent can report that a check failed instead of presenting the work as complete. The point is not to make a benchmark harder for its own sake; it is to expose which conditions change the business decision.
The team defines acceptance criteria before seeing results. For example, it could require that a candidate change be reviewable, that the handoff identify what was changed and what remains unverified, and that a failed check be reported accurately. These are proposed criteria for the hypothetical company, not claims about benchmark scoring. The team also decides what counts as a failed task, a partial result and an acceptable request for human input. Without those definitions, post hoc judgment can turn a weak run into a success story or a useful cautious response into a failure.
The resulting decision might be to continue testing only if the candidate’s work is both useful and inspectable. A task that appears successful but omits a known failure is not equivalent to a task that completes with a clear account of its limits. Likewise, a candidate that declines to proceed when essential information is missing may be more suitable for a supervised workflow than one that invents a confident answer. The team’s desired operating role therefore matters as much as a headline benchmark result.
This example illustrates why the benchmarks are screening inputs, not substitutes for a buying specification. SWE-bench can orient the engineering question; a terminal benchmark can inform a separate execution question; and an internal evaluation can test the company-specific steps and acceptance conditions. Each piece should retain its own meaning. A favorable signal in one layer must not be silently promoted into evidence for all the others.
A counterexample: when a relevant score still misleads
Imagine a buyer sees an impressive result on a benchmark that appears close to the intended task. The buyer selects the model, but the actual business workflow depends on a different application environment, an undocumented internal convention and a final outcome that is not visible from the benchmark task’s completion signal. The benchmark may have been measured correctly. The purchasing inference is still too broad.
The mistake is not necessarily that the benchmark is poor. It is that the buyer has moved from “the model performed well on these benchmark tasks” to “the model will deliver this business result” without evidence for the intervening assumptions. Similarity of labels—coding, terminal use or computer use—is not enough. The input, environment, acceptable actions, failure consequences and definition of completion must also be examined.
A useful counterfactual is to ask whether the same result would change the decision if the benchmark label were hidden. If the buyer cannot explain which task properties make the result relevant, the result is probably functioning as a reputation signal rather than decision evidence. Conversely, if the buyer can name the matched task properties and the remaining gaps, the benchmark may be serving a defensible screening role even when it cannot settle the purchase.
This distinction also limits the danger of selective reporting. Teams often remember a best-case score and forget the conditions attached to it. A procurement record should preserve those conditions beside the result and describe what conclusion the evidence supports. “Worth an internal trial” is a valid conclusion. It is more precise than “proven for our workflow,” and it does not diminish the value of a useful benchmark.
Failure analysis: why benchmark comparisons break down
Version drift. A team may compare a recent result with an older result because both carry the same benchmark name. If the dataset, task set or evaluation setup differs, the apparent movement may not isolate a model change. Record the version and conditions with every result. If a comparison cannot be normalized confidently, treat it as context, not a trend line.
Harness ambiguity. The harness is part of the evaluation: it determines how a task is presented and how its outcome is assessed. When a report omits the harness or leaves success criteria unclear, a buyer cannot safely assume that another report applied the same method. The failure here is interpretive. The score may be real, but the comparison is under-specified.
Domain substitution. A team may use the nearest available benchmark as a proxy for a different task because both involve an agent. That shortcut can be particularly tempting when the procurement question is broad. Instead, list the actual actions and outcomes in the proposed workflow, then mark which benchmark covers each part and which parts remain untested. A visible gap is more useful than a false claim of coverage.
Completion mistaken for business success. A benchmark’s task outcome is not automatically the organization’s desired result. A task can satisfy a narrow completion rule while missing an operational requirement that matters to the buyer. Define the business outcome separately, and verify it independently in any internal evaluation. Do not treat an agent’s own statement that it finished as evidence that the relevant change or record is correct.
Failure hidden by aggregation. A single overall result can obscure whether a candidate consistently handles a class of tasks or succeeds unevenly. Where task-level evidence is available, examine the pattern and the conditions around failure rather than relying on one summary number. This does not require a complex statistical program for every screening decision. It does require asking whether the aggregate conceals a failure mode that would change the purchase.
Evaluation conditions confused with deployment conditions. A controlled benchmark setting and a live operational setting are not interchangeable. That gap is explicit for OSWorld, whose environment differs from live enterprise applications, and it is a general reason to validate domain fit. Identify the specific difference likely to matter—such as input format, application context or completion criteria—and test that difference rather than claiming the benchmark already covers it.
These failure modes call for different remedies. Version ambiguity needs better provenance; domain mismatch needs a different or supplemental evaluation; a weak completion definition needs clearer acceptance criteria. Calling every problem “benchmark limitations” is too vague to help procurement. Name the missing evidence and decide whether it is material to the buying decision.
Reproducible decision protocol and worksheet
Use the following protocol when benchmark evidence is part of a purchase review. It is designed to leave a short, auditable record of what the team compared and what it concluded. It does not require a score, and it does not presume that a benchmark is appropriate for every proposed use.
-
State the decision in operational language. Write one sentence that names the work and the next decision. For example: “Determine whether this candidate merits an internal evaluation for preparing software changes for engineer review.” Avoid broad statements such as “assess agent intelligence.” A well-bounded decision makes it possible to distinguish relevant evidence from impressive but unrelated evidence.
-
Break the work into task stages. List the observable stages that matter, such as interpreting an issue, editing a change, carrying out a terminal task or interacting with an application. Do not add stages simply because a benchmark exists for them. Mark which stages are essential, which are optional and which require a human decision. This map exposes whether the proposed use case actually belongs to one benchmark domain or crosses several.
-
Select the closest domain, then state the mismatch. Choose SWE-bench for a software issue-resolution question, Terminal-Bench for terminal-task evidence, or OSWorld for computer-interaction evidence when that domain is genuinely relevant. Write down the most important difference between the benchmark task and the company’s intended work. A selection without a stated mismatch tends to invite overconfidence; the mismatch is a reminder of what still needs testing.
-
Capture provenance before comparing results. For each reported result, record benchmark name, exact version or dataset, harness, model identifier as stated in the report, evaluation date if available, and outcome definition. Mark unavailable details as “not stated.” Do not infer them, and do not merge results with materially different conditions into one ranking. The model identifier is included as a record field, not as an assumption about any product’s naming scheme.
-
Specify the evidence claim. Write what the result supports in one sentence, then write what it does not support. A defensible claim could be: “This result makes the candidate worth evaluating for tasks in this domain under the reported conditions.” An unsupported extension would be: “This result proves the candidate can complete our full process.” Keeping both statements together makes the boundary easy to preserve in an executive summary.
-
Define an internal check for the largest gap. Choose a small set of representative tasks that test the most decision-relevant mismatch, not merely the easiest benchmark-like examples. Define acceptable completion, partial completion, a safe stop and a failure before running the evaluation. If the task has an external consequence, specify how that consequence will be checked independently; a model’s description of its own action is not an outcome check.
-
Review failures by decision impact. For each failure, record what happened, which task condition triggered it and whether it would change the intended use. A low-impact formatting defect and an unreported incorrect result should not be summarized as equivalent misses. The purpose is not to create a polished failure taxonomy for its own sake; it is to identify which observed behavior changes the buying decision or requires a different operating boundary.
-
Write the conclusion at the right strength. Choose among conclusions such as “not relevant,” “useful screening evidence,” “progress to internal evaluation,” or “more evidence required.” Avoid a deployment recommendation based solely on a benchmark unless the organization has separately established that the benchmark’s scope and conditions answer its deployment question. The conclusion should be no broader than the evidence that supports it.
The worksheet below is designed to be copied into a procurement note or evaluation record. It is intentionally compact enough to print, but each field has a decision purpose. Completing it is more useful than collecting a larger list of scores without a clear account of what they mean.
| Field | Record |
|---|---|
| Buying decision | What specific decision will this evidence inform? |
| Intended workflow | What work and observable outcome are in scope? |
| Benchmark selected | SWE-bench, Terminal-Bench, OSWorld, or none; explain fit. |
| Exact version or dataset | Record the name as reported; mark unknown if absent. |
| Harness and conditions | Record what is known; do not infer missing details. |
| Result and outcome definition | Preserve the source’s stated terms and units. |
| Match to intended work | Which task stages are represented, and which are not? |
| Largest evidence gap | What difference could overturn the decision? |
| Internal check | What task or outcome will test that gap? |
| Decision supported | Screening, further evaluation, or another explicitly limited conclusion. |
For a quick printable summary, retain four lines at the top of the evaluation record: Decision: what choice is being made; Evidence: which exact benchmark version and conditions were considered; Gap: what important part of the intended work remains untested; Next step: what evidence would resolve that gap. If one of those lines is blank, the team may be looking at a result without yet having a decision process around it.
The protocol can be scaled to the stakes. A preliminary market scan may need only the decision, benchmark, version and evidence boundary. A purchase decision for an operational workflow calls for more careful task definition and internal checking. The principle stays constant: preserve the link between evidence and the narrow claim it can support.
Turning benchmark evidence into a procurement recommendation
A sound recommendation explains why the selected benchmark is relevant, which conditions were compared and what remains unknown. It should distinguish between technical interest and operational readiness. A model that merits further evaluation is not necessarily a model ready for deployment; a result that is not directly comparable may still be useful context, but it should not be described as a like-for-like advantage.
The recommendation should also make the alternative visible. If the benchmark domain is a poor match, say so and explain what type of evidence would be more appropriate. If the result is promising but the environment is materially different, recommend testing that gap. If key provenance details are missing, ask for them before drawing a comparative conclusion. Each outcome is a practical response to a specific evidence limitation, not a generic request for “more testing.”
Do not collapse task quality, reliability and business value into a single verdict unless the organization has defined how they relate. A benchmark can help answer whether a task capability is worth investigating. It cannot, by itself, set an acceptable operating threshold or establish that the effort is worthwhile for a particular team. For a separate discussion of how reasoning effort affects user-facing latency and cost tradeoffs, see Choosing Reasoning Effort: When More Thinking Costs More Than It Saves. That is a distinct product-design question, not something a benchmark label can settle.
Once the team has credible task evidence, routing decisions are also separate: which model should handle which work, and what evidence justifies escalation? Model Routing for Enterprise Agents: Cheap First, Escalate on Evidence covers that adjacent decision without changing what these benchmarks measure. Likewise, a company-specific task set should be sampled and held out carefully; the practical design considerations are discussed in Build a Private Agent Evaluation Set: Sampling and Holdout Design.
For leaders who need to turn these comparisons into a procurement plan, AI evaluation and strategy is an appropriate next step. The central work is to connect the intended decision to relevant evidence, make version and environment differences explicit, and identify what still needs validation. A benchmark should sharpen that process—not substitute for it.
Closing perspective
SWE-bench, Terminal-Bench and OSWorld are most useful when treated as distinct instruments for distinct task domains. SWE-bench can inform a software issue-resolution question, Terminal-Bench a terminal-task question, and OSWorld a computer-interaction question. None is a universal measure of agent quality, and none establishes that a model will deliver a company’s end-to-end business result.
For a buying decision, the disciplined path is to match the domain, record the exact version and evaluation conditions, state the narrow claim the result supports, and test the most consequential gap. That approach preserves the value of public benchmark evidence while preventing it from carrying more weight than it can bear.
