Our take
AI-assisted analysis based on the sources below. Suitability is an editorial assessment; test it on your own workload.
OpenAI GPT-5.2 Pro (openai/gpt-5.2-pro) is described in the OpenRouter catalog as OpenAI’s most advanced model, with reported gains over GPT-5 Pro for agentic coding and long-context work. The catalog lists text, image, and file inputs; text output; a 400,000-token context; mandatory reasoning at xhigh, high, or medium effort; and tool/structured-output controls. These are catalog-reported capabilities, not measured results. The supplied pack contains no independent model card or benchmark data, so workload validation remains necessary.[1]
Strengths
- Accepts text, image, and file inputs and returns text, with a listed 400,000-token context.[1]
- Reasoning is always enabled, with xhigh, high, and medium effort settings.[1]
- API options include tools, tool choice, structured outputs, response format, seed, max tokens, verbosity, and reasoning controls.[1]
Limitations
- Only OpenRouter catalog evidence was supplied; an independent model card was not available in this source pack.[1]
- The pack provides no benchmark measurements; the catalog’s benchmark fields are empty or null, so performance remains unverified here.[1]
- Knowledge cutoff is not reported, output is text-only, and no lower or disabled reasoning effort is listed.[1]
Where to use it
- Potentially suitable for agentic coding workflows, if testing confirms the catalog’s claimed improvement.[1]
- May fit long-document or mixed text, image, and file analysis where text-only output is acceptable.[1]
- Could support complex step-by-step tasks that benefit from configurable high-effort reasoning and tool use.[1]

Tasks and capabilities
A grade appears only where the source supplies a matching measurement for that task, the model is active and the cohort holds at least 10 comparable models. The capability column lists facts the source declares — supported formats, reasoning and tool parameters — which are not measured quality.
| Task | Grade | Source-declared capability |
|---|---|---|
| General quality | No measurement | reasoning: mandatory · default medium · efforts: xhigh, high, medium · parameters: include_reasoning, reasoning, reasoning_effort |
| Coding | No measurement | — |
| Agents | No measurement | parameters: structured_outputs, tool_choice, tools |
| Writing | No measurement | output: text |
| Reasoning | No measurement | reasoning: mandatory · default medium · efforts: xhigh, high, medium · parameters: include_reasoning, reasoning, reasoning_effort |

How grades work
Each letter grade compares a model only against other models scored by the same source and metric in the current snapshot. S means the top 10%, A the next 20%, B the next 30%, C the rest. Models without a published measurement are shown as not rated — a supported format alone never implies measured quality.
- S — S — top 10% of the cohort
- A — A — next 20% of the cohort
- B — B — next 30% of the cohort
- C — C — below the B band
