OpenAI: GPT-5.4 Pro
openai/gpt-5.4-pro
Our take
AI-assisted analysis based on the sources below. Suitability is an editorial assessment; test it on your own workload.
OpenRouter's catalog presents openai/gpt-5.4-pro as OpenAI's GPT-5.4 Pro variant for complex, high-stakes work. It reports text, image, and file inputs with text output, a context window of roughly one million tokens, always-on reasoning with a medium default and higher effort options, plus tool use, structured outputs, and response controls. These are catalog-reported capabilities, not measured results: the supplied source contains no benchmark data, and no independent model card was available in this source pack.[1]
Strengths
- The catalog reports multimodal inputs from text, images, and files, with text-only output.[1]
- It reports a context window of roughly one million tokens, which may accommodate very large inputs.[1]
- It lists mandatory reasoning with medium, high, and xhigh effort settings, plus tools and structured outputs.[1]
Limitations
- Evidence is limited to OpenRouter's catalog; an independent model card was not available in this source pack.[1]
- No benchmark measurements, knowledge cutoff, or safety evaluation are supplied, so real workload validation remains necessary.[1]
- Reasoning is mandatory, and the catalog does not report a mode without reasoning.[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 |
| Document analysis | No measurement | input: file |
| Vision | No measurement | input: image |
| Image generation | No measurement | — |

No evaluations are supplied for this model.
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
