Benchmark leaderboards featuring GPT-5.4 Pro
All leaderboardsGPT-5.4 Pro: common questions
How much does GPT-5.4 Pro cost per 1M tokens?
GPT-5.4 Pro is listed at $30.00 per 1M input tokens and $180 per 1M output tokens as of 22 September 2026; the lowest output price among 2 providers is $90.00 on OpenAI. Prices come from the OpenRouter catalogue and re-observe on every refresh. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $150 total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.
What is the context window of GPT-5.4 Pro?
GPT-5.4 Pro has a published context window of 1M tokens (1,050,000) and a maximum output of 128K tokens. Individual providers can serve less than the published maximum; the providers table lists each endpoint's own limit.
Is GPT-5.4 Pro open-weight?
API only. No downloadable model weights are linked in the current source data; access is through a hosted API or product.
Which API providers serve GPT-5.4 Pro?
2 providers serve GPT-5.4 Pro through OpenRouter as of 22 September 2026: OpenAI and Azure. Each provider's price, context limit, quantization and measured uptime are in the providers table above.
Which benchmarks has GPT-5.4 Pro been evaluated on?
GPT-5.4 Pro has published results on 1 public board tracked by ModelCap as of 22 September 2026: ARC-AGI-2 83.3% (#24 of 214). Each board page ranks every tracked model on that benchmark; the ModelCap Index combines them with published uncertainty.
When was GPT-5.4 Pro released?
GPT-5.4 Pro first appeared in the catalogue on 5 Mar 2026. It has since been superseded by GPT-5.5 Pro. Rank and price movements since then are recorded on the site's changes feed.
