Benchmark leaderboards featuring GPT-5.2 Pro
All leaderboardsGPT-5.2 Pro: common questions
How much does GPT-5.2 Pro cost per 1M tokens?
GPT-5.2 Pro is listed at $21.00 per 1M input tokens and $168 per 1M output tokens as of 22 September 2026. 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 $126 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-5.2 Pro?
GPT-5.2 Pro has a published context window of 400K tokens (400,000) 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-5.2 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-5.2 Pro?
One provider serves GPT-5.2 Pro through OpenRouter as of 22 September 2026: OpenAI. Each provider's price, context limit, quantization and measured uptime are in the providers table above.
