The model carries a 200k context window, 100k max output, and pricing of $150 per 1M input tokens and $600 per 1M output tokens, and is also referenced as o1-pro and openai/o1-pro. The deprecation gives teams roughly a year to find and migrate code calling o1-pro before it stops serving requests.", "body_md": "OA▲ Retiring soon\n\n# OpenAI o1-pro\n\nOpenAI · o1-pro-2025-03-19\n\no-seriestext+vision200k context100k max out$150 / $600 per 1M\n\nalso matches: \n\n`o1-pro-2025-03-19`` o1-pro``openai/o1-pro`\n[provider announcement →](https://developers.openai.com/api/docs/deprecations)\n\nDoes your code call OpenAI o1-pro?\n\n$ curl -fsSL https://llmstatus.ai/install.sh | bash\n\nThen `mm status` in any repo — it finds every model you use and flags the ones on a clock.
