OpenAI: o1
Analysis Summary
OpenAI: o1 is OpenAIās entry in the o1 line-up. It was released in December 2024. On our leaderboard it earns Professional-tier status, ranking #10 of 565 models in our overall business-suitability ranking. For raw reasoning ability it ranks #107 of 374, putting it in the upper half for overall intelligence.
On coding it ranks #139 of 311, a reasonable fit for everyday development support. It also ranks #118 of 286 for agentic, multi-step tasks ā the autonomous, tool-driven workflows that underpin business automation. Its 200K-token context window is larger than 66% of the models we list, suiting long documents, large codebases, and retrieval-heavy workloads. Crucially for business adoption, OpenAI: o1 combines tool use, function calling, vision input, and step-by-step reasoning in a single model, letting teams consolidate several use cases instead of stitching together multiple services.
At $15.00 input and $60.00 output per 1M tokens, OpenAI: o1 is among the most expensive options we list, so it is best reserved for high-value work where answer quality matters more than per-token cost. OpenAI: o1 is a dependable pick for businesses that need strong, well-rounded performance without paying frontier prices.
Editorial notes
OpenAI o1 delivers strong reasoning, vision, file input, and tool use with a 200K context window, scoring well on GPQA and MMLU Pro, though its premium pricing and older generation place it behind current flagship models.
