OpenAI: o1

OpenAI o1 is a reasoning-focused model from OpenAI that accepts text, images, and files as input and supports tool use. Its 200,000-token context window and 100,000-token output ceiling make it suitable for long-document work and tasks requiring extended generation. Structured output support is not confirmed in available data. At $15.00 per million input tokens and $60.00 per million output tokens, this is an expensive option, and the cost of reasoning-heavy tasks will push output costs up quickly. Its blended benchmark score of 56.4 covers only three benchmarks, so its standing across broader use cases is not well established. Teams that specifically need built-in reasoning on multimodal inputs and can absorb premium pricing may have reason to shortlist it, but buyers seeking either budget efficiency or broad, independently verified performance data should compare alternatives carefully before committing.
