This model is deprecated. We still benchmark its performance, but less often: every 18 hours instead of every 6.
OpenAI has launched a newer release, o4-mini. We suggest considering it instead.

Metrics are compared against models of the same class:
- Non-reasoning models → compared only with other non-reasoning models
- Reasoning models → compared across both reasoning and non-reasoning
- Open weights models → compared only with other open weights models of the same size class:
- Tiny: ≤4B parameters
- Small: 4B–40B parameters
- Medium: 40B–150B parameters
- Large: >150B parameters
- Proprietary models → compared across proprietary and open weights models of the same price range, using a blended 3:1 input/output price ratio:
- <$0.15 per 1M tokens
- $0.15–$1 per 1M tokens
- >$1 per 1M tokens

Frequently Asked Questions
Common questions about o1-mini
o1-mini was released on September 12, 2024.
o1-mini was created by OpenAI.
Yes, o1-mini is a reasoning model. It uses extended thinking or chain-of-thought reasoning to work through complex problems before providing an answer.
o1-mini supports text input.
o1-mini supports text output.
No, o1-mini does not support image input. It can only process text.
No, o1-mini is not multimodal. It only supports text input.
o1-mini has a context window of 128k tokens. This determines how much text and conversation history the model can process in a single request.
No, o1-mini is proprietary. The model weights are not publicly available.
o1-mini is a proprietary model and OpenAI has not disclosed the model size or parameter count.
o1-mini has a knowledge cutoff of October 2023. The model's training data includes information up to this date.
