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

o1 is below average in intelligence and particularly expensive when comparing to other models of similar price. It's also faster than average, however somewhat verbose. The model supports text and image input, and has a 200k tokens context window with knowledge up to October 2023.
o1 scores 31 on the Artificial Analysis Intelligence Index, placing it below average among comparable models (averaging 31). When evaluating the Intelligence Index, it generated 35M tokens, which is somewhat verbose in comparison to the average of 13M.
Pricing for o1 is $15.00 per 1M input tokens (expensive, average: $1.50) and $60.00 per 1M output tokens (expensive, average: $10.00). In total, it cost $3270.36 to evaluate o1 on the Intelligence Index.
At 100 tokens per second, o1 is faster than average (65).

When evaluated on the Intelligence Index, o1 generated 35M output tokens, which is somewhat higher than average compared to other reasoning models in a similar price tier (median: 13M).
Yes, o1 is a reasoning model. It uses extended thinking or chain-of-thought reasoning to work through complex problems before providing an answer.
o1 supports text and image input.
o1 supports text only output.
Yes, o1 supports image input and can analyze, describe, and answer questions about images.
Yes, o1 is multimodal. It can process text and image input and generate text only output.
o1 has a context window of 200k tokens. This determines how much text and conversation history the model can process in a single request.
No, o1 is proprietary. The model weights are not publicly available.
o1 is a proprietary model and OpenAI has not disclosed the model size or parameter count.
o1 achieves a score of 31 on the Artificial Analysis Intelligence Index. This composite benchmark evaluates models across reasoning, knowledge, mathematics, and coding.
