Scores come from live data — output price (cost), context length, open vs closed weights (openness & self-hosting) and vision/tool support (multimodality). Raw task quality isn't scored here; it depends on your benchmark — see the verdict.
OpenAI's flagship model, GPT-4 is a large-scale multimodal language model capable of solving difficult problems with greater accuracy than previous models due to its broader general knowledge and advanced reasoning...
The latest and strongest model family from OpenAI, o1 is designed to spend more time thinking before responding. The o1 model series is trained with large-scale reinforcement learning to reason...
GPT-4 is cheaper on output ($60/M vs $60/M).
o1 offers the larger context window (200K tokens).
Choose GPT-4 for the lower output price ($60/M vs $60/M). Choose o1 if you need the larger 200K context window.
