Our take
o1 is 1.5x cheaper for a typical chat. o1 scores higher on the Artificial Analysis Intelligence Index (15.2 vs 6.7). o1 has the larger context window (200K vs 8K tokens). The right pick depends on your workload, so the quickest way to settle it is to send the same prompt to both and compare.
FAQ
Frequently asked questions
Is o1 or GPT-4 cheaper?
o1 is cheaper for a typical chat (2K input tokens and 500 output tokens). o1 costs $15 per 1M input tokens and $60 per 1M output tokens, while GPT-4 costs $30 per 1M input tokens and $60 per 1M output tokens.
Which has a bigger context window, o1 or GPT-4?
o1 supports up to 200K tokens of context, compared with 8K for GPT-4.
Is o1 smarter than GPT-4?
On the Artificial Analysis Intelligence Index, o1 scores 15.2 and GPT-4 scores 6.7, putting o1 ahead. Benchmarks don't capture everything, so the best test is running your own prompts through both.
Can I use o1 and GPT-4 at the same time?
Yes. Shortcut Chat sends one prompt to multiple models at once, so you can see o1 and GPT-4 answer side by side and keep the better response.
Why choose? Ask both.
Send one prompt to o1 and GPT-4 at the same time. Compare the answers side by side and keep the best one.
