GPT-4o (2024-05-13) vs o1
o1 leads GPT-4o (2024-05-13) on the Artificial Analysis Intelligence Index, 15.2 to 7.3, and GPT-4o (2024-05-13) costs 4.0x less per output token ($15.00 vs $60.00 per million). Updated October 22, 2026; 41 benchmarks have a result for both.
GPT-4o (2024-05-13) or o1: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GPT-4o (2024-05-13) for output tokens 4.0x cheaper ($15.00 vs $60.00 per million) and work measured by AA Coding Index or LiveCodeBench (Artificial Analysis run), where it leads.

Questions
Is GPT-4o (2024-05-13) better than o1 for coding?
Neither model has a coding score yet, so the two cannot be ranked on coding. Pick GPT-4o (2024-05-13) for output tokens 4.0x cheaper ($15.00 vs $60.00 per million) and work measured by AA Coding Index or LiveCodeBench (Artificial Analysis run), where it leads.
Which is cheaper, GPT-4o (2024-05-13) or o1?
GPT-4o (2024-05-13) costs $5.00 per million input tokens and $15.00 per million output tokens; o1 costs $15.00 and $60.00. Cost per solved task is known for neither of them.
Which has the bigger context window, GPT-4o (2024-05-13) or o1?
o1, with 200K tokens against 128K.
How many benchmarks is the GPT-4o (2024-05-13) vs o1 comparison based on?
41 benchmarks have a result for both models as of October 22, 2026. GPT-4o (2024-05-13)'s coding index rests on 0 independent benchmarks and o1's on 0. Where only one model has a result, the page says so instead of naming a winner.
