Questions

Is GPT-4.1 better than GPT-4o (2024-08-06) for coding?

Neither model has a coding score yet, so the two cannot be ranked on coding. Pick GPT-4.1 for output tokens 1.3x cheaper ($8.00 vs $10.00 per million) and a larger context window (1.05M against 128K tokens).

Which is cheaper, GPT-4.1 or GPT-4o (2024-08-06)?

GPT-4.1 costs $2.00 per million input tokens and $8.00 per million output tokens; GPT-4o (2024-08-06) costs $2.50 and $10.00. Cost per solved task is known for GPT-4.1 only.

Which has the bigger context window, GPT-4.1 or GPT-4o (2024-08-06)?

GPT-4.1, with 1.05M tokens against 128K.

How many benchmarks is the GPT-4.1 vs GPT-4o (2024-08-06) comparison based on?

56 benchmarks have a result for both models as of October 22, 2026. GPT-4.1's coding index rests on 0 independent benchmarks and GPT-4o (2024-08-06)'s on 0. Where only one model has a result, the page says so instead of naming a winner.
