GPT-4 or GPT-4.1: which to pick

Neither model has a coding score yet, so the two cannot be ranked on coding.

Pick GPT-4 for work measured by SWE-bench Verified or LMArena Text: coding, where it leads.

Only benchmarks that tested both models count toward a pick; a result only one model has is shown but not compared.

Which one for your work

Each card is decided by one number both models carry. Where only one has it, the card says so and makes no call.

Benchmark by benchmark

First the score: boards each model leads, per category, where both have a result. Then every board, a category to a fold; bars are each result on a 0 to 100 scale, so compare the two in a row, not one row with another.

Questions

Is GPT-4 better than GPT-4.1 for coding?

Neither model has a coding score yet, so the two cannot be ranked on coding. Pick GPT-4 for work measured by SWE-bench Verified or LMArena Text: coding, where it leads.

Which is cheaper, GPT-4 or GPT-4.1?

GPT-4 costs $30.00 per million input tokens and $60.00 per million output tokens; GPT-4.1 costs $2.00 and $8.00. Cost per solved task is known for GPT-4.1 only.

Which has the bigger context window, GPT-4 or GPT-4.1?

GPT-4.1, with 1.05M tokens against 8K.

How many benchmarks is the GPT-4 vs GPT-4.1 comparison based on?

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