GPT-4.1 pricing
It is the #12 most expensive of 37 current text models priced per 1M input tokens.
Independent benchmark results
Scores come from independent evaluators that ran the model themselves, pinned to a dated snapshot. Rank is among current models in the same snapshot. OpenAI's own launch figures are listed under strengths with the publisher named, because they are not measured the same way.
| Benchmark | Score | Rank | Measured | Source |
|---|---|---|---|---|
| Arena Text | 1415 Elo | #36 of 39 | October 8, 2026 | Arena · 2026-10-12 |
| GPQA Diamond | 66.9% | #35 of 37 | October 12, 2026 | Epoch AI · 2026-10-12 |

Strengths, cautions and best uses
Strengths
- GPT-4.1 records API access for text and image inputs and a published 1,047,576-token context window
Cautions
- Not in the pinned LiveBench snapshot; its independent scores here come from Epoch AI's own GPQA Diamond, FrontierMath and SimpleQA Verified runs
Best for
- Long-context API trials using text and image inputs
