As of October 20, 2026, OpenAI GPT-4.1 Nano ranks #171 of 213 models overall with 7.8 on the Artificial Analysis Intelligence Index. Its strongest category is math, where it ranks #97 of 116. OpenAI GPT-4.1 Nano costs $0.10 per million input tokens and $0.40 per million output tokens. It was released on April 14, 2025.
Its output price ranks 71 of 349 priced models, counting from the cheapest.
For tasks that demand low latency, GPT‑4.1 nano is the fastest and cheapest model in the GPT-4.1 series. It delivers exceptional performance at a small size with its 1 million...
openai/gpt-4.1-nano The tick on a coding bar is the median of every model measured on it. Outside coding, the place is this model's rank on that board. A board that never ran the model says so.
Measured in 5 of 6 categories. A place counts only the models measured on that board.
The index averages only the coding benchmarks that have a result; the others are skipped, never filled in. How it is weighted

A list price says what a token costs. The cost per solved task says what a working answer costs, which is the number that decides.
Neither board that publishes what a SWE-bench Verified attempt costs, Vals AI and swebench.com, has run this model. We leave the number out rather than estimate it.
Beside a result, many boards publish what the run cost, how long it took, the tokens it spent or the votes behind a rating. Each figure as its board printed it, one board per row.
