As of October 20, 2026, OpenAI GPT-5 Nano ranks #130 of 213 models overall with 13.0 on the Artificial Analysis Intelligence Index. Its strongest category is math, where it ranks #73 of 116. OpenAI GPT-5 Nano costs $0.05 per million input tokens and $0.40 per million output tokens. It was released on August 7, 2025.
Its output price ranks 71 of 349 priced models, counting from the cheapest.
GPT-5-Nano is the smallest and fastest variant in the GPT-5 system, optimized for developer tools, rapid interactions, and ultra-low latency environments. While limited in reasoning depth compared to its larger...
openai/gpt-5-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.
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.
