nano

GPT-4.1 nano ranks #161 out of 200 models on the public leaderboard with an overall score of 42.06/100. It does not yet have enough sourced coverage for BenchLM's verified leaderboard. While not a frontier model, it offers specific advantages depending on the use case.

GPT-4.1 nano is a proprietary model with a 1M token context window. It processes queries without explicit chain-of-thought reasoning, offering faster response times and lower token usage.

GPT-4.1 nano sits inside the GPT-4.1 family alongside GPT-4.1, GPT-4.1 mini. This profile currently has 21 of 323 tracked benchmarks. BenchLM only exposes non-generated benchmark rows publicly, so missing categories stay blank until a sourced evaluation is available.

Its strongest category is Instruction Following (#21), while its weakest is Coding (#102). This performance profile makes it a well-rounded choice across a range of tasks.

Peer position

Exact provisional scores and ranks for the closest listed peers. A score can appear before a model clears the evidence threshold for a rank, so equal scores can have different rank states.
