BenchLM is tracking GPT-5.4 nano by OpenAI. Some benchmark data is visible, but trusted coverage is not complete enough for ranking yet.
BenchLM is tracking GPT-5.4 nano, but this profile is currently excluded from the trusted leaderboard because its source-backed benchmark coverage is not complete enough yet. We keep the model metadata and any verified benchmark rows visible while the rest of the public eval record is re-checked.
GPT-5.4 nano is a proprietary model with a 400K token context window. It uses explicit chain-of-thought reasoning, which typically improves performance on math and complex reasoning tasks at the cost of higher latency and token usage.
GPT-5.4 nano sits inside the GPT-5.4 family alongside GPT-5.4, GPT-5.4 Pro, GPT-5.4 mini. BenchLM links it directly to GPT-5 nano as the earlier related model in that lineage. This profile currently has 1 trusted benchmark rows on BenchLM, but that is not enough for a leaderboard rank yet.

BenchLM is still verifying enough trusted benchmark coverage to place this model in the leaderboard. Category ranks will appear here once that source-backed coverage is complete.
BenchLM is tracking GPT-5.4 nano, but trusted source-backed benchmark coverage is still coming soon. We currently list its creator, model type, and context window while we wait for verified public benchmark results.
GPT-5.4 nano belongs to the GPT-5.4 family. Related variants on BenchLM include GPT-5.4, GPT-5.4 Pro, GPT-5.4 mini.
GPT-5.4 nano is tracked on BenchLM, but its current source-backed benchmark coverage is not strong enough for a trusted leaderboard rank yet. We keep the model page live while we verify more public benchmark results.
GPT-5.4 nano has a context window of 400K, which determines how much text it can process in a single interaction.
