Grok 4.1 Fast (Reasoning)
BenchLM is tracking Grok 4.1 Fast (Reasoning), but this profile is currently excluded from the public leaderboard because it still lacks enough non-generated benchmark coverage to rank safely. Only non-generated public benchmark rows appear below.
Grok 4.1 Fast (Reasoning) is a proprietary model with a 2M 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.
Grok 4.1 Fast (Reasoning) sits inside the Grok 4.1 Fast family alongside Grok 4.1 Fast. This profile currently has 1 of 178 tracked benchmarks. BenchLM only exposes non-generated benchmark rows publicly, so missing categories stay blank until a sourced evaluation is available.
