Qwen3.5 397B (Reasoning) ranks #56 out of 200 models on the public leaderboard with an overall score of 59.5/100. 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.
Qwen3.5 397B (Reasoning) is a open weight model with a 128K 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.
Qwen3.5 397B (Reasoning) sits inside the Qwen3.5 397B family alongside Qwen3.5 397B. This profile currently has 17 of 321 tracked benchmarks. BenchLM only exposes non-generated benchmark rows publicly, so missing categories stay blank until a sourced evaluation is available.
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.
