BenchLM is tracking Composer 2 by Cursor. Some benchmark data is visible, but not enough non-generated coverage is available for a leaderboard rank yet.
BenchLM is tracking Composer 2, but this profile is currently excluded from the public leaderboard because it still lacks enough trustworthy benchmark coverage to rank safely. Generated rows may still appear below for context, but they are not enough on their own to make this model ranking-eligible.
Composer 2 is a proprietary model with a 200K 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.
This profile currently has 3 of 61 tracked benchmarks. BenchLM uses discounted fallback estimates where necessary so missing categories do not collapse the overall score, but public sourced rows still carry more weight than inferred ones.

BenchLM is still missing enough trustworthy benchmark coverage to rank this model across the public leaderboard. Trusted benchmark rows remain visible below for reference.
Composer 2 has 3 sourced benchmark scores on BenchLM, but it does not yet have enough trustworthy non-generated coverage to receive a global overall rank.
Composer 2 has visible benchmark coverage in coding and programming, but BenchLM does not currently assign it a global category rank there.
Composer 2 has visible benchmark coverage in agentic tool use and computer tasks, but BenchLM does not currently assign it a global category rank there.
Not yet. Composer 2 currently has 3 sourced benchmark scores out of the 61 benchmarks BenchLM tracks. BenchLM may use discounted fallback values for missing categories, but trustworthy public rows still carry more weight than inferred ones.
Composer 2 has a context window of 200K, which determines how much text it can process in a single interaction.
