Data as of August 7, 2026 · How the score is built
Strongest published evidence
Agentic ranks #49. Particularly useful for coding agents, browser research, and computer-use workflows.
Validate before choosing
5 published rows leave some tracked benchmark slots empty. Independent runtime speed has not been measured.
Decision snapshot
Each value carries a field reference instead of floating alone. Markers compare this model with the current ranked and priced catalog; they are not absolute quality thresholds.

How much of this is verified
Coverage is split by category so a strong number never hides a thin evidence base. Verified means the row is tied to a published source; provisional rows remain visible but separate.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track Composer 2, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.
Composer 2 is a proprietary model with a 200K context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.
Official exact-value snapshot sourced from the Cursor Composer 2 report, Cursor's public evals page, and the public React Native Evals leaderboard.
Composer 2 sits in the Composer family with Composer 2.5, Composer 2 Fast. 5 of 381 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.
Its strongest eligible category is Agentic at #49, while its lowest eligible position is Coding at #56. particularly useful for coding agents, browser research, and computer-use workflows.

Frequently asked questions
How does Composer 2 perform overall in AI benchmarks?
Composer 2 has 5 source-displayable benchmark rows, but it does not qualify for a public overall rank. The available rows remain visible by category without being converted into a site-wide score. Missing evidence stays blank instead of being estimated from an earlier model.
Is Composer 2 good for coding and programming?
Composer 2 ranks #56 out of 132 eligible models for coding and programming, with a public category score of 51/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is Composer 2 good for agentic tool use and computer tasks?
Composer 2 ranks #49 out of 132 eligible models for agentic tool use and computer tasks, with a public category score of 50.4/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Which sibling models are related to Composer 2?
Composer 2 belongs to the Composer family. Related tracked variants include Composer 2.5, Composer 2 Fast. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
Does Composer 2 have full benchmark coverage on BenchLM?
No. Composer 2 currently has 5 source-displayable rows across 381 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of Composer 2?
Composer 2 has a reported context window of 200K in the exact-model catalog record. The value stays visible, but the profile marks its source link as unavailable instead of presenting it as directly documented. Maximum output length remains separate because providers often publish a different limit.
Last updated August 7, 2026. Runtime fields remain blank until a sourced snapshot exists.
