Claude Haiku 4.5 ranks #77 out of 200 models on the public leaderboard with an overall score of 56.58/100. 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.

Claude Haiku 4.5 is a proprietary model with a 200K token context window. It processes queries without explicit chain-of-thought reasoning, offering faster response times and lower token usage.

Claude Haiku 4.5 sits inside the Claude Haiku 4.5 family alongside Claude Haiku 4.5 Thinking. This profile currently has 5 of 321 tracked benchmarks. BenchLM only exposes non-generated benchmark rows publicly, so missing categories stay blank until a sourced evaluation is available.

Its strongest category is Agentic (#46), while its weakest is Coding (#77). This performance profile makes it particularly useful for coding agents, browser research, and computer-use workflows.

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.
