Claude Haiku 4.5: faster, more local

Anthropic ships Haiku 4.5. 2× faster than 4.4, and for the first time, an officially supported local deployment mode for businesses. We tested it for a week.

What changed

Latency dropped to 180 ms p50 on commodity Apple Silicon. Memory footprint is down 30%. The local mode ships as a single binary with deterministic outputs.
