Claude Haiku 5.5
- Claude Haiku 5.5LatestFor high-volume, latency-sensitive tasks such as classification, extraction, and routing Overview Claude Haiku 5.5 is built for high-volume, latency-sensitive work such as classification, routing, extraction, and subagent tasks.
- It supports adaptive thinking with the effort parameter, a 1M token context window, and up to 128k output tokens.
- It uses the same newer tokenizer as Claude 4.7 and later models, so the same text counts as approximately 30% more tokens than on Claude Haiku 4.5.
