Haiku 5.5 lowers prices, then rates jump fivefold above 100,000 tokens
Anthropic launched Haiku 5.5 on October 7. For prompts up to 100,000 tokens, its API lists $0.10 per million input tokens and $0.50 per million output tokens. Above that threshold, the rates rise to $0.50 and $2.50.

These are Anthropic's list prices, not measured costs per finished job. Anthropic bases its claim of roughly 75% average savings on assumptions about request lengths and its updated tokenizer. It still recommends larger models for complex agentic coding.
Compare completed work, errors and retries at the prompt lengths the application actually sends.
