Claude Haiku 5.5 in Claude Code: Cut AI Coding Costs 20x
Anthropic released Claude Haiku 5.5 on October 7, 2026, and the headline number is hard to ignore: $0.10 per million input tokens, a tenth of Sonnet 5.5 and a fortieth of Opus 5.5. The real question for anyone running Claude Code daily is not the price, though. It is which jobs a $0.10 model can take away from a $2 model without your pull requests noticing. I dug through the launch benchmarks,…
Claude Haiku 5.5 launched Oct 7, 2026 at $0.10 per million input tokens, 1/10 the price of Sonnet 5.5 and 1/40 of Opus 5.5. The key question is what jobs can this $0.10 model replace in daily coding tasks.
After analyzing launch benchmarks, independent coding tests and pricing details, Claude Haiku 5.5 emerges as Anthropic's cheapest and fastest model. It is the first Haiku to survive an agent loop with higher scores than Haiku 4.5.
For narrow, verifiable work like subagent lookups, extraction, summaries and one-shot fixes, route such tasks to Haiku 5.5 at $0.10/$0.50 per million tokens. Keep Sonnet 5.5 as the default coder for more complex coding jobs.
Important pricing detail: Haiku 5.5 charges $0.10 until 100K tokens, then jumps to $0.50/$2.50 for the entire request. This 100K token cliff can 5x the price of longer prompts. Compact context before reaching 100K to stay in the cheaper tier.
Verification is crucial. Route tasks to Haiku 5.5 when you can verify its output for less than the price gap to Sonnet or Opus. Tasks that require judgment calls fall outside Haiku's price gap and are better off with the more capable but pricier models.
In summary, Claude Haiku 5.5 is a small but capable model that can outperform larger models on structured agent tasks at a fraction of the cost. The key is understanding the 100K token pricing cliff and verifying output before delegating to Haiku.
