What happened
Claude Haiku 5.5 costs about 75% less to run than its predecessor and targets high-volume jobs like summaries and live customer support. It arrives 15 days after Opus 5.5.
Reported details
- Anthropic launched Claude Haiku 5.5 with 75% lower average costs, cut Sonnet cache pricing and announced API credits for Max and Team users.
Why this matters
This reads as a change in infrastructure rather than a move in price, and that distinction decides what is worth verifying: whether the underlying record moved, or only the interface around it. If a ledger, custodian or settlement term is unchanged, then anything built on top of it behaves the same too, however the announcement is framed. Subject of the report: Anthropic.
Evidence boundary
The scope is limited to what the linked reports state, and where two of them diverge both positions are recorded without either being picked in advance.
What to verify
If Anthropic points at a contract or a chain, verify the deployed address and version there. If it describes an internal or corporate change with no on-chain component, the chain is the wrong place to look.
