Anthropic cut Claude Opus 4.5 pricing from $15 to $5 per million input tokens and from $75 to $25 per million output tokens — a 67% reduction.
The move repositioned the former flagship from a "boutique" model to a production-ready enterprise tool, undercutting rivals and signaling the broader AI pricing war.
For teams that were priced out of Opus 4.5, this makes it a compelling option that's now in the same ballpark as competing flagship models.
