Anthropic launched Claude Opus 5 with 1M context, 128k max output, default thinking, and Opus 4.8 pricing.

The point is higher context and output capacity at the prior Opus price, reducing upgrade friction for API builders.

It sits next to Opus 4.8 as same-priced successor, so long-context builds can move without a price change.
