Steven · 2026-07-24

Anthropic released Claude Opus 5 today, and it's already on the site.

FEATAdded claude-opus-5 to the calculator and analyzer. Pricing is unchanged from Opus 4.8, $5 per million input tokens and $25 per million output, but Anthropic says it closes most of the gap to Fable 5 at half the cost.

FEAT1M token context window, 128K max output, same as the rest of the current Claude lineup.

FEATIt's tagged as a frontier model, so it'll show up with the Frontier only toggle switched on.

See where it lands on price.
