Anthropic's Claude Opus 5 doubles cost for max effort, offers 1M context

By PulseAugur Editorial · [1 sources] ·

Anthropic has released Claude Opus 5, which offers a 1M context window and five effort levels, with 'thinking' enabled by default. While the base API pricing remains unchanged from Opus 4.8, the new 'max effort' setting significantly increases costs, with evaluations showing a 94% cost increase for a 2-point gain in the Artificial Analysis Intelligence Index. The model's default 'thinking' feature and longer output tendencies can also lead to higher bills than anticipated, making careful selection of effort levels and modes crucial for cost management. AI

IMPACT New effort-level controls in Claude Opus 5 necessitate careful cost management for users, potentially impacting API spending strategies.
