AI Impact Summary
Anthropic has launched Claude Opus 4.6 with a new "Fast Mode" offering up to 2.5x faster output token generation at a premium price. This represents a significant capability upgrade, particularly for applications requiring rapid response times. The introduction of Fast Mode and the deprecation of older models (Sonnet 3.7, Haiku 3.5) necessitate a migration strategy for existing users, and the new effort parameter replaces the deprecated budget_tokens for controlling thinking depth.
