Understand the event

AI overview

Anthropic has ended the research preview and removed the waitlist for Opus 5.5 fast mode on the Claude Platform, making what it describes as the same model available at up to 2.5 times the speed. API access costs $8 per million input tokens and $40 per million output tokens, twice the standard Opus 5.5 rates. Fast mode is also available through Microsoft Foundry, with Google Cloud availability coming soon. In Claude Code, subscribers including Pro and Max users can enable fast mode with /fast, but its charges draw from separately purchased extra usage credits rather than their subscription allowance. Team and Enterprise users need an administrator to enable it first.
