Fast mode support for Claude Opus 4.6 is now available on AI Gateway.
Fast mode is a premium high-speed option that delivers 2.5x faster output token speeds with the same model intelligence. This is an early, experimental feature.
Fast mode's increased output token speeds enable new use cases, especially for human-in-the-loop workflows. Run large coding tasks without needing to context switch and get planning results without extended waits.
To enable fast mode, pass in the provider options in AI SDK:speed: 'fast'anthropic
You can use fast mode with by setting the variable in your shell configuration file or in .Claude Code via AI GatewayCLAUDE_CODE_SKIP_FAST_MODE_ORG_CHECK~/.claude/settings.json
Try fast mode directly in the .AI Gateway playground for Opus 4.6
Fast mode is priced at 6x standard Opus rates.
All standard pricing multipliers (e.g., prompt caching) apply on top of these rates.
Standard | Fast Mode |
