- Fast mode is in research preview, with feature, pricing, and availability subject to change.
- Fast mode uses the same Opus 4.6 model but prioritizes speed over cost efficiency.
- Toggle fast mode via `/fast` in CLI or VS Code Extension, or set `"fastMode": true` in user settings.
- Pricing starts at $30/150 MTok with a 50% discount until February 16.
- Available to all subscription plans (Pro/Max/Team/Enterprise) and Claude Console, but not included in subscription rate limits.
- Fast mode is best for interactive work like rapid iteration, live debugging, and time-sensitive tasks.
- Higher per-token pricing compared to standard Opus 4.6, with input/output costs varying by token count.
- Requires extra usage enabled and admin enablement for Teams/Enterprise organizations.
- Fast mode has separate rate limits; hitting them falls back to standard Opus 4.6.
- Research preview means the feature may evolve based on feedback.
