Anthropic Ships Faster Claude Opus Mode
Anthropic today releases a research-preview 'fast' mode for its Claude Opus 4.6, accessible via /fast in Claude Code and the API, promising a 2.5x faster variant. Fast mode charges $30/million input and $150/million output (50% discount until Feb 16), and Opus 4.6 also offers a 1,000,000-token context option at higher prices; documentation omits measured latency.
