Claude Opus 4.7 Fast Mode Now in Research Preview on API and Claude Code

Anthropic launched Claude Opus 4.7 Fast Mode in research preview, available on the Anthropic API and within Claude Code. Fast Mode delivers accelerated output for Opus 4.7—the most capable Claude model—without routing to a smaller, cheaper model. This directly addresses the latency tradeoff that has made Opus-class models impractical for interactive workflows requiring both high intelligence and responsiveness.

Why It Matters

Opus-class intelligence at fast-mode latency closes the primary practical gap between frontier-capable and production-usable AI. If Fast Mode performs as described under production loads, it removes the Opus speed penalty that has driven developers toward Sonnet-class models for agentic workflows.
