Claude Code Adds Fast Mode
Claude Code’s Fast Mode delivers up to 2.5× faster Opus responses while preserving the same model quality and capabilities. It is a research preview aimed at interactive coding, with higher per-token costs and usage-credit billing.
Fast Mode looks valuable for live debugging and rapid iteration, but its premium pricing makes it a poor default for long autonomous coding sessions.
- –Uses the same Opus model rather than a weaker, distilled variant
- –Up to 2.5× faster output can make interactive development feel substantially more responsive
- –Standard mode remains better suited to background work, batch jobs, and cost-sensitive workflows
- –Enabled with `/fast`, with availability depending on supported Opus models and account access
- –Subscription users pay through usage credits, so extended sessions can become expensive quickly
