Fast mode is enabled by passing `speed: 'fast'` in the Anthropic provider options via the AI SDK, or by setting `"fastMode": true` in settings.json for Claude Code via AI Gateway. The feature targets human-in-the-loop workflows like large coding tasks and planning, where reduced latency matters. Standard pricing multipliers such as prompt caching apply on top of the 6x rate. ## Full article daily.dev links to this article rather than hosting it.
