## AI overview

Vercel AI Gateway now supports an experimental fast mode for Claude Opus 4.6, providing 2.5x faster output token generation with the same model intelligence. It can be enabled through AI SDK provider options, used with Claude Code, or tested in the AI Gateway playground. Fast mode costs six times the standard Opus rates.

## Source excerpt

Fast mode support for Claude Opus 4.6 is now available on AI Gateway. Fast mode is a premium high-speed option that delivers 2.5x faster output token speeds with the same model intelligence. This is an early, experimental feature. Fast mode's increased output token speeds enable new use cases, especially for human-in-the-loop workflows. Run large coding tasks without needing to context switch and get planning results without extended waits. To enable fast mode, pass speed: 'fast' in the anthropic provider options in AI SDK: You can use fast mode with Claude Code via AI Gateway by setting the CLAUDE_CODE_SKIP_FAST_MODE_ORG_CHECK variable in your shell configuration file or in ~/.claude/settings.json. Try fast mode directly in the AI Gateway playground for Opus 4.6. Fast mode is priced at 6x standard Opus rates. Standard Fast Mode Input: $5 / 1M tokens Output: $25 / 1M tokens Input: $30 / 1M tokens Output: $150 / 1M tokens All standard pricing multipliers (e.g., prompt caching) apply on top of these rates.
