Executive Summary
An experimental "Fast mode" for the Claude Opus 4.7 model is now available in research preview on the AI Gateway. This new feature provides approximately 2.5 times faster output token generation while retaining the full intelligence of the standard model. Targeted at developers requiring lower latency, this performance enhancement comes at a significant premium, priced at six times the standard rate.
Key Takeaways
* Product: Fast mode for Claude Opus 4.7.
* Performance: Delivers a ~2.5x increase in output token generation speed.
* Availability: Accessible now as an early, experimental feature in research preview via the AI Gateway.
* Pricing: Costs 6x the standard Opus 4.7 rates.
* Input: $30 / 1M tokens (vs. $5 standard).
* Output: $150 / 1M tokens (vs. $25 standard).
* Implementation: Enabled by passing `speed: 'fast'` in the Anthropic provider options within an API call.
Strategic Importance
This initiative addresses the critical trade-off between model power and response speed, offering a premium, low-latency option for developers building time-sensitive applications with a state-of-the-art model.
