This will allow users to generate and iterate on more UI prototypes, websites, and visual projects without hitting caps as quickly.

Additionally, the company has announced that Fast Mode now defaults to Opus 4.7 in Claude Code for developers.

Fast mode is a high-speed configuration for Claude Opus, making the model 2.5x faster at a higher cost per token. Developers can toggle it on with /fast when they need speed for interactive work like rapid iteration or live debugging, and toggle it off when cost matters more than latency.

Fast mode pricing is 30/150 MTok on both Opus 4.7 and Opus 4.6. Opus 4.7 is the fast mode default in Claude Code v2.1.142 and later. Fast Mode pricing is flat across the full 1M token context window. This mode for Opus 4.7 and Opus 4.6 shares the same rate limit pool; usage on either model draws from the same limits.

This mode is said to be best for interactive work where response latency matters more than cost, like rapid iteration on code changes, live debugging sessions and time-sensitive work with tight deadlines. Currently, Fast mode is a research preview feature.
