Anthropic opens Opus 5.5 fast mode on Claude at $8/$40 per million tokens

Top News · Reported · aihot.news · translated from Chinese

If you have been waiting for access to Opus 5.5 fast mode on the Claude platform, you no longer need a waitlist slot. Anthropic has ended the research preview, opening access to the faster serving option for the same Opus 5.5 model.

Here's what you get:

• Fast mode is priced at $8/$40 per million tokens on the Claude platform.
• Opus 5.5 runs at up to 2.5 times the speed in fast mode, without switching models.
• Microsoft Foundry also offers fast mode, with inference hosted on Azure.

One catch: Google Cloud support is still coming soon. Claude Code fast mode remains unchanged and continues to use additional usage credits, so this update does not change your Claude Code setup.
