Amp has integrated with Claude's subscription service, directly replacing its underlying layer with Claude Code.

Beating AI Express: AI programming tool Amp has announced support for Claude Pro/Max subscriptions, with free access open to all users. To enable the feature, select the "Claude Code" mode when creating a new task and link your Claude account. Model usage will be charged directly to users’ existing subscription limits, so no separate credits need to be purchased from Amp. The new mode runs official Claude Code via the Claude Agent SDK, while preserving Amp’s existing features such as cloud PCs,
