Claude Code v2.1.321 adds Claude Fable 5.2, which is now the default Fable model. The release lists a 1M-token context window, prices of $8 and $40 per million tokens, and $0.20 per million tokens for cache reads. Saved Fable 5.1 selections move to fable on Pro and Max plans immediately, and on Team and Enterprise plans once an organization allows it.
The claude remote-control command gains a --settings flag that applies a settings file to every session it starts. If that file changes, no new session starts until the command is restarted.
Fixes include MCP OAuth requests that could send refresh tokens to another host after a server redirect, and a read-only Bash command that ran outside the sandbox without a permission prompt. Deny rules and protected-file prompts now also cover files written by cp or mv into a directory, and WebFetch now fails with a clear error when the model returns no text instead of passing 'No response from model' to Claude as page content.
Why it matters if you build agents
Agents that use the default Fable model in Claude Code will now run on Claude Fable 5.2, with the 1M-token context and the listed pricing. Teams that depend on MCP OAuth, sandboxed Bash or deny rules should review the fixed cases against their own setups.
