A new model ID, `@anthropic-ai/claude-codez3`, was found in the latest `claude-code` binary, alongside new endpoints and a background task feature flag.
READY TO POST:
looks like anthropic's claude-code binary might be getting a new model, claude-codez3. curious what 'z3' means for code generation.
new strings in anthropic's claude-code binary point to a new model_id, claude-codez3, and some desktop-specific endpoints. could be a desktop code assistant coming.
