Agent runs you start, and chats you set to run on Claude Code, use your own Claude plan. Without one, they use API keys. Only your runs and chats use it. Anthropic only allows a subscription inside Claude Code itself, so chats on it run Claude Code in a sandbox. Step-by-step setup

Chats you set to run on My Anthropic API key call Claude with it, billed to your Anthropic account rather than the workspace's keys. Same assistant and tools as the workspace chat. Only your chats use it.

Agent runs you start can use the models on your Alibaba Coding Plan (Qwen3.7/3.6/3.5 Plus, GLM-5, Kimi K2.5, MiniMax M2.5) through Claude Code, with no Mimir budget cap. Pick one when you start a run, or let a routing rule choose it. Use the Plan-Specific API Key from the Coding Plan page, not a pay-as-you-go Model Studio key. Only your runs use it.
