In this Chinese-language presentation, the speaker demonstrates connecting Claude's desktop interface to DeepSeek V4 through CC Switch, with Codex handling installation and configuration. The example uses a Mac mini and provider API keys. CC Switch supplies local routing to third-party services; this is not a demonstration of running model inference on the Mac itself.

The setup starts with a Markdown handoff guide that records the goal, machine prerequisites, installation steps and provider configuration. The speaker gives this document to Codex, then uses its computer-use capability to adjust desktop settings and model names. After encountering a naming issue, the speaker asks Codex to fix it and folds the additional steps into a revised guide for future installations.

The speaker argues that Claude Code's AI agent workflow, including task planning, tool calls, file access and terminal operations, is the reason to connect another model through it. Cowork is discussed as an option for office tasks involving local files and applications.

An initial Alibaba Cloud Coding Plan setup precedes the DeepSeek connection. The speaker reports that the first setup lacked live search, while the connected DeepSeek model could search current information. These capability and cost observations describe the speaker's experience, rather than guarantees for every provider configuration.
