Claude desktop can connect to third-party inference services via developer mode

居然可以在 Claude 桌面端用三方模型了！

The post claims Claude desktop can enable developer mode while signed out, then use an API base URL and key to connect third-party inference services. It lists Help → Troubleshooting → Enable developer mode, then after restart configure third-party inference under Developer and apply locally. The key point is that this looks like a client-side entry point; the post does not disclose Anthropic's support status or model scope.

Why it matters: HKR-H/K/R all pass: the hidden developer mode is novel, reproducible, and relevant to lock-in. I keep it at 74 because this is a single X post; Anthropic has not confirmed scope, supported models, or official policy.
