Quick fix

A user restored 1M with a Python proxy returning model IDs with the [1m] suffix and context_window: 1048576; no reusable code or official fix was provided.

curl http://127.0.0.1:15721/v1/models returns {"models":[]}

Cause

A user reported that connecting Claude Desktop to the cc-switch DeepSeek Anthropic proxy on macOS made /v1/models return an empty list, leaving the model selector empty and reducing context to 200k, even with supports1m: true set on all routes. The user reported that /v1/messages still forwarded requests normally and that model pricing data in the database and provider flags were correct. The user noted that DeepSeek's Anthropic endpoint has no /v1/models and traced the problem to cc-switch's model list synthesis logic.

The user suspected the 3.15.0 change replacing the old [1M] suffix with the supports1m flag, but no maintainer confirmed the root cause in the thread. The user reported restoring 1M support with a minimal Python proxy, making this a user-tested workaround. The issue was later closed as a duplicate; this does not establish that cc-switch fixed it.

Fix

1. 1

   Check whether your setup matches the report: Claude Desktop connects to the DeepSeek Anthropic endpoint through cc-switch with supports1m: true, but http://127.0.0.1:15721/v1/models still returns an empty model list. The report also states that /v1/messages works normally.

2. 2

   The user-reported workaround uses a minimal Python proxy to make /v1/models return model IDs with the [1m] suffix and include context_window: 1048576. The user said this restored 1M support, but provided no proxy code or complete deployment steps.
