Config Claude Desktop with DeepSeek
UPDATE: Add a system environment variable using name “NODE_ENV” with value “production” and restart Claude Desktop. Now you can directly add only DeepSeek models to the model list without need to manually modify the config json file mentioned in this post:

deepseek-v4-flash
======================================
