You see this error in your terminal: There is an issue with the selected model (deepseek-v4-pro).

I thought a new update blocked my DeepSeek API keys. I wasted 30 minutes on this theory.

The cause was a simple typo. I used a script to set my environment variables. Two lines merged into one. A missing newline broke the setup.

The shell saw one corrupt line. Your auth token did not export. Your base URL became nonsense.

Fix it by checking your script:

• Wrong: export ANTHROPIC_BASE_URL=... export ANTHROPIC_AUTH_TOKEN=...
• Right: export ANTHROPIC_BASE_URL=https://api.deepseek.com/anthropic export ANTHROPIC_AUTH_TOKEN=sk-xxx

One other tip: Resuming sessions across providers is a one-way door.

• Anthropic to DeepSeek works.
• DeepSeek to Anthropic fails with a 400 error.

Check your newlines. Save your time.
