Symptoms

Requests return 404: "model 'xyz' not found, make sure the correct model ID was used and that you have access to the model."

Why it happens

• Typo in the model ID
• Model retired (embed-english-v2.0 family on April 4, 2026; rerank v2 models; command and command-light were deprecated in September 2025)
• Using an old alias such as command-r-plus that pointed to a deprecated version
• No access to the model on your account
