Model list

​

Your own key

• A name from the list reaches the same model on your key, whether or not your organization has it turned on.
• A vendor’s own model name works only with your key. gpt-*, chatgpt-* and o1 to o9 names go to OpenAI, claude-* to Anthropic, gemini-* to Google, and openrouter/<OpenRouter model id> to OpenRouter, for example gpt-6-luna or claude-haiku-5-5. Without a key such a name returns 400 with code: "missing_provider_key".
• The request reaches the vendor as you sent it, so it uses that vendor’s own fields.
• A wrong or refused key gets the vendor’s own error and status. Moss never retries the call on the Moss key.
• The key goes only to that vendor and is never stored.
