- Use provider model ID "moonshotai/Kimi-K3.1-Pro", not the LLMReference slug "kimi-k3-1-pro".
- Together uses "organization/model-name" format, e.g. "meta-llama/Llama-4-Scout-17B-16E-Instruct" or "Qwen/QwQ-32B". See the Together model catalog for the exact ID.
- The examples expect TOGETHER_API_KEY; rename it only if your application config maps the new variable.
