Moonshot AI Limitations & LiteLLM Handling

LiteLLM automatically handles the following Moonshot AI limitations to provide seamless OpenAI compatibility:

Temperature Range Limitation

Limitation: Moonshot AI only supports temperature range [0, 1] (vs OpenAI's [0, 2])
LiteLLM Handling: Automatically clamps any temperature > 1 to 1

Temperature + Multiple Outputs Limitation

Limitation: If temperature < 0.3 and n > 1, Moonshot AI raises an exception
LiteLLM Handling: Automatically sets temperature to 0.3 when this condition is detected

Tool Choice "Required" Not Supported

Limitation: Moonshot AI doesn't support tool_choice="required"
LiteLLM Handling: Converts this by:

• Adding message: "Please select a tool to handle the current issue."
• Removing the tool_choice parameter from the request
