)
messages = [
{
"role": "user",
"content": "The lengths of the two legs of a right triangle are 3 cm and 4 cm respectively. Find the length of the hypotenuse of this right triangle.",
},
]This code initializes a Kimi (Moonshot AI) API shopper utilizing your API key and base URL, then prepares a consumer message asking for the hypotenuse of a 3-4-5 proper triangle. It’s able to ship this message to the Kimi API for processing.
stream = shopper.chat.completions.create(
