Methods to Entry Kimi k1.5?

Right here we’re going to see entry and use Kimi k1.5 utilizing an API.

API Entry of Kimi k1.5

• Log in to KIMI’s administration console
• Register an account along with your cellphone quantity
• Click on on API Key administration
• Click on on Create New and enter a reputation
• The API Key appears to be like like sk-xxxxxxxxxxx

Right here’s an instance of calling Kimi k1.5:

from openai import Shopper
consumer = Shopper(
 api_key="YOUR_KIMI_KEY",
 base_url="https://api.moonshot.ai/v1",
)
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 consumer 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 = consumer.chat.completions.create(
 mannequin="kimi-k1.5-preview",
 messages=messages,
 temperature=0.3,
 stream=True,
 max_tokens=8192,
)

It sends the ready message to the Kimi API utilizing the required mannequin, temperature, and token restrict, and units up a streaming response to deal with probably lengthy outputs. It’s designed to obtain a step-by-step or chunked reply from Kimi.

for chunk in stream:
 if chunk.selections[0].delta:
     if chunk.selections[0].delta.content material:
         print(chunk.selections[0].delta.content material, finish="")

It iterates by the streamed response from the Kimi API. For every chunk of the response, it checks if there’s new textual content content material (chunk.selections[0].delta.content material). In that case, it prints that textual content to the console, successfully displaying the mannequin’s response in actual time because it’s generated.
