Set up LlamaIndex

The examples use MoonshotAI: Kimi K3, a live model on llm.buzz. Any model name from the Models page works.

  1. Create a key in the llm.buzz console under Keys, and keep it in the LLM_BUZZ_KEY environment variable.

  2. Install llama-index-llms-openai-like and point OpenAILike at llm.buzz.

    Python
    import os
from llama_index.llms.openai_like import OpenAILike
 
llm = OpenAILike(
    model="moonshotai/kimi-k3",
    api_base="https://api.llm.buzz/api/v1",
    api_key=os.environ["LLM_BUZZ_KEY"],
    is_chat_model=True,
    context_window=128000,
)
print(llm.complete("Hello"))
