Call GPT-6.1 Sol or Qwen3.8 Max with LiteLLM

Both use the OpenAI format through LiteLLM, so switching is a model name change. Set each provider's API key in the environment first.

Python SDK

from litellm import completion

messages = [{"role": "user", "content": "Hello!"}]

# GPT-6.1 Sol
response = completion(model="gpt-6.1-sol", messages=messages)

# Qwen3.8 Max
response = completion(model="dashscope/qwen3.8-max", messages=messages)

# GPT-6.1 Sol, falling back to Qwen3.8 Max if the call fails
response = completion(model="gpt-6.1-sol", messages=messages, fallbacks=["dashscope/qwen3.8-max"])
