Just change two lines of code:
# Before (OpenAI)
client = OpenAI(api_key="sk-...")
# After (AI Token — Chinese LLMs)
client = OpenAI(
api_key="your-ai-token-key",
base_url="https://eaf9553505eeb8f5-115-190-107-107.serveousercontent.com/v1"
)
That's it. Same SDK, same API format, same response structure. Works with LangChain, LlamaIndex, Cursor, and all OpenAI-compatible tools.
Best coding model. Beats GPT-4o on benchmarks.
Cheapest option. Great for high-volume tasks.
Reasoning model. Better than o1 at lower cost.
128K context. Excellent for document analysis.
