LLM7 model guide

LangChain with LLM7

Configure LangChain with LLM7: eligible models, setup instructions, and a copyable configuration.

Requirements and limitations

Only standard Chat Completions behavior is inferred. Provider-specific extensions and Responses API features are outside this template.

Setup

Install the Python dependency with pip install langchain-openai.
Set LLM7_API_KEY in your environment; the placeholder below must be replaced.
Run the ChatOpenAI example. Bind tools only when the selected model reports tool support.
