LangChain

Status: Candidate setup, not yet verified by NexoRouter.

LangChain can call OpenAI-compatible chat endpoints by setting a custom base URL.

Python example

from langchain_openai import ChatOpenAI

model = ChatOpenAI(
    api_key=os.environ["NEXOROUTER_API_KEY"],
    base_url="https://api.nexorouter.com/v1",
    model="deepseek-v4-flash",
)

print(model.invoke("Write one short production checklist.").content)

Verify

Run a single chat call first. Check Usage Logs before adding chains, tools, retrievers, or agents.

Boundaries

  • Vector stores require embeddings, which are not documented as stable yet.
  • Tool and agent behavior depends on model tool calling.
  • Keep model IDs configurable.
