THEN For base_url, upgrade langchain-ollama to version >= 0.1.1 (which includes PR #24719) or set the OLLAMA_BASE_URL environment variable. For seed, note that it is not yet supported; omit it or use a workaround such as fixing random seeds in the underlying model if possible. Always test that custom Ollama server endpoints are actually used.

# Workaround for base_url:
import os
os.environ["OLLAMA_BASE_URL"] = "http://your-server:11434"
llm = ChatOllama(model="llama3")  # now uses the env var
