GenAI Stack
A starter stack combining LangChain, Neo4j and Ollama with Docker, meant as a template and set of demo applications for building a GenAI application.
GenAI Stack is configured through a .env file copied from env.example, with variables for the Ollama API URL, the Neo4j connection, the LLM to use, and the embedding model.
The LLM variable accepts any Ollama model tag or GPT-4 and GPT-3.5, and the embedding model can be a sentence-transformer, OpenAI, AWS, Ollama, or Google GenAI embedding. On macOS, Ollama runs separately with ollama serve; on Linux, it can run inside the stack using a dedicated Docker Compose profile. Optional environment variables enable LangSmith tracing.
