LangGraph vs Ollama
A comprehensive technical comparison to help you choose the right open-source foundation for your business.
LangGraph
LangGraph is a Python library by LangChain for building stateful, multi-actor applications with LLMs, modeled as persistent graphs.
Ollama
Ollama is an open-source tool that allows you to run, create, and share large language models locally on your own hardware.
Core Capabilities
- Build highly controllable, stateful AI agent workflows
- Support for cyclic graphs (loops) essential for agentic planning and reflection
- Built-in persistence and state management across execution steps
- Human-in-the-loop support (pause workflow for user approval before continuing)
- Native integration with the entire LangChain tooling ecosystem
- Fine-grained control over multi-agent handoffs and communication limits
- Streaming support to output tokens as the graph executes
Core Capabilities
- Run large language models (LLMs) locally on CPU and GPU
- Support for popular models like Llama 3, Mistral, and Gemma
- Custom model creation via Modelfile
- REST API for seamless integration with applications
- Cross-platform support (macOS, Linux, Windows)
- Docker containerization for easy deployment
- Integration with LangChain, LlamaIndex, and other AI frameworks
- Optimized performance with hardware acceleration (CUDA, Metal)
