Local LLM Research Hub
This stack is built for private research and knowledge work. It combines Ollama, Qdrant, and Open WebUI so you can index documents locally and query them with a local LLM.
What you get
- Private document search and question answering
- Local RAG (retrieval augmented generation) without cloud services
- A research hub for notes, reports, and private knowledge
Architecture
| Component | Role |
|---|---|
| Ollama | Serves the local model |
| Qdrant | Stores embeddings and document vectors |
| Open WebUI | Browser interface for queries |
| Qwen 3.14B | Model for research and retrieval |
Prerequisites
- A CUDA GPU such as RTX 4080
- Document source files and enough disk for vectors
- Python or CLI tools to create embeddings and load Qdrant
Setup
- Install Ollama, Qdrant, and Open WebUI.
brew install ollama
docker pull qdrant/qdrant- Start Qdrant.
docker run -d --name qdrant -p 6333:6333 qdrant/qdrant- Pull the local model.
ollama pull qwen3:14b
ollama serve-
Index documents into Qdrant using your preferred embedding pipeline.
-
Open the browser UI and connect it to Ollama and Qdrant.
Use it
- Private research for internal reports, proposals, and technical knowledge.
- Q&A on documents without sending text to a cloud provider.
- Team knowledge base for secure local access.
Cost vs cloud
| Local | Cloud | |
|---|---|---|
| Monthly | $0 | $20+ per seat |
| Hardware | $2000 once | $0 |
| Privacy | High | Low |
Troubleshooting
- Qdrant connection fails → check port 6333 and network settings.
- Embedding quality low → use better local embeddings or a stronger model.
- Ollama not serving → verify
ollama psand local API.
Swap components
- Use Open Interpreter for command-style research workflows.
- Use Gemma 4 12B if you need a stronger multimodal model.
