## Choose when

### Choose PiSSA if…

- PiSSA is primarily Jupyter Notebook; ollama is Go.
- Tags unique to PiSSA: fine-tuning, jupyter notebook, quantization, peft.
- Also covers Vector Databases.

### Choose ollama if…

- ollama is primarily Go; PiSSA is Jupyter Notebook.
- Ollama supports self-hosted and cloud-deployable models using Docker, Helm charts, and various package managers.
- Tags unique to ollama: go, llms, llama, mistral.
- ollama ships Docker support for self-hosted deployment.
- Use Ollama when you require a multi-model platform supporting several large language models such as Kimi-K2.6, GLM-5.1, MiniMax, DeepSeek, gpt-oss, Qwen, Gemma and intend to deploy in various cloud or

## When NOT to use PiSSA

- Last GitHub push was 377 days ago (dormant maintenance, Jun 30, 2025). Validate activity before betting a new project on PiSSA.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.

## When NOT to use ollama

- Avoid using Ollama if you are only interested in a single LLM deployment and seek simplified, model-specific solutions with tailored support rather than a comprehensive multi-model platform.
