## Choose when

### Choose jan if…

- jan is primarily TypeScript; Ollamac is Swift.
- Tags unique to jan: chatgpt, gpt, llamacpp, localai.
- - If you require an offline-capable AI assistant for environments without internet access.

### Choose Ollamac if…

- Tags unique to Ollamac: ai, llama3, llma, llma2.

## When NOT to use jan

- - If you require real-time updates to the AI model, since Jan uses static local models which may not get frequent updates.
- - When a vast knowledge base or continuous learning capabilities are essential, as Jan's offline nature constrains its ability to stay current with new information.

## When NOT to use Ollamac

- Last GitHub push was 489 days ago (dormant maintenance, Mar 12, 2025). Validate activity before betting a new project on Ollamac.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
