Choose jan if…

- Tags unique to jan: chatgpt, gpt, llamacpp, localai.

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.

Choose Ollamac if…
- Ollamac is primarily Swift; jan is TypeScript.
- Tags unique to Ollamac: ai, llama3, llma, llma2.

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.

- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
