Do I still need a GPU?

Performance depends on model size and hardware. Small models can run on CPU; larger ones typically need a local GPU or enough RAM.

Is this the same as ChatGPT offline?

They run open-weight models you download. Capability and safety filters follow the model, not OpenAI’s hosted stack.

Is Jan open source, and which licence applies?

Yes for the application code, but the licence changed between versions. Reading each tagged LICENSE file directly: v0.5.16 and v0.5.17 are AGPL-3.0, while v0.5.18-rc1-beta and v0.6.0 are Apache-2.0. Write-ups that give Jan a single licence usually cite one of these versions, which is why they disagree. The repository licence covers the Jan application code; the model weights you download are separate works under their own upstream terms.

How to use a comparison

  1. Start from the task, not the brand: filter the index by what you need to get done.
  2. Check the evidence: a value marked “verified” names the source page and the date it was checked.
  3. Prefer the vendor’s own page for the final decision: prices and limits change without notice.
