You can see what it uses here - https://github.com/ente-io/ente/blob/main/web/apps/ensu/src/...
Either LFM2.5-1.6B-4bit or Qwen3.5-2B-8bit or Qwen3.5-4B-4bit
Huh, 1.6B/2B/4B models, I guess they weren't joking when they said "not as powerful as ChatGPT or Claude Code". Also unsure why they said "Claude Code", it's not an CLI agent AFAIK?
Hmm, the Mac app downloaded gemma-3-4b-it-Q4_K_M.gguf for me (on an Apple M4) - maybe the desktop apps download different models?
Though, I don't see any references to Gemma at all in the open source code...
