# System 1 + 2

Most chat messages don't need a large language model. Here, every message is first matched against your memories (notes, photos and voice memos stuck to a fridge) with **EmbeddingGemma 2**. Then **Strands Decider 2B**, a System One decision model run with [open-jev](https://github.com/nico-martin/open-jev), decides whether one of those memories already answers it. If one does, the answer is the memory itself, in a few hundred milliseconds. If not, **Gemma 4 E2B** writes the answer, with the closest memories as context. A meter counts how often Gemma was actually needed.

- Drop photos or voice memos on the fridge: Gemma 4 describes each one once, then it's searchable.
- "How it decided" shows exactly what System One read: memories with match strength in words, never scores.
- "Still ask Gemma" puts the memory answer and Gemma's answer side by side.
- Everything runs in your browser on WebGPU (about 4.5 GB of models on first load, cached after). On phones the memory route runs with the 345 MB GLiNER2.5-Decide mobile build; Gemma 4 needs a desktop.
