# Lexi

Context-aware personal phonetic memory demonstration.

This Space hosts the live Lexi application and the Evaluation Lab. The Evaluation Lab exposes only **Auto**. The uploaded CSV describes the user's journey and expected behavior; Lexi decides whether to resolve a case locally, with semantic ML retrieval, or with a rare Gemini ambiguity check.

## Secrets

Set `GEMINI_API_KEY` in the Space Secrets to enable the optional Gemini ambiguity resolver. The app remains usable without the key.

## ZeroGPU

The Space is designed for ZeroGPU. MiniLM semantic retrieval is invoked only when the local contextual path is insufficient. A lightweight local fallback keeps the app usable if semantic model initialization is unavailable.
