Provenance

This artifact is mirrored byte-for-byte from litert-community/gemma-4-E2B-it-litert-lm (gemma-4-E2B-it.litertlm). It is provided under Apache-2.0, as published there. The text-only GPU export the app used before this lives at latentdivergence/domain-expansion-gemma-4-e2b-mobile.

Use

Download gemma-4-E2B-it.litertlm to app-private storage. Do not package it in an APK. Initialise it lazily with LiteRT-LM using Backend.GPU() for both the decoder and visionBackend, send one encoded JPEG per turn as Content.ImageBytes, and release the engine when the companion is idle.
