Model weights: Apache License 2.0. Original Gemma 4 E2B instruction-tuned model
Copyright Google; https://huggingface.co/google/gemma-4-E2B-it
Original weights are redistributed unchanged. The unmodified Q4 GGUF is from
https://huggingface.co/unsloth/gemma-4-E2B-it-GGUF (Apache-2.0).
The compatible mmproj is an external download from that upstream repository;
it is not redistributed in this package. Google provides the original weights.
Modified artifacts: mixed-precision quantization, QNN compilation, intermediate
feature outputs, portable vision-embedding operator alias, CPU drafter training
and packaging. These are independent preparations, not official Google,
Qualcomm, Unsloth or Z Lab releases. Detailed source revisions and changes are
recorded in provenance.json and quantization.json.
DFlash2-derived grouped dynamic-convolution/selection components are based on
