| # ltpla/gemma-4-e4b-it-noaudio-4bit | |
| **This is a modified version of [`mlx-community/gemma-4-e4b-it-4bit`](https://huggingface.co/mlx-community/gemma-4-e4b-it-4bit).** The Universal Speech Model encoder (`audio_tower.*`) and audio embedder (`embed_audio.*`) — 754 weight keys, ~270 MB at 4-bit — have been removed; `config.json` has `audio_config` and `audio_token_id` dropped and `has_audio` set to `false`. The text model and vision tower are unchanged. | |
| Useful when audio input is not needed and disk/memory footprint matters (e.g. on systems with 16 GB unified memory). Audio prompts will fail at the model level — the audio tower is gone. Text-only and image inputs work exactly as the original. | |
| ## Licence | |
| Gemma is provided under and subject to Google's [**Gemma Terms of Use**](https://ai.google.dev/gemma/terms) and [**Gemma Prohibited Use Policy**](https://ai.google.dev/gemma/prohibited_use_policy). By using, modifying, or distributing this model you agree to those terms, including the prohibited-use restrictions. This work is a modification; the original Gemma 4 model card is at [google/gemma-4-e4b-it](https://huggingface.co/google/gemma-4-e4b-it). | |
| ## Modifications from base | |
| - Stripped `audio_tower.*` and `embed_audio.*` weights | |
| - Dropped `audio_config` and `audio_token_id` from `config.json` | |
| - Set `has_audio: false` | |
| - Repacked safetensors with updated `model.safetensors.index.json` | |
| ## Size | |
| - This variant: ~4.6 GB | |
| - Base (4bit): ~4.9 GB | |
| ## Use with mlx-vlm | |
| ```bash | |
| pip install -U mlx-vlm | |
| python -m mlx_vlm.generate \ | |
