TEG (Trimodal Embeddings Gemma) maps image, audio, and text into a shared 768-dim embedding space via Google's embeddinggemma-300M, with Matryoshka truncation support down to 128 dims.

Available quantizations

File	Quant	Size	Description
`teg-421m-q8_0.gguf`	Q8_0	501 MB	8-bit — minimal quality loss
`teg-421m-q5_0.gguf`	Q5_0	408 MB	5-bit — good balance of size and quality
`teg-421m-q4_1.gguf`	Q4_1	390 MB	4-bit with offsets — best for constrained devices

All variants use per-component quantization: Gemma text model gets the target quant, image/audio encoders stay at Q8_0, and projection heads stay at F16 to preserve retrieval quality.
