TextME: Bridging Unseen Modalities Through Text Descriptions

Official projection checkpoints and offset vectors for TextME, a text-only modality expansion framework that projects diverse modalities into LLM embedding space without paired cross-modal data.

Model Description

TextME trains lightweight projection heads (2-layer MLP, ~10M params each) to map pretrained encoder embeddings into a unified Qwen3-Embedding-4B anchor space (2560-dim). Training uses only text descriptions — no paired multimodal data is needed.
