Xiaomi-Lens-0

Xiaomi released Xiaomi-Lens-0, a 4B multimodal model built on Qwen3.5 that predicts segmentation masks from its own visual representations and gains 5.6 points on RefCOCO over Qwen3.5.

A lightweight decoder combines vision-encoder patch features with visual latents, which are the language model's mask-token states. Mask supervision therefore reaches the shared backbone without a separate segmentation encoder. Each latent decodes to a mask, so the model can interleave reasoning with region-specific latents, and grounded reasoning traces supervise the regions it visits during chain-of-thought.
