May 2026 update of LCO-Embedding models

It's been a while since we introduced LCO-Embedding 3B & 7B in Oct 2025. Now we release a small update LCO-Embedding-Omni-3B-2605!

In this version, we make substantial improvements on all 4 modalities (text, image, audio, video).

Main Benchmarks (text, image, audio):

All inference code is the same with our OG models and can seamlessly support the new checkpoint by changing the model name.
