Clever Design & Architecture: Efficiency at Its Best
The architecture of LFM2VL is thoughtfully crafted to maximize speed without compromising accuracy:
Three main components:
A language model backbone, based on prior models like LFM21.2B for the larger version, and LFM2350M for the smaller.
A vision encoder, utilizing SIGLIP 2 NLEX encoders—faithful to the original images processed at their native resolution (up to 512x512 pixels) without unnecessary resizing or distortion.
A multimodal projector, which elegantly merges visual and textual data using a technique called pixel unshuffle, effectively reducing image tokens and focusing computational effort on meaningful details.
