A vision encoder is a necessary component for allowing many leading LLMs to be able to work with images uploaded by users.

Hugging Face Inc. today open-sourced SmolVLM-256M, a new vision language model with the ... SmolVLM-256M’s encoder is based on an open-source AI called SigLIP base patch-16/512.

LLaVA 1.5 improves upon the original by connecting the language model and vision encoder through a multi-layer perceptron (MLP), a simple deep learning model where all neurons are fully connected.

Google claims that Gemma 3 is the "world's best single-accelerator model," outperforming competitors ... Gemma 3 packs an upgraded vision encoder that handles high-res and non-square images ...

It employs a vision transformer encoder alongside a large language model (LLM). The vision encoder converts images into tokens, which an attention-based extractor then aligns with the LLM.
