11.0 Introduction
Multimodal Large Language Models (MLLM)
The structure of typical Multimodal Large Language Models (MLLM) can be divided into:
- Pre-trained Modality Encoder: Encode data such as images, audio, video, point clouds, etc, into latent features.
- Pre-trained Large Language Model: Understands and reasons about encoded text and multimodal data.
- Modality Connector: Aligns different modalities.
- Modality Generator: Outputs multimodal information other than text.
There are three types of modality connectors according to the survey:
- Projection-based (token-level): via, for example, MLP layers.
- Query-based (token-level): like Q-Former
- Module-based (feature-level): via, for example, cross-attention layers
Vision Language Models (VLM)
Here we focus on the image part of the VLM. Below is the overall evolution path of image encoders. And here is the image encoders some VLMs are using:
- Gemma3: SigLIP
- Qwen2.5-VL: ViT
- InternVL2.5: ViT
- LLaVA-1.5: CLIP
- LLaMA-3.2-Vision: CLIP
