LLM Chronicles #6.3: Multi-Modal LLMs for Image, Sound and Video

In this episode we look at the architecture and training of multi-modal LLMs. After that, we’ll focus on vision and explore Vision Transformers and how they are trained with contrastive learning (OpenAI's CLIP and Google's SigLIP). Vision Transformers are the most commonly used building block in MLLMs with vision capabilities. Finally, we’ll get hands-on and look into Google’s open-weight PaliGemma, analysing its implementation to see these concepts in action within a real-world multi-modal LLM.
