LLaVA and Visual Instruction Tuning
LLaVA (April 2023) is the most copied multimodal architecture on the planet. It replaced BLIP-2's Q-Former with a 2-layer MLP, replaced Flamingo's gated cross-attention with naive token concatenation, and trained on 158k visual-instruction turns generated by GPT-4 from text-only captions. Any practitioner who built a VLM between 2023 and 2026 built some variant of LLaVA. LLaVA-1.5 added AnyRes. LLaVA-NeXT bumped resolution. LLaVA-OneVision unified image, multi-image, and video in one recipe. This lesson reads the recipe, implements the projector, and explains why "simpler won."

It is part of the curriculum and will get the same treatment as Phase 1 — a visual cover, hands-on labs, derivations with numeric checks and a quiz. Until then, the original lesson is the best place to read it:
