Visual AI
Image Harmonization and Compositing
Image harmonization automatically adjusts a pasted foreground object so its color, lighting, and tone match the new background, making composites look real.
Visual AISDXL and Cascaded Diffusion
SDXL is Stability AI's high-resolution text-to-image model that pairs a powerful base generator with a refiner, while cascaded diffusion chains multiple…
Visual AIGLIGEN Grounded Generation
GLIGEN (Grounded-Language-to-Image Generation) lets you control exactly where objects appear in a generated image by feeding the model bounding boxes…
Visual AIT2I-Adapter for Multi-Conditional Diffusion Control
Learn T2I-Adapter for multi-conditional diffusion control: how it steers Stable Diffusion with edges, depth, pose, and other conditions using a lightweight…
Visual AINull-Text Inversion
Null-text inversion is a technique that lets you edit a real photo with a text-driven diffusion model like Stable Diffusion while keeping everything you…
Visual AICustom Diffusion Multi-Concept Tuning
Custom Diffusion is a lightweight fine-tuning method that teaches a text-to-image model new personal concepts, like your dog or a specific chair, from just…
Visual AILatent Blending and Image Interpolation
Latent blending mixes images by combining their compressed representations inside a model's latent space rather than averaging raw pixels.
Visual AIVision-Language-Action Models for Robotics
Vision-Language-Action (VLA) models are large neural networks that take in camera images plus a written instruction and directly output robot motor commands.
Visual AIDiffusion Policy for Robot Control
Diffusion Policy applies the same denoising idea behind image generators like Stable Diffusion to robot control: instead of predicting a single next action…
Visual AIMake-A-Video Text-to-Video
Make-A-Video is Meta's 2022 system that turns a text prompt into a short video clip without ever training on labeled text-video pairs.
Visual AIImagen Video Cascades
Imagen Video is Google's 2022 text-to-video system that builds a clip through a cascade of seven diffusion models, each adding more frames or more resolution.
Visual AICogVideo and CogVideoX
CogVideo (2022) was the first large-scale open text-to-video model, and CogVideoX (2024) is its far more capable open-source successor from Tsinghua/Zhipu AI.
