Multi-Agent Reinforcement Learning (MARL) trains several learning agents that share an environment, each adapting its behavior while the others adapt too.
Language AIBeam search is a decoding strategy that keeps the several most promising partial sequences at each step instead of greedily committing to one.
Language AINucleus (top-p) and top-k sampling are decoding methods that add controlled randomness to text generation by restricting which tokens can be chosen.
Visual AIAutoregressive image generation builds pictures one piece at a time, predicting each token from everything generated before it.
Visual AIVQ-VAE compresses images, audio, or video into a small grid of discrete codes drawn from a learned codebook, instead of continuous numbers.
Visual AIThe Segment Anything Model (SAM) is Meta AI's foundation model for image segmentation: given a point, box, or rough hint, it instantly outlines…
CompaniesStability AI is the London-based startup behind Stable Diffusion, the open-weight image generator that put text-to-image AI on millions of laptops.
CompaniesRunway is an applied AI research company building generative video tools that turn text and images into moving footage.
CompaniesPerplexity AI is an 'answer engine' that combines large language models with live web search to deliver direct, cited answers instead of a list of blue links.
Visual AITextual Inversion teaches an image generator a brand-new concept—like a specific cat, art style, or product—by learning a single fresh word for it, without…
Visual AIDreamBooth fine-tunes an entire image model on a handful of photos so it deeply 'remembers' a specific subject—your face, pet, or product—and can place it…
Visual AIInpainting fills in or replaces a masked region inside an image, while outpainting extends an image beyond its original borders.
