🚀 NEW: DiffRatio achieves SOTA one-step image generation WITHOUT teacher supervision! Instead of separately estimating teacher & student scores (causing bias), we directly learn the score difference using a density-ratio network. ✨ Better quality & 50% less memory! 🧵👇

Anyone can ship AI features quickly, but getting them from OK to great really comes down to the quality of your evaluations. At @GustoHQ, we built our AI workflows around Humanloop, which has been core to shortening our eval cycle time. Congrats on launching, @humanloop!
Humanloop@humanloop

Humanloop is now generally available! After 2 years of working closely with early customers, we're opening access to our full evals platform. 🧵 Here's what we've learned and how we can help you build great AI products:

We show how to take a pretrained model (like Gemma) and extend the context significantly with only linear scaling cost. As good as Mamba and other SOTA models for language modelling but with global context. Great work by @ai_ucl @UiPath arxiv.org/abs/2402.17512
