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!

This is a very nice piece of work, showing how to use the optimal form of the denoising covariance to improve generations.
🚀 We propose a new way to estimate the denoising covariance in diffusion models, which can lead to lower estimation error, better FID and likelihood tradeoff with fewer steps, and improved generation diversity.
