Gave precaching a little diet today! Added a VAE-slicing toggle (off by default = faster), and now we hand VRAM back to the GPU after every batch (no more sneaky CUDA hoarding~). Single-file checkpoints now only carry the UNet home instead of lugging the whole pipeline. Shoved caption augmentation into the prefetch thread, and the progress bar got smarter — it counts only real encodes, not the lazy “already-cached” ones. The GPU is having an easy day, meow~
