    “Windows Subsystem for Linux” is probably the most confusing example of this (an environment subsystem which provides a Linux userspace to a Windows NT kernel). more intuitive woul…

    I think they meant scrollback. as conventionally a backlog would evoke "work yet to be done", whereas in this context we're talking about a conversation history one can revisit.

    > Is it super resolution? nope, we don't do Imagen-style super-resolution. we go direct to high resolution with a single-stage model.

    FID doesn't reward high-resolution detail. the inception feature size is 299x299! so we are forced to downsample our FFHQ-1024 samples to compute FID. it also doesn't punish poor d…

    the FFHQ-1024 examples shouldn't be blurry. you can download the originals from the project page[0] — click any image in the teaser, or download our 50k samples. the ImageNet-256 e…

    cross-attention doesn't need to involve NATTEN. there's no neighbourhood involved because it's not self-attention. so you can do it the stable-diffusion way: after self-attention, …

    ah, originally lstein/stable-diffusion? yeah that was an important fork for us Mac users in the early days. I have to confess I've still never used a UI. :) this year I'm hoping fo…

    regarding ControlNet: we have a UNet backbone, so the idea of "make trainable copies of the encoder blocks" sounds possible. the other part, "use a zero-inited dense layer to proje…

    I'm one of the authors; happy to answer questions. this arch is of course nice for high-resolution synthesis, but there's some other cool stuff worth mentioning.. activations are s…

    Most things require workarounds, some things aren't possible (or we haven't found workaround yet) and it's not as fast as CUDA. But stable-diffusion inference works, and so does te…

    It's probably the same thing prestodb encountered: https://github.com/prestodb/presto/issues/8993

    For performance reasons, glibc may not return freed memory to the OS. You can increase the incentive for it to do so, by reducing MALLOC_ARENA_MAX to 2. https://github.com/prestodb…

    stable-diffusion supports k-diffusion just fine on M1. You just have to detach a tensor in to_d() to stop the values exploding to infinity. https://twitter.com/Birchlabs/status/156…

    9.3 secs if you sample for 7 steps. 11 secs if you sample for 8 steps. Heun sampler, M1 Max. https://twitter.com/Birchlabs/status/1564792349221330944?s=2...

    Comment #32687655

    Neither of these should take minutes. Try Heun sampler, 8 steps, Karras noise schedule. Should be possible to get good images in 11 secs (or 10 secs if you go down to 7 steps). mea…

    About 10 secs per image on M1 Max with the right noise schedule and sampler. https://twitter.com/Birchlabs/status/1565029734865584143?s=2...

    yes, that demo has very impressive shaders. it models the physics in a more simple way though (i.e. as waves), rather than as thousands of particles, so it can't generalize to more…

    network inspector says 2.1MB. but that's dominated by a 1.3MB image. the main assets of the library are: - Box2D.simd.js (422kB) - Box2D.simd.wasm (266 kB) a minimal demo that uses…

    it's all modelled using physical laws; see slides 16 onwards of the "Inside Liquidfun" presentation: http://docs.google.com/presentation/d/1fEAb4-lSyqxlVGNPog3G1...

    okay, have another look now[0]. I've updated it to use a consistent number of particle iterations regardless of how much time is being simulated. in fact, you've caught that it was…
