Hello guys, I’m back again.

Yes, H3 is a single-stream Transformer, just as MiniMax described. That is great news because it is much, much, much easier to port.

**H3 support in Raylight**

* H3 is now supported in Raylight.
* On a single RTX 2000 Ada, roughly comparable to an RTX 4060, generation time dropped from 65 seconds to 35 seconds.
* Test configuration: 864 × 480 resolution, 5-second video with audio.
* FSDP support for H3 is still in progress because of an issue with the AdaLN layers.

**Other updates**

* \[Beta\] Distributed VAE, which is especially useful for heavy VAEs such as those in LTX 2.3, H3, and Wan 2.2 5B.
* More model configuration nodes now have parity with ComfyUI.
* \[Beta\] INT8 ConvRot FSDP
* \[Beta\] MXFP8 FSDP
* Non-FSDP mode can now piggyback on Aimdo for VRAM offloading. This can be disabled using the same ComfyUI CLI flag.
* Some arguments are now passed down to RayWorker.
* Added options to skip the communication test and use mmap model loading.
