This page contains fp8 quantized DiT models of Neta Lumina for ComfyUI.

• Neta Lumina (NT)

• NetaYume Lumina (NTYM)

And a fp8 quantized Gemma 2 2b (the text encoder).

Update (11/27/2025): mixed precision and fp8 tensor core support (mptc).

This is a new ComfyUI feature that supports fp8 tensor core, also with mixed precision.

In short:

Mixed precision: Keep important layers in BF16.

FP8 tensor core support: On supported GPU, much faster (30~80%) than BF16 and classic FP8 scaled models. Because ComfyUI will do calculations in FP8 directly, instead of dequantizing + BF16. torch.compile is recommended.
