Explanation of INT8 ConvRot (FP8 is no longer needed)
The INT8 ConvRot quantization method has emerged as a new standard for 8-bit AI model storage, offering performance improvements over previous FP8 formats. This method is gaining traction for its efficiency on various NVIDIA GeForce RTX series GPUs.
Why it matters
Optimized quantization methods are critical for running high-performance AI models on consumer-grade hardware, lowering the barrier to entry for local AI deployment.
The modeling and quantization method called INT8 ConvRot , which was natively supported in ComfyUI v0.27.0 released on July 1, 2026, is a hot topic. It is particularly beneficial for the GeForce RTX 20/30 series, but it has also been reported to provide performance exceeding the previously standard FP8 and FP8 Scaled formats on the GeForce RTX 40/50 series as well. Because of this, it is said that INT8 ConvRot will become the standard for all 8-bit quantized models , and support is actually being advanced by Comfy-Org.
