Comfy Worker (ARM64 RTX) Release Notes

This Comfy Worker image is for Linux ARM64 hosts with a discrete NVIDIA Blackwell GPU (SM120). It has its own version numbers and updates, separate from the x86 worker and DGX Spark worker.

#Requirements

On a machine with both integrated and discrete graphics, assign the supported discrete GPU explicitly. The Thor integrated GPU is a different architecture and cannot run this image. A DGX Spark uses its separate Spark image.

This release was qualified with Z-Image Turbo, FastH3 text-to-video, image-to-video and first/last-frame video, BiRefNet background removal, and SAM 3 segmentation. Native ARM64 GPUs with 32 GB have not been qualified.

The worker checks the live catalog, available dependencies, GPU memory, host RAM and installed models before advertising work. ARM64 currently excludes Wan Animate, LTX aggregate video editing, RTX VSR, FlashVSR and legacy Stable Diffusion / ControlNet workflows.

#Updating

The installer selects sogni/comfy-worker-arm64-sm120:latest on a qualifying ARM64 machine. Run ./worker-restart.sh from the installer folder, or use Upgrade worker in the Dashboard. Wait for active work to finish. A deployment pinned to an exact version keeps that pin until its operator changes it.

Model files remain in the persistent model cache across ordinary worker image updates. A new host must download its selected models and needs storage for those files, Docker layers and temporary downloads.

#Version 1.0.2026102601

Released: October 27, 2026 PT · Update: Initial release for qualifying ARM64 RTX hosts.

• Runs Comfy image and video workloads on Linux ARM64 with a discrete Blackwell GPU.
• Includes FastH3 video from text, a source still, or endpoint stills, with sound and two-stage refinement.
• Updates independently of the x86 and DGX Spark worker images.

Disk and settings: Use installer 1.0.182 or newer and persistent model storage. Mixed integrated/discrete hosts need an explicit supported GPU assignment.
