## In short

ComfyUI v0.35.0 introduces the Comfy Compiler and adds nodes for OpenAI GPT-6 Astra, GPT Image 2.5, Claude Fable 5.1, Google Omni 1.1 and Meta Muse Image. A File3DToMesh node parses GLB, GLTF, OBJ and STL files into meshes.

## What it is

The Comfy Compiler arrives in ComfyUI v0.35.0, alongside partner nodes for OpenAI GPT-6 Astra and GPT Image 2.5, Claude Fable 5.1, Google Omni 1.1, MiniMax-H3 Max Turbo, Recraft V4 Styles Pro and Meta Muse Image. On the 3D side, a File3DToMesh node parses GLB, GLTF, OBJ and STL files into a MESH, and Pixal3D multiview models are supported.

## How it works

The release notes describe the compiler through its guardrails rather than its design — it pauses for long-lived sparse allocations, and several fixes in this version target memory handling. The rest of the update is node work: VideoTrim and VideoCrop gain editing widgets, Save Image Advanced writes AVIF, HEVC remuxing to MP4 and MOV improves, and PyTorch SDPA attention is enabled on more AMD GPUs.

## Why it matters

ComfyUI is where much open-source image and video work actually runs, so how quickly a new model gets a node decides how fast it reaches those graphs. This release also cleans up alpha-channel handling across several nodes, adds Porter-Duff blend modes with transparency and a colour-space conversion node, and improves memory management for container deployments.
