Attention! Newly Added Latest Models (Partner Nodes)
The most noteworthy part of this update is the newly supported 'partner nodes.' This makes it possible to handle the following latest models on ComfyUI.
Specifically, the following models were added: - FLUX 3 Image (image generation model) - Sonnet 5.5 (Anthropic's model) - Ideogram 4.5 (image generation model) - HeyGen Video 1.0 (video generation model) - grok-imagine-video-1.5-lite (Grok's video generation model)
For those who want to try the FLUX series or the latest Ideogram, this is a very significant update.
- Added support for Sonnet 5.5 model
- Added nodes for Ideogram 4.5 model
- Added support for HeyGen Video 1.0 model
Improvements in Video Generation and Export Quality
Improvements regarding 'output quality,' which is crucial in creative production, are also included.
First, the default encoding quality for the 'Save Video' function when saving videos has been improved. This allows you to obtain higher-quality videos without having to be particularly conscious of it.
Additionally, 16-bit float support was added for 'Save EXR (high dynamic range image format).' This is a mechanism that preserves color gradations more accurately, making it an important update for those aiming for professional-grade advanced editing work.
- Save Video: Improved default quality
- Save EXR: 16-bit float support
- Enhanced support for Minimax H3 related issues (fixes for VAE offloading problems, etc.)
Improvements in Operability and Convenience
Changes have also been made to increase the flexibility of the user interface and the system.
Input for 'DynamicGroup widgets (input items that dynamically manage groups)' has been newly added, making workflow construction smoother. Furthermore, fixes such as error corrections regarding model category scanning are included, contributing to improved system stability.
Moreover, it is now possible to control the behavior of partner nodes and API nodes via command line arguments. For example, by using options such as '--offline' or '--disable-partner-nodes,' flexible settings can be made according to your environment.
- Addition of --offline and --disable-partner-nodes
- Support for DynamicGroup widget input
- Update of ComfyUI frontend package (1.53.10)
Summary: What You Can Do with This Update
The v0.39.0 update establishes a foundation for handling the latest trends, such as 'FLUX-based models' and 'high-quality video generation,' more stably and at a higher level.
For those who mainly perform video production or want to try the latest models as soon as possible, this can be called an essential update. Please try utilizing the new features while reviewing your node settings according to your own environment.
- Support for latest models (FLUX 3 / Ideogram 4.5, etc.)
