A developer released a heavily modified fork of the classic Stable Diffusion WebUI tool Automatic1111 (A1111) on Reddit, bringing it up to modern standards.
- Core Upgrade: Fully ported to Python 3.14 natively, removing legacy compatibility layers and automatically resolving dependency conflicts like NumPy and SciPy.
- Model Compatibility: The first A1111 fork to fully support Pony and Illustrious SDXL models (including LoRA), solving crashes that previously forced users to switch to ComfyUI.
- Built-in Extensions: Comes pre-packaged with popular extensions like ControlNet, ADetailer, and ReActor face swap.
- Performance: Introduces direct Flash-Attention 2 support with graceful fallbacks, and supports loading new SDXL ConvRot INT8 / NVFP4 quantized checkpoints.
