What it is useful for
Run and use notes
- The installation guide states that Diffusers sends telemetry (library versions, the requested model or pipeline class, and the Hub checkpoint path) when loading from the Hub, not for local files, and that it can be turned off with HF_HUB_DISABLE_TELEMETRY=1. Offline use is possible with HF_HUB_OFFLINE=1 once files are cached.5
Organization context
In the news
Diffusers 0.41.0 adds a Qwen-Image 2.1 pipeline and deprecates ONNX support
On October 6, 2026 Hugging Face published Diffusers 0.41.0 on GitHub. The release notes say it adds Qwen-Image 2.1, with text-to-image generation, image editing, native transparency, and LoRA training, and introduces tensor-parallel checkpoint loading in which each rank reads its own slice of sharded weights. The notes deprecate ONNX support in favor of Optimum and remove previously deprecated APIs, including the
LuminaText2ImgPipelineandLumina2Text2ImgPipelinealiases. They also say minor releases will now be coordinated around new model integrations, as in Transformers. Qwen-Image 2.1 is a third-party model and is not a catalog entry; the notes do not state its license.
