diffusion model

Alibaba's Qwen team has open-sourced Qwen-Image-2.1, a 7B parameter unified model for text-to-image generation and image editing. The release adds native transparent (RGBA) image support and editing with up to 10 reference images.

Lightricks has released LTX-2.5, an open-weight world model that generates synchronized video and audio from text, image, and video inputs. The 22B-parameter model adds native multishot generation, a new diffusion video decoder, and a custom Gemma4 12B text encoder.

Microsoft has released Mage-Flow, a 4B-parameter open-weight foundation model for text-to-image generation and instruction-based editing. The company claims it matches or beats much larger open systems like Qwen-Image (20B) and FLUX.2 (32B) while running faster and using less memory.
