Open source: what people are building this week

3-5 trending open-source AI image and video projects, picked each Monday from GitHub and Hugging Face Models.

Week of 21 September 2026

This week's picks center on reducing pipeline steps: unified architectures, quantized local models, and agentic orchestration handle more in fewer passes.

    Qwen· 1,250 likes

    Qwen-Image-2.1 is a 7B-parameter diffusers-compatible model that handles text-to-image generation, image editing, and RGBA/transparent layer output within a single unified architecture. Builders working on compositing pipelines or subject extraction workflows may find the native transparency support particularly useful, since it removes the need for a separate matting or segmentation step.

    Wan2.2GitHub

    Wan-Video· 17,580 stars

    Wan2.2 is an open-source collection of large-scale video generation models from the Wan-Video team, supporting text-to-video and image-to-video synthesis. Builders looking to run or fine-tune capable video generation models locally will find production-ready Python code along with model weights they can work with directly.

    GGUF quantizations of Qwen/Qwen-Image-2.1 packaged for local text-to-image generation, with variants ranging from Q4_0 (4.05 GB) to Q8_0 (7.59 GB) and companion text encoder and VAE files formatted for ComfyUI. Builders running ComfyUI locally who want a ready-to-use quantized pipeline without manual conversion work will find the prepackaged file set a practical starting point.

    FastVideo· 85 likes

    FastVideo-FastH3-8-Step-V2 generates synchronized video and audio from a text prompt in just eight transformer forward passes, using a DMD2-distilled VSA-H3 sparse attention backend at 80% sparsity. Builders looking to reduce inference cost on video generation tasks without a separate audio pipeline may find the joint video-audio output and low step count worth evaluating.

    hypitGitHub

    hypit-ai· 12,483 stars

    **hypit-ai/hypit** takes an existing viral video and uses AI agents to systematically replace its face, voiceover, and B-roll footage, outputting large batches of variants in a single command. Builders experimenting with agentic video pipelines may find the DSL and compiler layer worth examining as a pattern for orchestrating multi-step generative workflows at scale.
