    KromaHF Models

    lodestones· 148 likes

    Kroma is a LoRA fine-tune for Krea 2, distributed as a single ComfyUI-compatible safetensors file that combines 264 low-rank adapters (rank 256) with full weight deltas for RMSNorm and modulation tensors to faithfully reproduce the fine-tuned behavior. Builders who already run Krea 2 in ComfyUI can drop this into their existing loras folder and load it via the standard LoraLoader node without any custom code or format handling.

    PrunaVAEDHF Models

    PrunaAI· 59 likes

    PrunaVAED is a pruned VAE decoder component built on the LTX 2.3 architecture, designed for text-to-video pipelines using the diffusers library. Builders looking to reduce inference overhead in LTX-based video generation workflows may find it a practical drop-in replacement for the standard decoder.

    YouMind-OpenLab· 9,089 stars

    A curated, daily-updated library of 2,000+ prompts for OpenAI's GPT Image 2 model, organized with preview images and support for 16 languages. Builders exploring the model's text rendering or cross-image consistency capabilities can use it as a reference for what kinds of prompts reliably produce production-quality results.

    ABot-World-0-5B-LF is a 0.5B-parameter image-to-video world model built on the diffusers library that generates interactive video rollouts from a single input image. Builders working on interactive or game-like environments may find it worth evaluating given its stated ability to run on a single desktop GPU, which lowers the infrastructure bar for local experimentation.

    LykosAI· 8,587 stars

    StabilityMatrix is a cross-platform package manager that handles installation and management of popular Stable Diffusion interfaces, including Automatic1111's sd-webui and ComfyUI. Builders who want to run multiple inference backends side by side without manual Python environment conflicts will find the unified launcher useful.
