Comfy Blog7070Using the FastVideo FastH3 V2 checkpoint, it generates 15-second 448×256 resolution video on a single RTX 5090 GPU through optimizations like four-step sampling, sparse attention, small text encoders, small checkpoints, and fused FP4 MLP. VRAM requirements are reduced from 80GB to <30GB; this custom Comfy node is open-sourced and can be deployed by requesting GPU and models via Comfy API.
OpenAI NewsPollo AI helps creators turn bold ideas into detailed images and cinematic video ads using GPT-5.6, GPT-6 Astra, and GPT‑Image‑2.5
Ars Technica · AI6565Art Studio launches a suite of 7 open-source applications, mimicking Adobe Photoshop, Illustrator, etc., developed using Anthropic Claude Opus 5.5 and Rust, promising to reach Adobe's feature level in the future.
Amazon ScienceReactor and Amazon Neuron Science jointly optimize the Rolling Forcing model to achieve real-time video generation on Trainium, which combines the sequence prediction of large language models with the iterative optimization of diffusion models, running at 16 FPS standard video frame rate, generating 30-second high-quality videos through Rolling Forcing technology, and achieving low latency, high-efficiency real-time video generation on Trainium.
MiniMax NewsMiniMax has released the H3 model, supporting unified context understanding for text, images, video, and audio, capable of generating 2K resolution video with native stereophonic sound (up to 15 seconds long).
MiniMax · Hugging Face new modelsMiniMax-H3 is a general multimodal generation system that supports unified understanding of text, images, video, and audio, capable of generating video with up to 2K resolution and up to 15 seconds of stereoscopic audio. Its H3-Context-IR module is used for deep understanding of input commands and converting them into an intermediate representation understandable by H3-Base, but it is not open source. The H3-Base and H3-Regenerate-2K modules are responsible for audio and video generation at 768p and 2K resolutions, respectively; the former is open source, while the latter requires API calls.
Meta AI BlogMeta AI has released its most advanced image generation model, Muse Image, which can faithfully follow instructions, accurately edit, compose from multiple references, and has the ability to use agent tools, integrated with Muse Spark; Muse Video is also based on the same pre-training foundation, providing excellent visual fidelity and supporting native audio.
