Sora is OpenAI’s advanced text-to-video generation model that takes text, images, or short video inputs and produces new videos up to 20 seconds long (1080p, vertical or horizontal format). It also supports remixing or extending existing video clips and blending media inputs. Sora is accessible via ChatGPT Plus/Pro and through a web interface. The system includes a featured/recent feed showcasing community creations. It embeds strong content policies to restrict sensitive or copyrighted content, and videos generated include metadata tags to indicate AI provenance. With the announcement of Sora 2, OpenAI is pushing the next iteration: Sora 2 is being released with enhancements in physical realism, controllability, audio generation (speech and sound effects), and deeper expressivity. Alongside Sora 2, OpenAI launched a standalone iOS app called Sora, which resembles a short-video social experience.

Wan2.2 is a major upgrade to the Wan suite of open video foundation models, introducing a Mixture‑of‑Experts (MoE) architecture that splits the diffusion denoising process across high‑noise and low‑noise expert paths to dramatically increase model capacity without raising inference cost. It harnesses meticulously labeled aesthetic data, covering lighting, composition, contrast, and color tone, to enable precise, controllable cinematic‑style video generation. Trained on over 65 % more images and 83 % more videos than its predecessor, Wan2.2 delivers top performance in motion, semantic, and aesthetic generalization. The release includes a compact, high‑compression TI2V‑5B model built on an advanced VAE with a 16×16×4 compression ratio, capable of text‑to‑video and image‑to‑video synthesis at 720p/24 fps on consumer GPUs such as the RTX 4090. Prebuilt checkpoints for T2V‑A14B, I2V‑A14B, and TI2V‑5B stack enable seamless integration.
