Excited to open-source faster building blocks, like decoders, to make video generation more efficient. The ultimate goal is to make state-of-the-art technology more accessible to everyone!

Today, we open-source PrunaVAED, a faster drop-in replacement decoder for video generation with LTX-2.3! - 𝗛𝗼𝘄 𝗲𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝘁 𝗶𝘀 𝗶𝘁? ~1.7-2.1x faster decoder & ~50% lower peak VRAM - 𝗛𝗼𝘄 𝗴𝗼𝗼𝗱 𝗶𝘀 𝗶𝘁? Near-original visual quality & no changes to the latent

In seconds, turn high-tech product photos shots into clean, marketplace-ready packshots while keeping the exact device, casing, and screen unchanged. What’s the setup? 👀 - Model: P-Image-Edit - Input image: Use a real product photo from a listing or device catalog - Input prompt: Remove the existing background and place the exact same device on a clean white or studio backdrop, while preserving its model, casing, screen, and details This makes it possible to standardize product images consistently and at scale across marketplaces and product detail pages, without reshooting every item. 👉 Try it for free: …ground-production-861e.up.railway.app 📚 Read our documentation: docs.pruna.ai 🧩 Sign up here: dashboard.pruna.ai
