🎬 MAGI-1: Китайский ИИ для генерации видео с точностью до секунды

Компания Sand AI представила революционную модель для создания видео — MAGI-1. Это первый в мире авторегрессионный видеогенератор с контролем времени на уровне секунд. На GitHub проект за сутки собрал уже более 1k звезд.

🔹 Почему это важно?
MAGI-1 преодолевает ключевые проблемы AI-видео: рваные переходы, неестественные движения и ограниченную длину роликов.

📌 Ключевые особенности:
✔Бесконечное продолжение — создает плавные длинные сцены без склеек
✔Точный контроль времени — можно задать действия для каждой секунды
✔Естественная динамика — движения выглядят живо и реалистично
✔8K-качество — сверхчеткое изображение

🛠 Технические детали:
- Архитектура: VAE + Transformer (сжатие 8x пространственное, 4x временное)
- Метод: авторегрессивная дениойзинг-диффузия по блокам (24 кадра)
- Инновации: causal attention, QK-Norm, GQA, SwiGLU
- Размеры моделей: 24B и 4.5B параметров
💡 Почему это прорыв?
1. Открытый доступ (веса + код)
2. Работает даже на RTX 4090
3. В 2.6× эффективнее аналогов (MFU 58%)
4. Лидер VBench-I2V (89.28 баллов)

Основатели проекта — звезды AI-исследований:
👨💻 Цао Юэ (эксперт CNN, 60k цитирований)
👨💻 Чжан Чжэн (соавтор Swin Transformer)

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences.
