What is Kandinsky 5.0？
Kandinsky 5.0 is a text-to-video generation model developed by the Russian AI research lab AI-Forever, featuring powerful generative capabilities and high-performance efficiency. Its core version, Kandinsky 5.0 Video Lite, is a lightweight model with 2 billion parameters, delivering excellent generation quality, even surpassing some larger models. The model supports multiple variants, including the SFT model (highest generation quality), CFG distillation model (approximately 2× faster inference), and Diffusion distillation model (low-latency generation with minimal quality loss), catering to different use-case scenarios.
The model uses a Flow Matching–based Latent Diffusion architecture, combined with text embeddings from Qwen2.5-VL and the 3D VAE from HunyuanVideo, enabling it to generate 5–10 second videos from textual descriptions. It excels at generating video content related to Russian culture while also supporting English text. Kandinsky 5.0 is suitable for various applications such as video creation, film production, and animation generation.
