Cat-MaineCoon
Real-time audio-visual generation for social video, powered by a 22B multimodal autoregressive model.
What is Cat-MaineCoon?
Cat-MaineCoon is an advanced real-time audio-visual generative model designed for the next generation of social video and interactive media. Built around a 22-billion-parameter multimodal autoregressive architecture, it generates synchronized video and audio from prompts and can stream output with sub-second interaction latency. On a single H100 GPU it reaches up to 47.5 frames per second, and the cost per generated second is below $0.001, making live, AI-generated social content economically practical. Unlike conventional video generators that operate in offline batch mode, MaineCoon adopts a forcing-free streaming training paradigm, including self-resampling, cross-modal representation alignment, domain-aware preference optimization, and reinforced on-policy distillation (ROPD). It also includes an agentic streaming inference framework with cache management, chunk commitment, long-context rollout, and prompt planning to keep long-running generations coherent and drift-free over thousand-second horizons. The model is presented with SocialVideo Bench, a new benchmark for evaluating audio-visual generation on social-video-style content. MaineCoon reports state-of-the-art quality and speed compared with seven representative open audio-visual models. It is currently available through limited early access, aimed at developers, researchers, and platform teams exploring real-time multimodal content creation.

Pros & Cons of Cat-MaineCoon
Pros
- Fastest-in-class generation: up to 47.5 FPS on a single H100 GPU
- Ultra-low cost: under $0.001 per second of generated audio-visual content
- Synchronized audio and video from a single multimodal model
- SOTA on the new SocialVideo Bench, outperforming 7 representative open models
- Supports long-running, streaming generation with drift-mitigating agentic inference
Cons
- Limited early access only; not yet a fully public product.
- Requires a high-end H100-class GPU to achieve full real-time performance.
- Benchmarked primarily for social-video-style content, so general-purpose video and audio creation is not demonstrated.
- No details on open weights, API pricing, or commercial terms were provided.
Frequently Asked Questions
What is MaineCoon?
