Video Models¶

License notes: The commercial-use status covers model weights, derivative checkpoints, fine-tunes, and hosted model use. Generated-output rights can differ; read the linked license text before commercial deployment.

¹ OpenRAIL-style licenses generally permit commercial use with usage restrictions that remain attached to the model and derivatives.

² Stability AI Community License is available for qualifying users below the revenue threshold; larger commercial use needs Stability enterprise terms.

³ Flux.1 varies by flavour: Schnell and LibreFlux are Apache-2.0, while Dev, Krea, and Kontext use BFL non-commercial terms; review FluxBooru upstream metadata before commercial use.

⁴ Flux.2 varies by flavour: Klein 4B is Apache-2.0, while Dev and Klein 9B use BFL non-commercial terms.

⁵ Public non-commercial model terms do not permit commercial use of weights, derivative checkpoints, or hosted model services without a separate license.

⁶ Krea 2 Community License permits commercial use under its revenue cap (under $1M annual revenue) and safety/filtering requirements; otherwise an enterprise license is required.

⁷ Abandonware means the original vendor has effectively left the model behind and there is no reliable permission path; end users must decide whether that risk is acceptable.

⁸ AuraFlow supports Apache-2.0 upstream flavours and a Pony flavour with a separate custom license; check the selected flavour.

⁹ NVIDIA Open Model License permits commercial use but includes agreement, acceptable-use, and export-control terms.

¹⁰ LTX Video 0.9.5 uses OpenRAIL-M; LTX Video 2 uses LTX community terms with a revenue threshold for commercial use.

¹¹ Tencent Hunyuan Community License includes territorial exclusions and a commercial threshold for very large services.

¹² MiniMax H3 Community License excludes the United States, European Union, United Kingdom, and South Korea from the standard applicable territory; those territories require separate authorization.

Choosing a Model¶

For beginners:

• Start with Flux.1 for high-quality image generation
• Use LoRA training to reduce memory requirements

For production:

• SD3 or SDXL for broad compatibility
• Flux.2 for maximum quality (requires more VRAM)

For video:

• Wan Video for best quality/resource balance
• Hunyuan Video for I2V with super-resolution

For specific use cases:

• Flux Kontext for image editing/conditioning
• ACE-Step for text-to-music LoRA training (v1 and v1.5)
• HeartMuLa for autoregressive text-to-audio
