Veo 3.1 is an AI video generation model by Google. It excels at scene composition and lighting and is priced at $0.10-$0.40/s. Quality rating: Very High. Generation speed: Medium.

The main limitation of Veo 3.1 is expensive at full quality. Despite this, it remains one of the most popular choices for AI video generation in 2026.

Runway Gen-3 is an AI video generation model by Runway. It excels at creative experimentation and is priced at $0.05-$0.10/s. Quality rating: Good. Generation speed: Medium.

The main limitation of Runway Gen-3 is quality now behind newer models. It has built a strong user base among creators who prioritize its specific strengths.

For most social media content (TikTok, Reels, Shorts), both models produce adequate quality. The differences become more apparent in cinematic content, ads, and brand videos where visual fidelity matters more. Through FluxNote's AI Studio, you can try both models on the same prompt and compare outputs side by side.

Through FluxNote's AI Studio, both models are accessible on paid plans starting at $9.99/month. This includes not just the AI generation but also voiceover, animated captions, and background music — features that would cost $30-60/month extra if using these models directly through their APIs.
