AI Video Model Comparison Matrix 2026
A filterable, source-linked comparison of leading generative-video models by input mode, clip length, resolution, native audio and usage economics.
Quick takeaway: there is no universal “best model.” Kling 3.0 is unusually strong when you need longer native-audio clips; Runway Gen-4.5 fits a broader Runway production stack; Hailuo 2.3 offers clear 6s/10s generation economics; Pika 2.5 is optimized for short social experimentation; and Veo 3.1 pushes resolution and reference workflows, but capability depends on the Google endpoint used.

What the specs mean in practice
Longer clips can reduce edit stitching — but increase retry exposure
Kling's 3–15 second range can fit more narrative into one generation. That does not automatically make it cheaper: a failed 15-second generation burns more usage than a failed short clip. For production budgeting, combine the model matrix with a realistic retry factor.
Resolution labels are not interchangeable
Runway's official Gen-4.5 spec currently lists 720p output, while Kling 3.0 offers 720p and 1080p. Hailuo 2.3 reaches 1080p at six seconds but its 10-second option is 768p. Pika 2.5 creator plans offer 480p/720p/1080p generation. Google documents Veo 3.1 endpoints with up to 4K output on selected Cloud paths.
Native audio needs a workflow-level check
Kling VIDEO 3.0 explicitly integrates native audio and multilingual dialogue. For Veo 3.1, Google documentation differs by surface: Google Cloud's Veo guidance describes synchronized audio capabilities, while some Gemini Enterprise model endpoints list sound generation as unsupported. We therefore mark Veo audio as endpoint-dependent rather than forcing a misleading yes/no label.
Model notes
Runway Gen-4.5
Runway documents text-to-video and image-to-video, 2–10 second output, 720p and a rate of 12 credits per generated second. Use it when you value Runway's wider production environment as much as the single model. Read the Runway review →
Kling VIDEO 3.0
Kling's official guide supports flexible 3–15 second generation, 720p/1080p, multi-shot control and native audio. Its published rate ranges from 6 credits/second for 720p without native audio to 12 credits/second for 1080p with native audio. Read the Kling review →
Hailuo 2.3
Hailuo documents text-to-video and image-to-video. Its current 2.3 pricing reference is unusually concrete: 25 credits for 768p/6s, 50 for 768p/10s, and 50 for 1080p/6s. Read the Hailuo review →
Pika 2.5
Pika's creator pricing lists 5s/10s text-to-video and image-to-video across 480p, 720p and 1080p, while the API documents 720p/1080p and pay-as-you-go rates. Pika also has separate effects and longer Pikaframes workflows, so do not assume every Pika generation uses the core 2.5 rate. Read the Pika review →
Google Veo 3.1
Google's current Cloud documentation lists 4, 6 and 8 second clips, text/image input, first/last-frame workflows, reference images, video extension and up to 4K output on selected endpoints. Because the audio capability differs by product surface, check the exact Veo endpoint you plan to use.
FAQ
Which model in this matrix supports the longest single generation?
Kling VIDEO 3.0 and VIDEO 3.0 Omni currently document up to 15 seconds.
Which model is cheapest?
There is no honest answer without a target resolution, duration and retry rate. Provider credits are not equivalent. Use the cost calculator for workflow-level estimates.
Why include official source links in every row?
Generative-video specifications change too quickly for an uncited static table to be trustworthy. Source links make the data auditable and easier to refresh.
