As of mid-2026, there is no single best AI video model — the field has matured into specialists. On Bno AI the working shortlist looks like this: Veo 3.1 Fast or Sora 2 when the clip has to look its best, Kling v3 when you want the model to generate audio along with the picture, Hailuo 2.3 for motion-heavy shots that follow camera directions, and Grok Imagine 1.5 when you just want to try video for a handful of credits. Most production work routes between two or three models depending on the scene, which is exactly the workflow Bno AI is built around: all seven models below live behind one video generator.
The seven models at a glance
Veo 3.1 Fast (Google DeepMind). The speed-optimized variant of Google's Veo line, known for cinematic framing and lighting straight out of the prompt. Clips are a fixed 8 seconds, at 720p or 1080p for the same price — a flat 128 credits per clip, so the cost never surprises you.
Sora 2 (OpenAI). OpenAI's video model, with a reputation for physical plausibility and narrative coherence — objects interact believably and a described sequence of events tends to play out in order. Generates 720p clips at 4, 8, or 12 seconds.
Kling v3 (Kuaishou). The one model in this lineup with an audio generation option: toggle it on and the clip comes back with sound, at a higher credit cost. Outputs 720p or 1080p at 5 or 10 seconds.
Hailuo 2.3 (MiniMax). Strong, fluid motion is the calling card, and it responds well to explicit camera directives in the prompt — push-ins, pans, orbits. Generates 768p or 1080p clips at 6 or 10 seconds; note that 1080p is 6s only, and 10s requires 768p.
Seedance 2.0 (ByteDance). Supports a reference image input to steer a generation and scales from 480p drafts up to 1080p output. The widest cost spread in the lineup: cheap at 480p, premium at 1080p.
Wan 2.7 (Alibaba). Alibaba's video model and a solid value pick: 720p or 1080p at 5 or 10 seconds, priced below the premium tier.
Grok Imagine 1.5 (xAI). The budget tier and the cheapest way to try AI video, period: a 6-second 480p clip costs 9 credits — within the free plan's 10 daily credits. It is also the only model here that reaches 15 seconds.

Picking by need
- Cheapest way in: Grok Imagine 1.5. At 9 credits for a 6-second 480p clip, even the free plan's daily credits cover one — generate first, decide whether video is for you after.
- Best quality ceiling: Veo 3.1 Fast or Sora 2. Run the same prompt on both; the better fit for your style is usually obvious within one generation.
- Audio in the clip: Kling v3 — switch on audio generation and budget roughly half again the silent price.
- Longest clips: Grok Imagine 1.5 at 15 seconds, then Sora 2 at 12. Everything else tops out at 10.
- Steering with a reference: Seedance 2.0 supports a reference image input, useful when text alone isn't enough to pin down the look.
Using these models on Bno AI
All seven models live behind a single interface — open the generator or the video generator, choose a model, and switch freely between generations. There is no separate account, queue, or pricing scheme per provider.
The practical details:
- Video is gated by credits, not by subscription. Any account with enough balance can generate — the free plan's 10 daily credits cover one Grok Imagine clip. For volume, Pro is $20/month with 2,000 credits ($120/year, effectively $10/month); Ultimate is $40/month with 5,000 credits.
- Credit cost varies by model, duration, and resolution — from 9 credits (Grok, 6s at 480p) to 704 (Seedance, 10s at 1080p) — so a balance stretches much further on lighter models.
- Both text-to-video and image-to-video are supported across the lineup.
- A practical workflow: iterate on Grok or Hailuo, then re-render the keeper on Veo 3.1 Fast or Sora 2.
FAQ
Can I generate video on the free tier? Yes. Video is charged in credits, not locked to a plan — a 6-second 480p Grok Imagine clip costs 9 credits, which fits within the free plan's 10 daily credits. One clip per day, no subscription needed.
