Hailuo 2.3 vs Gen-4.5
Hailuo 2.3 is the cheaper of the two at 52 credits per clip against Gen-4.5's 78 — a 26-credit gap on every generation. Hailuo 2.3 returns a clip in ~65s / 5s clip against Gen-4.5's ~90s / 5s clip, which compounds quickly if you are iterating rather than finishing. Gen-4.5 produces the longer single clip at up to 20 seconds versus 10. Neither generates audio — plan on a separate sound pass for both. If you can only choose one, pick on clip length and audio, then let the other handle the volume work.

Pick Hailuo 2.3 when…
- You are generating in volume and the 26-credit difference per clip adds up fast
- You are still exploring and need a tight generate-judge-regenerate loop (~65s / 5s clip versus ~90s / 5s clip)
- The brief leans on realistic human motion
Trade-off: You are capped at 10s per clip and will need extension or a cut for anything longer.
Pick Gen-4.5 when…
- The clip is a final deliverable and 26 extra credits per render is not the constraint
- You have settled on the shot and are rendering the version that ships
- The shot cannot be cut — you need up to 20 seconds in one generation rather than 10
- The brief leans on text & image to video
Trade-off: You pay 26 more credits on every generation; You wait 25s longer per clip.
Vendor angle
These come from different vendors — MiniMax and RunwayML — which is where the interesting differences live. Vendors train on different data and optimise for different failure modes, so the same prompt can produce recognisably different motion, grain and lighting. On FlowAIVideo both sit behind one account and one balance, so you never have to pick a vendor before you have seen the output.
What it costs to decide
Running one clip on each costs 130 credits in total (52 + 78). A new account starts with 40 free credits, which covers Hailuo 2.3 plus part of the other — enough to run a real comparison rather than reading about one. Paid plans start at 600 credits per month, and there is no per-model subscription: one balance, 22 models.
Test them on this prompt
A cyclist pedalling along a coastal road at golden hour, low tracking shot from behind the front wheel, shallow depth of field, 5 seconds
Fix the duration and aspect ratio, run both, and judge prompt adherence before aesthetics. A clip that looks good but shows the wrong thing is a failure.
