Hailuo 3 First Look: Does MiniMax's New Model Really Rival Seedance?
MiniMax's Hailuo 3 adds omni-reference inputs, multilingual dialogue, and 2K cinematic video. Here's how it stacks up against Seedance so far.
What is Hailuo 3 and why does it matter?
Hailuo 3 is the newest video generation model from MiniMax, arriving roughly nine months after its predecessor, Hailuo 2.3. It’s a multi-modal system that handles standard first-frame/last-frame video generation alongside “omni reference” inputs, meaning you can feed it up to 12 images, plus video and audio, in combination, to guide a generation. Early hands-on testing shows a model that produces coherent dialogue, decent multilingual speech, and stable action sequences at up to 15 seconds per clip in 2K resolution. The model is currently in early access, with wider rollout expected soon.
TL;DR
- Omni reference support lets creators combine up to 12 images with video and audio inputs in a single generation, a meaningful jump in flexibility over prior MiniMax models.
- Dialogue and lip sync held up well in early tests, including full lines of multi-character conversation without the clipping issues common in earlier video models.
- Multilingual prompting works, but only if you write the prompt itself in the target language rather than asking the model in English to switch languages.
- Prompt length caps out at 7,000 characters, which is generous for most use cases but worth knowing if you’re running long, structured (JSON-style) prompts.
- Action scenes favor stability over speed, trading some of the kinetic energy seen in Seedance outputs for fewer morphing artifacts and less teleporting.
- Video extension is supported, letting users continue a scene by feeding a prior clip back in as a reference, though spatial continuity (character position, props) isn’t always perfectly preserved.
- Output quality on character consistency and team-up shots looks close to Seedance 2.0, based on side-by-side style comparisons using the same prompts.
How does Hailuo 3 compare to Seedance?
The comparison matters because Seedance has been a benchmark for cinematic AI video quality in recent months. In early testing, Hailuo 3’s output on prompts previously run through Seedance 2.0, including a sniper-themed action shot and a superhero team-up scene, came back visually close in quality and character fidelity. That’s a notable claim, since matching a leading model on identical prompts is a more honest test than cherry-picked demos.
Where the two diverge is motion style. Seedance tends toward faster, more kinetic action, sharp cuts, quick strikes, and dynamic camera movement. Hailuo 3’s fight and chase sequences move slower and more deliberately. The upside is fewer visual breakdowns: no limbs morphing into other objects, no characters spontaneously appearing in the wrong place, less of the “teleporting” artifact that plagues faster models. This looks like a deliberate design tradeoff, prioritizing spatial and character consistency over raw speed. For creators building narrative content where continuity matters more than chaotic energy, that’s likely the right call.
What can Hailuo 3 actually generate well?
Dialogue-heavy scenes stand out. A diner scene modeled on Twin Peaks produced full, uncut lines for multiple characters, plus small physical acting touches like a finger tap on a table, without the line-clipping that often happens when background characters share a scene with a primary speaker. Mob movie and undercover-agent style scenes rendered coherent tension and appropriate blocking, with only minor continuity slips (a background extra changing identity mid-scene, for instance).
Multilingual output is functional. Testing a samurai character speaking Japanese produced accented but recognizable dialogue, confirming the model can generate non-English speech convincingly. The catch: this only works if the prompt itself is written in the target language. Prompting in English and asking the model to output Japanese doesn’t reliably trigger the behavior.
Image-to-video and surreal image animation also showed clear gains over Hailuo 2.3. A previously static surrealist image, re-run through Hailuo 3, produced far more dynamic and coherent motion than the same input did nine months earlier, a useful before-and-after signal of how fast the underlying model has improved.
What are the current limitations?
Prompt length is capped at 7,000 characters, discovered when a long, structured prompt (the kind built for detailed multi-step choreography) got cut off partway through a fight sequence. That’s a large allowance for most prompts, but worth knowing if you’re building complex, staged scenes with extensive JSON-style instructions.
Extensions, where a prior video clip is fed back in to continue a scene, work but aren’t perfectly consistent. In one diner test, a background character was given a new line via video extension, but her position at the table shifted and a prop (a glass of water) appeared without explanation. The feature works, but spatial and object continuity across an extension isn’t guaranteed yet, so precise prompting matters more than with single-shot generations.

Simple, underspecified prompts (like asking the model to “show me what happens in between” a first and last frame with no other detail) tend to produce technically correct but uninspired results. This is arguably more a prompting issue than a model limitation, but it’s a reminder that Hailuo 3, like most current video models, rewards specificity.
Is Hailuo 3 worth trying right now?
For anyone already building with Seedance or similar cinematic video models, Hailuo 3 is worth testing directly against your existing prompts. The character consistency across omni references, the multilingual dialogue support, and the 2K output at up to 15 seconds per generation put it in serious contention. The tradeoff of slower action for more stability will suit narrative and dialogue-driven content better than fast-cut action content, so the right choice depends on the project.
Since the model is still in early access and MiniMax is actively iterating, current impressions should be treated as a snapshot rather than a final verdict. Pricing details were still emerging at time of testing, but early quality comparisons suggest it’s positioned to compete directly on cost and capability with Seedance rather than sit in a cheaper, lesser tier.
Frequently Asked Questions
What is Hailuo 3 used for?
It’s a text-to-video, image-to-video, and omni-reference video generation model, used for creating short cinematic clips, dialogue scenes, character-consistent action sequences, and video extensions from combined image, video, and audio inputs.
How is Hailuo 3 different from Hailuo 2.3?
Hailuo 3 adds omni-reference support (up to 12 images plus video and audio), improved dialogue handling with less line-clipping, better multilingual speech generation, and noticeably improved motion coherence compared to the 2.3 model released nine months earlier.
Does Hailuo 3 support multiple languages?
Yes, but the prompt itself needs to be written in the target language. Asking in English for the model to generate dialogue in another language doesn’t reliably work; writing the prompt directly in that language does.
How long can a Hailuo 3 video generation be?
Generations run up to 15 seconds at 2K resolution per clip, with support for extensions that let users continue a scene using a prior video as a reference input.
Is Hailuo 3 better than Seedance?
Early side-by-side testing on identical prompts shows comparable output quality, particularly on character consistency. Hailuo 3 favors stability and fewer visual artifacts over the faster, more kinetic motion typical of Seedance, making the “better” answer dependent on the use case.
