9 Best MiniMax H3 Fine-Tuned Models in 2026
MiniMax H3 is becoming the starting point for a wave of independently branded video, image and interactive-media models. The teams below did not just wrap an API or train a quick community LoRA; they post-trained, distilled or fully fine-tuned H3 into their own products. If you would rather run the base model directly, you can use the MiniMax H3 API on Pixazo, but this guide is about the nine most substantial H3-derived models and how they actually differ.
We compare them on what they can do (text-to-video, image-to-video, reference-to-video), how long a clip they make, which references they accept, and the real cost of a 15-second render. Prices are published, configuration-specific rates that can change, so treat them as a guide and confirm the exact endpoint before you build.

15-second API cost compared
USD at published, configuration-specific rates; provider pricing and promotions may change. A 1080p or 4K offering may be an upscaled output rather than native generation. A dash means a standardized comparable hosted price was not established.
| Standard output | 480p / 15s | 768p / 15s | 1080p / 15s |
|---|---|---|---|
| Pika H3 Flex | $0.15 | $0.30 | $0.525 |
| HeyGen Video 1 | $0.15 | $0.27 | $0.60 |
| fal H3 Max | $0.75 | $1.20 | $2.40 |
| Pruna Pro – Cost | $0.15 | $0.375 | $0.675 |
| Pruna Pro – Speed | $0.30 | $0.525 | $0.825 |
| Pruna Pro – Quality | $0.60 | $1.125 | $1.425 |
| Pruna Pro Avatar | $0.30 | $0.60 | $0.90 |
Reference-to-video: a more realistic bill
Illustrative scenario: a 15-second 768p output plus one 10-second video reference. Reference-input pricing is often separate from generated output, and token allowances or provider rounding can change invoices. These are estimates, not guaranteed quotes.
| Provider / mode | Output | Reference input | Estimated total |
|---|---|---|---|
| Pruna Pro Reference / Cost | $0.375 | $0.60 | $0.975 |
| HeyGen Video 1 | $0.75 | $0.50 | $1.25 |
| Pika H3 Flex | $0.90 | $0.60 | $1.50 |
| fal H3 Max | $1.20 | ~$1.41 | ~$2.61 |
1. Pika H3 Flex
Cinematic storytelling and multimodal creative control
Pika's H3-derived model combines post-training, distillation and preference-based optimization. Its published research describes reducing denoising from roughly 50 steps to six. The model supports text-to-video, first and last-frame image animation and multimodal reference-to-video, with synchronized sound.
Capabilities and limits: Up to 15 seconds; up to 4K finishing (upscaled). Reference workflows allow combinations of images, videos and audio, subject to aggregate limits.
Pricing: 480p $0.01/s; 768p $0.02/s; 1080p $0.035/s on the compared rate card; reference-video inputs may add charges.
2. HeyGen Video 1
Marketing and business-ready video generation
A branded H3 post-trained offering supporting text, image and reference-conditioned video. Reference handling is relevant for keeping products and people recognizable across clips. Separate long-duration modes may be priced differently.
Capabilities and limits: Common short-clip workflows are 5 to 15 seconds. Documentation includes longer-duration rate categories, so confirm the intended endpoint and maximum before describing this as unlimited. Up to 2K advertised.
Pricing: 480p $0.01/s; 768p $0.018/s; 1080p $0.04/s for standard generation in the compared table. Reference mode differs.
3. fal H3 Max
High-quality API video and accelerated inference
Fal has combined H3 post-training with serving optimizations. It offers text-to-video, image-to-video and multimodal reference-to-video. Vendor demonstrations highlight strong prompt adherence and faster serving, but comparative quality claims should be backed by a matched benchmark.
Capabilities and limits: Standard generation workflows support up to 15 seconds and 1080p. Audio generation is supported. Reference inputs may incur token charges after an included allowance.
Pricing: 480p $0.05/s; 768p $0.08/s; 1080p $0.16/s in the compared standard rate card.
4. Pruna P-Video-2-Pro
Low-cost and scalable video workflows
Pruna exposes Cost, Speed and Quality configurations rather than one fixed trade-off. Standard generation supports text-to-video and first and last-frame conditioning. Rich multimodal references live in the separately priced P-Video-2-Pro-Reference offering.
Capabilities and limits: Up to 15 seconds. Native 480p and 768p generation; 1080p, 2K and 4K outputs are delivered with upscaling. Generated sound is supported.
Pricing: Cost mode: 480p $0.01/s; 768p $0.025/s; 1080p $0.045/s. Reference-video billing is additional.
5. Viggle Animate
Character replacement while preserving source performance
Viggle describes Animate as a 33.1B-parameter full fine-tune of an H3 reference-to-video transformer. It uses a driving video and an edited frame, attempting to preserve timing, camera motion and body movement as the character appearance changes.
Capabilities and limits: Not general-purpose text-to-video. Maximum runtime and available resolution are workflow-dependent. Public weights are available; no directly comparable standard commercial per-second rate is established.
Pricing: Self-hosted economics depend on inference hardware and throughput.

6. Pruna P-H3-Image
Still-image generation and image editing
An unusual H3-derived product dedicated to text-to-image creation and reference-driven image editing rather than moving footage. Pruna publishes open weights and reports accelerated, reduced-step inference compared with its baseline.
Capabilities and limits: Outputs images, not 15-second video. Supports high-resolution still output and multiple image references. Check the exact checkpoint for supported pixel-size limits.
Pricing: No comparable H3-specific per-image list price verified; self-host GPU costs vary.
7. XGEN-JING
Action-conditioned interactive visual worlds
XGEN-JING applies H3-derived capabilities to evolving audiovisual environments. Inputs can include character and environment references, observation history and user actions, rather than a simple standalone text prompt.
Capabilities and limits: Interactive generation rather than fixed-length commercial clips. Runtime, output size and infrastructure depend on the research implementation.
Pricing: No standard public per-second API quote established.

9. Pruna P-Video-2-Pro-Avatar
Talking-character and lip-sync videos
A specialist H3-derived model taking a portrait and speech or a script to generate a talking-person video. It is different from cinematic text-to-video because its objective is synchronized speech and natural facial animation.
Capabilities and limits: Supports much longer spoken outputs, up to three minutes on the published product information. Higher-resolution output may use upscaling.
Pricing: 480p $0.02/s; 768p $0.04/s; 1080p $0.06/s. 15-second examples: $0.30, $0.60 and $0.90.

The bottom line
There is no single best MiniMax H3 model, because these nine solve different problems. For cinematic clips with rich references, Pika H3 Flex is the most complete toolset; for the lowest entry price, Pika, HeyGen and Pruna Cost mode sit near $0.01 per second; for reference-heavy work, weigh the input charges, not just the output. Viggle owns character replacement, Pruna Pro Avatar owns talking portraits, FastH3 Omni suits self-hosting, and P-H3-Image is the odd one out that makes stills. Match the model to the job, confirm the live price and maximum duration on the exact endpoint, and if you just want the base model, run MiniMax H3 directly on Pixazo.

Frequently asked questions
What is MiniMax H3?
MiniMax H3 is a video-generation model family that several independent teams have post-trained, distilled or fully fine-tuned into their own branded products. This guide compares nine of those H3-derived models on capabilities, duration, references and 15-second API pricing. You can also run MiniMax H3 itself through the Pixazo API.
Are all nine full-weight fine-tunes?
No. They are substantial branded H3-derived products, including full fine-tunes, post-trained systems and distilled full checkpoints. Viggle explicitly identifies a full fine-tune; other developers disclose varying levels of detail.
Can all nine make a 15-second clip?
No. Six are video-oriented, but Viggle is task-specific, P-H3-Image outputs still images, and research or interactive runtimes have different duration rules.
Which MiniMax H3 model is cheapest?
For standard short 480p generation, Pika, HeyGen and Pruna Cost mode share a cited entry rate of about $0.01 per second. For reference-heavy jobs, compare the reference-input charges too, since they are often billed separately.
Can these models be hosted commercially?
For open checkpoints, confirm the GPU requirements and every applicable licence term, including upstream MiniMax territorial and commercial constraints, before deployment.
