Speaking of AI video models that have been highly discussed recently, MiniMax H3 is definitely one of them. It focuses on fast generation, native audio, and fairly impressive motion quality, so many people are sure to want to try it out. The good news is that “fal.ai,” a platform focused on generative AI cloud models and GPU inference, suddenly became very generous and directly opened MiniMax H3 Max for everyone to try for free—you can even generate videos without registering. However, it’s worth noting that fal has not announced how long this free trial of MiniMax H3 Max will last, so if you’re interested, be sure to take advantage of it, as it could end at any time.

fal lets you use MiniMax H3 Max for free to generate videos — here are the precautions and instructions.
Some might wonder what MiniMax H3 Max is. Is it a newly released model? No, it’s a version by fal Research based on MiniMax’s open-weight H3, further optimized through post-training and inference. In addition to retaining H3’s original high-speed generation and native audio capabilities, it has also been specifically tuned for prompt adherence, visual aesthetics, and generation efficiency, making it especially suitable for creating fast-paced, high-motion AI short videos.
The following are the highlights of this free trial from fal:
- You can directly generate MiniMax H3 Max videos without registering for a fal account.
- Although the official event page states that each account can generate for free 5 times, in reality, you can keep generating without even registering (480p).
- If you’re not registered, every generation is just a 5-second short video.
- After logging in, you can generate videos up to 15 seconds long at 768P resolution, but you’ll need to enter payment information.
- Supports text-to-video and image-to-video generation.
- Support for native synchronized audio generation
- fal has not currently announced an end date for the free event.
Go to the MiniMax H3 Max event page
After clicking the link above to enter the MiniMax H3 Max event page, click Generate free on the screen:
Then you can enter your video prompt. In the bottom-left corner, you can add reference images. The video supports aspect ratios 16:9, 9:16, and 1:1. Once you’re ready, click Generate to start generating:

Wait about 3 seconds and the results will appear, it’s very fast:

After the video is generated, you can play it online first. If satisfied, click Download below to download it; if not, just regenerate. Free generation without registration can only produce 5-second 480p videos. If you want to extend to 15 seconds 768P, you need to register an account + add payment information:

Login methods support three options: GitHub, Google, and SSO.

Go to the backend Sandbox, where you can generate 15-second 768P videos, but the free quota clearly states that you must Add Payment:

Finally, one more reminder: fal hasn’t announced an end date for the MiniMax H3 Max free trial, so this isn’t guaranteed to be a long-term free plan. The free quota, resolution, video length, or even the entire campaign could be adjusted or discontinued at any time.
