Is HelloGen really free?
Making images is: unlimited on a free account, never watermarked, commercial license included. Video on the flagship models runs on credits — from a plan or a one-off pack from $4.90 — because every clip is paid compute at a vendor. Pro and Max also include unlimited video on MiniMax H3 Unlimited, which costs no credits at all. The plan card shows the exact price before you generate, and failed generations are never charged.
Do I need to know how to write prompts?
No. Describe what you need in plain words; the assistant picks a skill, asks at most one question and writes the prompt for the model. You can always open and edit the prompt yourself.
How much does the Omni Agent cost?
It is included with Pro and Max — there is nothing to estimate before you send a message, and the plan card still shows the price of the images or clips it proposes before anything is generated. Free and Basic accounts can generate on their own in the Studio; the agent is what Pro adds.
Which AI models does it use?
Nano Banana (Lite / 2 / Pro), Seedream 4.5 / 5 and GPT Image 2 for images; Veo 3.1, Kling 3.0, Seedance 2–2.5, MiniMax H3 and HappyHorse for video, plus MiniMax H3 Unlimited for Pro and Max. The assistant chooses per job — you can always ask for a cheaper or a better one.
Can I use the results commercially?
Yes. Everything you generate comes with a commercial license and no watermark, on every plan.
What if a generation fails?
You are never charged for failed generations, and the plan card shows the exact price before you press Generate.
What does “unlimited video” mean exactly?
On Pro and Max, clips on MiniMax H3 Unlimited cost no credits and there is no daily cap — 480p, up to 15 seconds, with generated sound. Every day you also get guaranteed priority clips (at least 2 a day on Pro, 5 on Max), and clips beyond those render at standard speed. Everything else about it is the same as a paid model: failed renders cost nothing, and the clip is yours commercially.
