What AI models TubeGen uses, and what each one costs
Quick answer
TubeGen uses Grok Imagine, GPT Image and Nano Banana 2 for image generation, and Seedance, Pixverse, Grok Imagine and Gemini Omni for animation. Scripts are written by TubeWriter, TubeGen's own writer, in four modes. Voiceover, soundtrack and avatars each run on a dedicated model. Every model is included in every plan and billed per generation in credits, from 22 credits for a Grok Imagine image to 120 for Nano Banana 2 at 1080p. Batch delivery cuts GPT Image and Nano Banana 2 costs by 40-50%.
Each stage of the pipeline uses the model suited to it. The models create the pieces; TubeGen writes the prompts, connects the stages, and assembles the video. For the wider category, see AI video generation models.

Why more than one
Why TubeGen uses more than one image model
Image models have different strengths, so TubeGen offers three and lets you pick per project or per section. Animation works the same way. One model for everything would mean paying the top rate on scenes that do not need it.
The models vs the product
Is TubeGen just a wrapper around other AI models?
No. The models are components, and the product is the assembly.
What the models do
- Write text from a prompt
- Generate one image or one short clip from a prompt
- Read a script aloud in a voice
What TubeGen does
- Writes a specific prompt for every scene, in your art style and with your characters
- Connects research, script, voice, visuals, music and edit in one place
- Times visuals and music to the narration and assembles the cut
- Adds its own tools: Niche Finder, AI Title Generator, Thumbnail Studio, Video Editor
