How to Generate Consistent AI Characters (March 2026)

If you've ever tried to create an AI avatar or character for your brand, you know the problem.

You generate something you love, then try to recreate it in a different pose or setting, and it looks like a completely different person.

Here's how I'm solving that right now:

Step 1: Use Nano Banana Pro

As of early March 2026, Nano Banana Pro (Google's image model inside Gemini) is the best tool I've found for generating consistent characters (I like it more than Nano Banana 2). It's built on Gemini 3 Pro, and the character consistency is noticeably better than anything else I've tested. I'm still experimenting with other models, but this is what's working for me right now.

You can access it for free through the Gemini app. Google AI Pro/Plus/Ultra subscribers get higher usage limits.

"But what about the watermark?"

If you use the free version through Gemini, Google puts a visible watermark on the bottom right of every image. To get around that, you can use platforms like WaveSpeed AI or Higgsfield that plug into the Nano Banana Pro API directly. This lets you generate with the same model, without the watermark. You can also hit the API yourself if you're comfortable with that.

Step 2: Generate Your AI Avatar

Use Nano Banana Pro to create your base character. Be specific in your prompt. Describe facial features, hair, clothing, and style. The more detail you give it, the more consistent your results will be across future generations.

This is your "master image."

Step 3: Upscale That Avatar

AI-generated images often come out at a lower resolution than what you'd want for professional use. I run mine through Topaz Gigapixel to clean it up and bring it to a higher resolution. This makes a big difference when you're posting across LinkedIn, newsletters, carousels, etc.

Step 4: Use It as Your Reference Image

This is the key step most people skip. Take that upscaled avatar and use it as your reference image every time you generate new content. Upload it into Nano Banana Pro alongside your new prompt, and it will keep your character looking the same across different scenes, poses, and settings.

That's it. Generate once, upscale once, reuse forever.

I'm still testing other models and workflows, so if this process changes, I'll update this post. But as of right now, this is the simplest path I've found to consistent AI characters without needing Midjourney, ComfyUI, or a design background.
