Quick comparison: which access path to choose?

Google AI Studio
Best for fast experiments, prompt testing, and small‑scale trials.

Gemini API
Best for automation and production pipelines.

Vertex AI
Best for enterprise governance, billing, and security controls.

Using Google AI Studio (step‑by‑step)

Sign in to Google AI Studio.
Create an image‑capable workspace.
Select Gemini 2.5 Flash Image / Nano Banana.
Add a prompt and optional reference image.
Generate and iterate.

If results drift, shorten the prompt and add constraints like “keep face” or “preserve pose.”

Using the Gemini API

The API is token‑based. As of late 2025, a 1024×1024 output is around $0.039 per image. Pricing and quotas can change, so confirm in official docs.

Practical tips

Start with lower resolution for prompt testing
Keep prompts short and explicit
Use reference images for consistency

Using Vertex AI

Vertex AI is the right choice when you need:

Centralized billing
Access control and audit trails
Enterprise‑grade logging

It’s commonly used by teams that run high‑volume generation or need compliance visibility.

When to use img2img.online instead

Choose img2img.online if you want:

A fast, UI‑first workflow
Built‑in credit tracking
Easy sharing and iteration
Subscription exports without visible watermarks

You can prototype in AI Studio or API, then move to img2img.online for speed and team collaboration.

Common access issues

I can’t find the model.
It may not be available in your region or account. Check your AI Studio model list or API docs.

Results are inconsistent.
Use stronger constraints, reduce prompt length, and add a clear reference image.

Can I use it for video?
No. Nano Banana is image‑only.

Summary

Gemini AI Studio is best for quick tests, the Gemini API is best for automation, and Vertex AI is best for enterprise. Use img2img.online when you want speed, UI simplicity, and credit‑based tracking.
