How to Generate AI Images: A Practical Guide (2026)

AI image generation turns a written description — a prompt — into an original image in seconds. NamiFusion's AI Generator brings today's top text-to-image and image-to-image models into a single interface, with prompt presets, reference image input, reusable seeds, and batch output. You get free credits at signup, and paid generation runs on credits at $1 = 100, with each model's approximate per-image price shown before you run it.

TL;DR

One interface, many top models — pick the right model per job instead of committing to a single provider.

Supports both text-to-image and image-to-image with reference input.

Seeds and the 'use as reference' button let you reproduce and iterate on results instead of gambling on every run.

Batch generation plus an on-page history make comparing variations painless.

Unfiltered engine: your prompts are not blocked by a content filter. Free credits at signup, then $1 = 100 credits.

What can you make with an AI image generator?

The obvious outputs — social posts, thumbnails, concept art — are just the start. I use the AI Generator for product mockups in settings that would otherwise require a studio rental, character sheets for stories and games, and mood boards that would normally eat an afternoon of stock-photo hunting. Because batch generation and history live on the same page, exploring ten directions costs minutes, not hours.

Image-to-image widens this further: sketch a rough layout, feed it in as a reference, and let the model handle the rendering. And since results chain into NamiFusion's other tools — a generated portrait can become a face swap source or the first frame of a video — the generator often sits at the start of a much longer pipeline.

How do you generate an AI image step by step?

1. Open the AI Generator on NamiFusion and sign in — free credits are added automatically.

2. Pick a model. Each card shows what it is good at and an approximate dollar price per image.

3. Write your prompt, or start from a prompt preset and edit it.

4. Optionally add a reference image to guide composition or style (image-to-image).

5. Set the batch count to generate several variations in one run.

6. Hit generate — results land in the history alongside all your previous runs.

7. Found a keeper? Reuse its seed for controlled variations, or click 'use as reference' to feed it into the next generation.

How do you write a good image prompt?

A reliable prompt names four things: the subject, the style, the lighting, and the composition. 'A woman in a city' is a coin flip; 'portrait of a silver-haired woman on a neon-lit street at night, cinematic lighting, shallow depth of field' is a brief the model can actually execute.

Iterate in small steps. Change one element at a time — the lighting, then the lens, then the mood — and keep the seed fixed so you can see exactly what each change did. NamiFusion's prompt presets are useful starting points when you are staring at a blank box.

How much does AI image generation cost?

It starts free: signup credits cover your first rounds of generation. After that you buy credits at $1 = 100 and spend them as you go — there is no monthly fee.

The per-image credit price varies by model, and every model card shows an approximate '$X per image' figure. Batching several variations multiplies the cost accordingly, so a sensible habit is to draft with a cheaper model while exploring, then switch to a flagship model for the final render.

Want to poke at a specific model before spending credits on it? Its Playground page in the API marketplace lets you try it for free.

How do you keep characters and styles consistent?

Seeds are your first tool: the same seed with the same prompt reproduces the result, so fixing the seed and nudging the prompt gives you variations of the same image rather than a completely new roll.

Reference images are the second: feed a finished result back in with 'use as reference' and it carries the character's look, outfit, or overall style into the next scene. This chaining workflow is the most practical way to keep one character consistent across many images.

Finally, prompt presets can lock in a style vocabulary. When producing a series, keep the style half of a winning prompt as your template and start every image from the same words.

Can you generate images through the API?

Yes. The models behind the AI Generator are also exposed in NamiFusion's API marketplace — 98+ models behind one REST API, priced in credits per call. Create a key at /api-keys, submit a job with the request below, then poll the task endpoint for the result.

Before integrating, validate your prompt for free on the model's Playground page, then hard-code what works.

curl -X POST "https://www.namifusion.com/api/v1/marketplace/run/<model_id>" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "input": {
      "prompt": "portrait of a silver-haired woman on a neon-lit street, cinematic lighting",
      "seed": 42
    }
  }'
