How to generate AI images in bulk
Updated October 18, 2026 · By Personifex
This is how the operator who builds Personifex runs bulk image generation. A batch is 50 to 100 images, every one from a different prompt, on a low-cost model. Failures retry on their own, and the review at the end takes minutes, not an evening.
On their own WaveSpeed key, a batch like that costs them between two and five dollars.
Many prompts, not one
Running one prompt a hundred times gives you a hundred near-copies. A different prompt per image gives you a hundred different posts to choose from. There are two quick ways to get that many:
- The Prompt maker writes a batch of prompts from an idea, from images, from earlier prompts or from your library, on your own OpenRouter key. Read the drafts and add the ones you like to the queue.
- Import a text file: Import in Generate, or Import text file in Prompts. Separate the prompts with a line of three dashes, so one prompt can run over several lines.
Morning coffee on a sunny balcony, oversized cream knit, phone photo --- Walking a farmers market with a tote bag, golden hour, candid --- Reading on a window seat on a rainy day, soft lamp light
The file can be .txt or .md, up to 5 MB. Generate skips any prompt that is already in the list.
A low-cost model for volume
For volume this operator reaches for the cheaper models: Seedream most of all, plus Nano-Banana and Meta's Muse. At WaveSpeed's list price, before any sale:
| Model | From, per image | 100 images from |
|---|---|---|
| Meta Muse Image | $0.011 | $1.10 |
| ByteDance Seedream v5.0 Flash | $0.027 | $2.70 |
| Google Nano-Banana | $0.038 | $3.80 |
Each model's page has its full price grid, and the cheapest model for each job ranks them for common jobs.
See the price, then Start
Before anything runs, the Start button shows what the whole batch will cost, and the line above it shows the price of each image on the model and resolution you picked.
A batch runs up to 20, 50 or 300 images at once depending on the plan. Start takes as many waiting prompts as fit and leaves the rest queued for the next batch. A new WaveSpeed account runs only two at a time until its first top-up, of any size: setting up a WaveSpeed key covers that step.
Let failures retry
Some calls fail; at volume, that is normal. The Passes setting retries a failed image on its own, up to 4 tries in all, so a batch needs no babysitting.
An image that fails every pass is marked Failed. In this operator's experience that points at the prompt, not the model: rewrite it and queue it again.
Review in minutes
Review shows one image at a time and rates it with one key, so a batch of 50 to 100 takes this operator two to three minutes:
| Key | Rating |
|---|---|
| 1 | Trash |
| 2 | Good |
| 3 | Great |
| 4 | Needs edit |
| Z | Undo the last rating |
The arrow keys move back and forth without rating. Keeping a persona consistent covers what makes an image Trash or Needs edit.
What this cannot promise
The two to five dollars is one operator's spend on their own models and resolutions; yours moves with both, and the price before Start is the number to trust. This guide gives no keeper rate either: how much of a batch you keep depends on the prompts, the model and your taste.
