GPT Image 2 API

Introduction

GPT Image 2 Text to image is OpenAI's gpt-image-2 model, released in April 2026, generating images from a written prompt. It follows long, specific briefs, sets quoted headlines and labels into the picture as legible type, and renders at three quality tiers and three size tiers in fifteen aspect ratios.

Key features

Text you can read

Headlines, cover lines, signs and labels written in quotes come back as real type. In our poster and magazine-cover tests every quoted line rendered with the right spelling at medium quality.

Request parameters

Pricing

Prices are in credits, the same credits you use on the website (1 credit = $0.01). The hold is taken when the task is accepted and settled to the actual charge when it finishes; failed tasks are refunded.

Each task is rounded up to whole credits, so one run at the lowest tier costs 1 credit per image ($0.01).

For an exact number before you run, send the same body to POST /jobs/quote.

Use cases

Posters, covers and ads

Layouts where the words matter as much as the picture: film posters, magazine covers, sale banners and packaging mock-ups, produced in one call instead of a picture plus a separate typesetting pass.

Variations for review

Up to ten images from one brief in a single request, so a team can pick a direction before anyone pays for the high tier.

Prompt guide & pro tips

Quote and place every line

Write each piece of text in double quotes and say where it goes: across the top, bottom left, on the sign. Unquoted words are read as description, not as type to set.

Describe the photograph, not keywords

Full sentences about subject, wardrobe, setting, light and lens work better than tag lists. Name the medium as well: film still, studio product shot, magazine cover.

Draft at low, finish higher

Keep the prompt unchanged and move up a tier for the final.

Match the size tier to the use

Use 1k for screens and social posts, 2k for large displays and 4k only for print or heavy cropping.

API quick start

Call the GPT Image 2 API in three steps

1. Create an API key. Sign in to PopNow and create a key in the API console. Keys start with sk-popnow- and use the same credits as the website.
2. Send the request. POST /jobs/createTask with model openai/gpt-image-2/text-to-image and an input object that follows the parameter table. The response returns a task ID straight away.
3. Get the result. Poll GET /jobs/recordInfo with the task ID, or pass a callBackUrl and we post the result to it. Download the output links when the task succeeds.

# 1. Create the task. Keep the Idempotency-Key if you retry after a network error.
export IDEMPOTENCY_KEY="$(uuidgen)"
curl -X POST https://api.popnow.ai/api/v1/jobs/createTask \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $IDEMPOTENCY_KEY" \
  -d '{
  "model": "openai/gpt-image-2/text-to-image",
  "input": {
    "prompt": "A ceramic teapot on a linen cloth, soft window light, muted palette",
    "aspect_ratio": "1:1",
    "resolution": "1k",
    "quality": "medium",
    "num_outputs": 1,
    "output_format": "png"
  }
}'

# 2. Copy data.taskId from the response, then poll until state is succeeded, failed, canceled or expired.
TASK_ID="TASK_ID_FROM_RESPONSE"
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
  -H "Authorization: Bearer $POPNOW_API_KEY"

Replace the prompt and any links with your own. The API tab has the response, polling and callback reference.
