Key features

Photoreal people and light

Fabric sheen, skin texture, shallow depth of field and a named lens and light direction come through clearly.

Text and hex colours

Quote each line of type and say where it sits. Our magazine-cover example rendered a masthead, cover lines and an issue line exactly as written, on a background set by a hex value.

Two size tiers, nine shapes

1k is about one megapixel and 2k reaches 2048 pixels on the long side, from square to 21:9 and 9:21.

Request parameters

ParameterRequiredDescription
seedNoReuse the same number to get a repeatable result. ≥ 0 · ≤ 2147483647
promptYesDescribe the subject, setting, light and style in plain sentences.
resolutionNoOutput size. Bigger sizes look sharper and cost more. 1k · 2k · Default: 1k
aspect_ratioNoThe shape of the frame: wide, square or tall. 1:1 · 16:9 · 9:16 · 4:3 · 3:4 · 3:2 · 2:3 · 21:9 · 9:21 · Default: 1:1

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.

OptionCredits per image≈ USD
resolution 1K10.5$0.11
resolution 2K13.21$0.13

Each task is rounded up to whole credits, so one run at the lowest tier costs 11 credits per image ($0.11).

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

Use cases

Editorial and campaign portraits

Fashion, lifestyle and brand portraits for mood boards, pitch decks and campaign drafts.

Covers, posters and labels

Magazine covers, event posters and packaging where several pieces of text share the frame with an image.

Cinematic stills

Widescreen frames with a described lens, light and grade for storyboards and key art.

Prompt guide & pro tips

Write it like a photo brief

Subject, wardrobe, setting, lens, light direction and grade, as full sentences.

Quote and position all text

Every word that must appear goes in quotes with a position; unquoted words are treated as description.

Give colours as hex values

#0F5C4A for a gown or #4A0E1A for a backdrop is followed more closely than a colour name.

Expect 20 to 90 seconds

Most of our requests finished in that range; 2k and a busy queue take longer.

API quick start

Call the FLUX.2 Max 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 black-forest-labs/flux-2-max/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": "black-forest-labs/flux-2-max/text-to-image",
  "input": {
    "prompt": "A ceramic teapot on a linen cloth, soft window light, muted palette",
    "aspect_ratio": "1:1",
    "resolution": "1k"
  }
}'

# 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.

FLUX.2 Max API questions

What is the model name for FLUX.2 Max in the API?

Put black-forest-labs/flux-2-max/text-to-image for Create Image; black-forest-labs/flux-2-max/edit for Edit Image in the model field of POST /jobs/createTask.

What is FLUX.2 [max]?

It is the top-quality model of Black Forest Labs' FLUX.2 family, released on 16 December 2025. It is aimed at photoreal people and light, readable text in the image and edits that combine several references.

Can it write text into images?

Yes. Our magazine-cover example rendered a masthead, a cover line and an issue line, all spelled as written. Quote each line and say where it sits. Hex colour values in the prompt are followed closely.

How many reference images can I use?

One to three. Refer to them in the prompt as image 1, image 2 and image 3 and say what each one contributes. Our bookshop example placed two women from separate portraits into a third photo of a room.

What does auto do in edits?

With auto the result keeps the shape of the first source image at about one megapixel. Choosing a ratio instead lets you pick 1k or 2k.

Does it search the web or take steps and guidance settings?

No. Those controls are not offered here. You get the prompt, aspect ratio, size tier and seed.

What are the limits of the FLUX.2 Max API?

Resolutions: 1K · 2K; Aspect ratios: 1:1 · 16:9 · 9:16 · 4:3 · 3:4 · 3:2 +3; Prompt length (characters): 5,000. Requests outside these limits are rejected before anything is charged.

Can I try FLUX.2 Max without writing code?

Yes. The Playground runs FLUX.2 Max on your PopNow credits, needs no API key, and shows the matching code for every run.

FLUX.2 Pro is cheaper and faster for everyday work. Max is the one for hero portraits and covers.
