API Endpoint

POSThttps://api.segmind.com/v1/gpt-image-2.5-flare

Parameters

promptrequired
string

Text describing the image. Supports in-image typography across scripts — lead with subject, style, lighting.

Default: "A photoreal product photograph of a frosted glass bottle of artisanal hot sauce standing on a weathered wooden market stall, with three fresh red habanero peppers and a halved lime beside it. The wraparound kraft-paper label reads, in bold condensed serif lettering: 'EMBER & ASH' across the top, 'Smoked Habanero Hot Sauce' as the tagline beneath it, a small legible line 'habanero · smoked paprika · lime · sea salt', and '148 ml' in the lower corner. Condensation beads on the glass, a red wax-sealed cork, visible paper grain on the label, bright even daylight."
backgroundoptional
string

"Opaque" renders a filled background; "Transparent" returns a PNG or WEBP with an alpha channel; "Auto" lets the model decide.

Default: "opaque"
Allowed values :
Opaque"opaque"
Transparent"transparent"
Auto"auto"
image_urlsoptional
string[]

Optional reference images to edit or draw context from. Providing any image switches to edit mode.

Default: []
mask_image_urloptional
string (uri)

Optional mask for surgical inpainting, used only alongside a reference image. Must be a PNG with an alpha channel, matching the reference image's dimensions: the transparent areas are regenerated, everything opaque stays pixel-perfect. A flat black-and-white mask with no alpha channel is rejected.

moderationoptional
string

Content filter strictness. "Auto" is the safe default.

Default: "auto"
Allowed values :
Low"low"
Auto"auto"
output_compressionoptional
integer

Compression level 0-100. 100 preserves text crispness; lower values reduce file size.

Default: 100Range: 0 - 100
output_formatoptional
string

"PNG" for crisp text, "WEBP" for smaller size, "JPEG" for broad compatibility.

Default: "png"
Allowed values :
PNG"png"
JPEG"jpeg"
WEBP"webp"
qualityoptional
string

Rendering fidelity. "High" keeps typography crisp; use lower values only for previews.

Default: "high"
Allowed values :
Low"low"
Medium"medium"
High"high"
Auto"auto"
sizeoptional
string

Output resolution (WIDTHxHEIGHT). Each edge must be a multiple of 16, aspect ratio between 1:3 and 3:1, longest edge at most 3840, and total pixels between 655,360 and 8,294,400. "Auto" lets the model pick.

Default: "1024x1536"
Allowed values (13 total):
"1024x1024""1536x1024""1024x1536""1280x960""960x1280""1536x864""864x1536""2048x2048""2048x1152""1152x2048"+3 more

Response Type

Returns: Text/JSON

Asynchronous requests (v2)

Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.

  1. 1
    POST /v2/gpt-image-2.5-flare

    Submitreturns request_id, status_url, response_url

  2. 2
    GET /v2/requests/{id}/status

    Polluntil COMPLETED or FAILED

  3. 3
    GET /v2/requests/{id}

Status states

QUEUEDAccepted, waiting for a worker
PROCESSINGRunning on a worker
COMPLETEDDone — result body is ready
FAILEDErrored (incl. content/RAI blocks)
  • A FAILED request is served as HTTP 422 — the body still carries the error detail.
  • An unknown or expired request_id returns HTTP 404.
  • Results are retained for 1 hour, then expire.
  • Content / RAI blocks surface as FAILED, not a separate state.
  • Track completion by polling the status endpoint.
