How to Use GPT Image 2.5 Flare Text to Image

Write your prompt — describe the subject, style, lighting, and composition. GPT Image 2.5 follows complex, multi-part instructions more reliably than GPT Image 2.
Set aspect_ratio and resolution — then call the endpoint below and poll for the result:

curl -X POST https://api.muapi.ai/api/v1/gpt-image-2.5-flare-text-to-image \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "A hyperrealistic portrait of an astronaut on Martian dunes at golden hour", "aspect_ratio": "16:9", "resolution": "2K"}'

Poll for the result using the returned request_id against /api/v1/predictions/{id}/result until status is completed.

Common Questions

Frequently asked

What is GPT Image 2.5?

GPT Image 2.5 is OpenAI's newest image model powering ChatGPT Images 2.5 and two new API models: GPT-Image-2.5 Flare and GPT-Image-2.5 Sunburst.

Is GPT Image 2.5 available on Muapi now?

Yes. GPT-Image-2.5 Flare and GPT-Image-2.5 Sunburst are both live on Muapi for text-to-image and image editing.

Why choose Flare over Sunburst?

Flare is the default, fastest tier with the same quality and editing gains as GPT Image 2.5. Use [GPT Image 2.5 Sunburst](/playground/gpt-image-2.5-sunburst-text-to-image) if you need the higher-precision tier instead.

How is GPT Image 2.5 different from GPT Image 2?

GPT Image 2.5 has better reference-photo fidelity, more precise single-element editing, more reliable multi-turn consistency, and up to 50% lower generation latency than GPT Image 2.

Can I use a GPT Image API on Muapi today?

Yes. [GPT Image 2](/playground/gpt-image-2-text-to-image) and GPT Image 2.5 (Flare and Sunburst) are all live on Muapi today.

How do I start using GPT Image 2.5 on Muapi?

Create a free Muapi account and API key, then call the `gpt-image-2.5-flare-text-to-image` endpoint directly — no waitlist or approval step required.
