Generate images from text with GPT Image 2.5 Sunburst, the higher-precision tier for detailed creative work. Coming soon — no subscription.
关于此模型
GPT Image 2.5 Sunburst Text to Image is OpenAI's newest image model, announced September 8, 2026, generating high-fidelity images from detailed text prompts with sharper detail, richer textures, and up to 50% lower latency than GPT Image 2. GPT-Image-2.5 Sunburst is OpenAI's higher-precision tier, trading longer generation times for an extra level of precision on detailed creative work. Muapi is bringing GPT Image 2.5 online as soon as OpenAI opens general API access. See GPT Image 2.5 Flare for the faster tier.

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, resolution, and quality — once live, call the endpoint below and poll for the result:
curl -X POST https://api.muapi.ai/api/v1/gpt-image-2.5-sunburst-text-to-image \
-H "x-api-key: YOUR_API_KEY" \
-H "Content-Type: application/json" \

GPT Image 2.5 is OpenAI's newest image model, announced September 8, 2026, powering ChatGPT Images 2.5 and two new API models: GPT-Image-2.5 Flare and GPT-Image-2.5 Sunburst.
Not yet. This endpoint is in early access with OpenAI. Muapi will enable it as soon as general API access opens — no action needed on your part.
Sunburst trades longer generation times for an extra level of precision on detailed creative work. Use [GPT Image 2.5 Flare](/playground/gpt-image-2.5-flare-text-to-image) if you need the faster tier instead.
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.
Yes. [GPT Image 2](/playground/gpt-image-2-text-to-image) text-to-image and image editing are live now while GPT Image 2.5 is in development.
Create a free Muapi account and API key today — the gpt-image-2.5-sunburst-text-to-image endpoint will activate automatically for existing users once OpenAI opens general availability.
