GPT Image 2.6 on SandBase
GPT Image 2.6 comes in two flavours, each with a text-to-image and an Edit endpoint.
- Sunburst: prioritises detail and precision for complex generation. Sunburst Edit keeps results consistent across successive edits.
- Flare: fast, high-quality generation with improved layout for posters, product imagery and other professional visuals. Flare Edit handles fast edits and multi-image composition.
The previous version is on GPT Image 2.5. Every GPT Image model is on GPT Image API.

Create an API key
Sign in to the SandBase Console and create a key on the API Keys page. Keep it in an environment variable and never commit it to source control.
TERMINALexport SANDBASE_API_KEY="YOUR_SANDBASE_API_KEY" - 02
Submit a run
Send a request to the Unified Run API with model openai/gpt-image-2.6-sunburst. Only the model field changes between models on this page.
TERMINALcurl https://api.sandbase.ai/v1/run \ -H "Authorization: Bearer $SANDBASE_API_KEY" \ -H "Content-Type: application/json" \ -d '{"model": "openai/gpt-image-2.6-sunburst", "prompt": "A clean product poster for a lime-green glass water bottle, bold headline \"STAY SHARP\", studio lighting"}' - 03
Read the output
This model runs synchronously, so the response already contains the output URL. Open the model in the Playground to adjust parameters.
Questions, answered
Sunburst or Flare?
Use Sunburst when detail and precision matter most. Use Flare for speed and layout-heavy work such as posters and product shots.
What changed from GPT Image 2.5?
Flare improves layout quality for professional visuals, and Sunburst Edit improves consistency across successive edits.
Can GPT Image 2.6 combine several images?
Yes. Flare Edit supports multi-image composition.
Is GPT Image 2.6 synchronous?
Sunburst text-to-image returns the image in the same response. Check each model page for its execution mode.
