OpenAI's image models
GPT Image models follow detailed instructions, render text and handle iterative edits. Each version comes in two flavours with a matching Edit endpoint.
- Sunburst: prioritises detail, precision and consistency across successive edits.
- Flare: fast, high-quality generation and multi-image composition. GPT Image 2.6 Flare improves layout for posters and product imagery.
- GPT Image 2: the most used GPT Image model on SandBase, with strong fine-grained editing.
Version pages: GPT Image 2.6 and GPT Image 2.5. For OpenAI language models, see GPT 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-flare. 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-flare", "prompt": "A clean product poster for a lime-green glass water bottle, bold headline \"STAY SHARP\", studio lighting"}' - 03

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 precision matters most, and Flare for fast generation and multi-image composition. A common workflow is to explore with Flare and refine with Sunburst.
What changed in GPT Image 2.6?
GPT Image 2.6 Flare improves layout quality for posters and product imagery. 2.6 Sunburst Edit improves consistency across successive edits.
Should I still use GPT Image 2?
Yes, if your workflow is tuned for it. It remains the most used GPT Image endpoint on SandBase.
Can GPT Image edit with several images?
Yes. The Edit endpoints support multi-image synthesis and composition.
