Is GPT Image 2.5 free to use?

GPT Image 2.5 is available to all ChatGPT users, including the free tier. However, higher-quality settings and the Sunburst variant (via API) are only accessible on paid plans or through direct API access, which is billed at $30 per million output image tokens.

What is the difference between GPT-Image-2.5 Flare and Sunburst?

Flare is the default variant, optimized for speed — up to 50% faster than GPT Image 2.0 — and suitable for high-volume generation and rapid prototyping. Sunburst is the precision variant, running approximately 1.5–2x slower but delivering tighter consistency for multi-turn editing and production-quality work. Both are priced identically.

When should I use a dedicated image-to-image tool instead of ChatGPT Images 2.5?

If your task starts from a specific reference image that must stay visually anchored — product photography, character consistency across a batch, or combining elements from multiple source images — a tool designed specifically for image-to-image workflows handles that constraint more directly. GPT Image 2.5 excels at iterative creative work inside ChatGPT's assistant interface; a dedicated tool is better when the reference image is the design constraint, not just a starting point.
