GPT-Image-2.5 Sunburst
GPT-Image-2.5 Sunburst is an image-generation and editing model available through the OpenAI API. Developers can send text prompts and image inputs to generate new visuals or revise existing images, and can select quality levels ranging from low to max. The model is intended for workflows that need precise edits, including campaign creative and polished product imagery. It can be called through the Images API for direct image creation and editing, or as the image-generation tool in the Responses API. Teams can incorporate it into their own products, creative applications, and automated visual workflows. Usage is billed by token consumption: text input, image input, and generated image output have separate rates, with lower rates available for batch processing and cached inputs.

GPT-Image-2.5 Flare
GPT-Image-2.5 Flare is a hosted image-generation model available through the OpenAI API. It accepts text prompts and image inputs and produces image outputs. Developers can call it through the Images API to generate images or edit supplied images, or use it as an image-generation tool within Responses API workflows that support conversations and multiple steps. Requests can set image quality to low, medium, high, xhigh, max, or auto, and configure output size, format, and compression. OpenAI positions Flare for fast, everyday image generation, while its GPT-Image-2.5 Sunburst model is intended for workflows prioritizing precise editing. The model is designed for developers and organizations adding image creation or editing to their own applications. Access requires API credentials, and usage is billed by tokens, with rates depending on text or image input, image output, and standard or batch processing.

FLUX.2 [klein]
FLUX.2 [klein] is the fastest member of the FLUX.2 family of AI image models, designed to unify text-to-image generation, image editing, and multi-reference composition into a single compact architecture that delivers state-of-the-art visual quality at sub-second inference times on modern GPUs, making it suitable for real-time and latency-critical applications. It supports both generation from prompts and editing existing images with references, combining high diversity and photorealistic outputs with extremely low latency so users can iterate quickly in interactive workflows; distilled versions can produce or edit images in under 0.5 seconds on capable hardware, and even compact 4 B variants run on consumer GPUs with about 8–13 GB of VRAM. The FLUX.2 [klein] family comes in different variants, including distilled and base versions at 9 B and 4 B parameter scales, giving developers options for local deployment, fine-tuning, research, and production integration.
