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.

Comfy Cloud
Comfy Cloud delivers the full functionality of ComfyUI, a node-based visual generative-AI workflow engine, directly in the browser with no setup required. It works anywhere instantly, giving users access to the most powerful server GPUs (such as A100/40 GB) while maintaining stability and performance. All popular open and closed source models (e.g., Stable Diffusion 1.5/SDXL, Qwen-Image, ByteDance SeeDream4.0, Ideogram, Moonvalley) and pre-installed custom nodes are ready to use, while the platform is kept continuously up to date and the underlying infrastructure is managed for you. Users pay only for GPU runtime, not idle time, so editing, setup, and downtime aren’t billed. It supports browser-based creation on any device, handles workflows at scale, and simplifies team deployment with enterprise-grade features such as priority queuing, dedicated resources, and organizational plans.

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.
