OpenAI's flagship multimodal assistant powered by GPT-6 and GPT-5.6 for reasoning, coding, and deep research.
Automatically routes prompts or lets users select between Instant responses and Medium, High, or Extra High thinking depth across GPT-5.6 Luna, GPT-5.6 Sol, and flagship GPT-6 Pro/Astra models.
Asynchronous software engineering and task agents that clone repositories, run terminal tests in sandboxed environments, resolve complex bugs, and submit pull requests.
Browses dozens of primary web sources, academic papers, and connected workspace documents over several minutes to compile structured, citation-backed analytical reports.
Provides a split-screen editor for inline prose and code revisions alongside low-latency voice conversations with live screen and camera grounding.

One REST endpoint for SD 1.5, SDXL, Flux and 10,000+ community models
One POST endpoint handles text-to-image, image-to-image and editing jobs across SD 1.5, SDXL, Flux, ControlNet and LoRA models, with cURL, Python and Node samples for each model.
Thousands of community checkpoints and LoRAs, including anime, photorealistic and stylized families, are browsable with their parameters and sample code.
Requests return a job id or track id so long-running generations can be polled or pushed to your own webhook endpoint instead of blocking the client.
Dreambooth-style endpoints let you train custom concepts and styles on your own images, then reuse the resulting model ids in generation calls.
