GPT-5

What is the GPT-5 API?

GPT‑5 is OpenAI’s most advanced and unified AI model, combining fast, real-time responsiveness with deep reasoning capabilities. It supports multimodal inputs—including text, image, audio, and video—and features a dynamic architecture that switches between quick-answer and “thinking” modes based on prompt complexity. With improved accuracy, reduced hallucinations, and expert-level performance in coding, writing, health, and science, GPT‑5 delivers intelligent, context-aware responses across a wide range of tasks.

GPT-5 API is available on the JoJ API marketplace. Subscribe with a single JoJ API key, call it through one gateway, and pay from one wallet — no separate account or contract with the provider.
