Overview
OpenAI, Inc aims to create "safe and beneficial" artificial general intelligence, defined as highly autonomous systems that outperform humans at most economically valuable work. The organization leads today's AI boom with some of the world's most advanced multimodal foundation models—including GPT‑4o, its real‑time "omni" flagship—and continues to compress state‑of‑the‑art performance into smaller, cheaper variants like GPT‑4o‑mini. The latest GPT‑4o‑transcribe models replace Whisper for speech tasks, while GPT‑Image‑1 overtakes DALL·E 3 with native image generation and editing.Key Azure AI Foundry Models (July 2025)
- GPT‑4o – Best‑in‑class reasoning, code, audio & vision in one API.
- GPT‑4o‑mini – Small‑footprint 20B model that outperforms GPT‑3.5‑Turbo at half the cost.
- GPT‑4o‑transcribe / TTS – Upgraded speech models with lower error rates and customizable voices.
- GPT‑Image‑1 – Next‑gen text‑to‑image + in‑painting that supersedes DALL·E 3.
