In 1590, Hans Lippershey built the first microscope—suddenly, we could see what had always been there, just beyond perception. Today, we’re releasing two new OpenAI models in Azure AI Foundry that do something similar for reasoning:
o3 — Their most advanced model yet, strong in coding, math, science, and visual tasks
o4-mini — Smaller, faster, and remarkably capable in technical domains, at lower cost
For the first time, these models can independently use all #ChatGPT tools—browsing, #Python, image understanding, and generation—unlocking a new class of autonomous workflows.
They don’t just see images—they reason with them. Upload a sketch, diagram, or even a blurry whiteboard, and the model integrates it directly into its problem-solving process.
For developers: both models support parallel tool calling, available in the Responses and Chat Completions APIs. It’s a foundation for the next generation of agentic systems.
