OpenAI o1 & OpenAI o3-mini on Foundry — Azure AI Foundry Architecture & Agent Service

The Latest OpenAI Models on Azure

GPT-4o & OpenAI o1 on Azure AI Foundry

OpenAI o1 became Generally Available on Azure Foundry on April 23, 2026. It is OpenAI's omnimodal frontier model featuring a 1M context window and pricing at $5 / $30 per MTok (input / output). As of June 1, 2026, OpenAI o1 is also available on Amazon Bedrock, making it the first OpenAI model deployed across both major cloud platforms simultaneously.

OpenAI o3-mini - Reasoning Powerhouse (March 2026)

The OpenAI o3-mini family (Thinking, Pro, Mini) is generally available on Azure Foundry. It brings native tool calling combined with profound system-2 reasoning capabilities.

Key Features Across GPT-4o

• 1 Million Token Context Window: Process entire repositories or massive document sets at once.
• Computer Use: OpenAI o3-mini+ can analyze screenshots, navigate UI, and execute multi-step tasks natively.
• Dynamic Tool Search: Reduces token overhead and inference costs by intelligently loading only the necessary tools for a specific task.

Azure-Specific Deployments

Unlike the public OpenAI API, deploying OpenAI o1/5.4 on Azure Foundry provides:

• VNet Integration: full private networking. Your prompts never traverse the public internet.
• Provisioned Throughput (PTU): Reserve dedicated OpenAI o1/5.4 capacity so your latency remains stable even during peak global usage.
• Integrated PII Redaction: Combine with Azure's native PII detectors to scrub sensitive data before the prompt reaches the model.
