The Next Generation of OpenAI on Azure
As of March 2026, the GPT-5.4 family (Thinking, Pro, Mini) is generally available on Azure Foundry. It brings native tool calling combined with profound system-2 reasoning capabilities.
Key GPT-5.4 Features
- 1 Million Token Context Window: Process entire repositories or massive document sets at once.
- Computer Use: GPT-5.4 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 GPT-5.4 on Azure Foundry provides:
- VNet Integration: End-to-end private networking. Your prompts never traverse the public internet.
- Provisioned Throughput (PTU): Reserve dedicated GPT-5.4 capacity so your latency remains stable even during peak global usage.
- Integrated PII Redaction: Combine GPT-5.4 with Azure's native PII detectors to scrub sensitive data before the prompt reaches the model.
