The pace of AI innovation continues to accelerate. Just a few months after the release of GPT-5.2 and GPT-5.3, Microsoft Foundry now brings us GPT-5.4—OpenAI’s most capable frontier model to date to Microsoft Foundry. This release marks a significant leap forward in reasoning, agentic workflows, and professional-grade automation.
Whether you’re building AI agents, automating complex workflows, or exploring new frontiers in software development and data analysis, GPT-5.4 is designed to deliver faster, more reliable, and more intelligent results.

What’s in GPT-5.4?
GPT-5.4 introduces a range of enhancements that elevate its performance across professional and enterprise scenarios:
Built-in agentic workflows for planning and execution
Native computer use capabilities (keyboard, mouse, screenshots)
Tool Search for navigating large tool ecosystems
Support for very large context windows (up to 1,050,000 tokens)
Improved token efficiency for faster, lower-cost responses
Enhanced coding and software automation reliability
Higher factual accuracy and reduced hallucinations
These capabilities make GPT-5.4 a powerful tool for document and spreadsheet creation, coding, data analysis, and long-form reasoning tasks.
Introducing GPT-5.4 Pro
For scenarios where analytical depth and completeness are more important than latency, Microsoft Foundry also offers GPT-5.4 Pro—a premium variant of the model.
GPT-5.4 Pro is designed for deep analytical workflows, such as scientific research, strategic decision-making, and complex problem-solving. It introduces:
Multi-path reasoning evaluation to explore alternative solutions
Greater analytical depth for problems with trade-offs or multiple valid outcomes
Improved stability across long reasoning chains
Enhanced decision support where rigor outweighs speed
With a larger context window (400,000 tokens at the moment, larger context window coming soon) and the same high output capacity (128,000 tokens), GPT-5.4 Pro is the go-to model for high-assurance, high-complexity tasks.
Capabilities
To help you evaluate the evolution of these models, here’s a side-by-side comparison of GPT-5.4, GPT-5.4 Pro, and GPT-5.2:
Pricing and Availability
Microsoft Foundry offers flexible pricing for GPT-5.4 based on context length:
GPT‑5.4 (<272K input tokens):
$2.50 per million input tokens
$0.25 per million cached input tokens
$15.00 per million output tokens
GPT‑5.4 (>272K input tokens):
$5.00 per million input tokens
$0.50 per million cached input tokens
$22.50 per million output tokens
GPT‑5.4 Pro:
$30.00 per million input tokens
$180.00 per million output tokens
At launch, GPT-5.4 is available in Standard Global and Standard Data Zone (US), while GPT-5.4 Pro is available in Standard Global, with more deployment options expected soon.
Thoughts
GPT-5.4 is a great leap forward in enterprise AI. With its massive context window, built-in agentic capabilities, and native computer interaction, it’s built for the next generation of professional work. And for those who need even more analytical depth, GPT-5.4 Pro offers unmatched reasoning power.
The future of AI in the enterprise is arriving faster than ever—and Microsoft Foundry is making it easier to adopt and scale these capabilities securely and efficiently.
