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:
