The tempo of AI innovation continues to speed up. Only a few months after the discharge of GPT-5.2 and GPT-5.3, Microsoft Foundry now brings us GPT-5.4—OpenAI’s most succesful frontier mannequin so far to Microsoft Foundry. This launch marks a big leap ahead in reasoning, agentic workflows, and professional-grade automation.
Whether or not you’re constructing AI brokers, automating complicated workflows, or exploring new frontiers in software program improvement and information evaluation, GPT-5.4 is designed to ship sooner, extra dependable, and extra clever outcomes.
What’s in GPT-5.4?
GPT-5.4 introduces a spread of enhancements that elevate its efficiency throughout skilled and enterprise situations:
- Constructed-in agentic workflows for planning and execution
- Native laptop use capabilities (keyboard, mouse, screenshots)
- Device Seek for navigating massive instrument ecosystems
- Help for very large context windows (up to 1,050,000 tokens)
- Improved token effectivity for sooner, lower-cost responses
- Enhanced coding and software program automation reliability
- Larger factual accuracy and decreased hallucinations
These capabilities make GPT-5.4 a strong instrument for doc and spreadsheet creation, coding, information evaluation, and long-form reasoning duties.
Introducing GPT-5.4 Professional
For situations the place analytical depth and completeness are extra essential than latency, Microsoft Foundry additionally provides GPT-5.4 Professional—a premium variant of the mannequin.
GPT-5.4 Professional is designed for deep analytical workflows, corresponding to scientific analysis, strategic decision-making, and sophisticated problem-solving. It introduces:
- Multi-path reasoning analysis to discover various options
- Higher analytical depth for issues with trade-offs or a number of legitimate outcomes
- Improved stability throughout lengthy reasoning chains
- Enhanced choice assist the place rigor outweighs pace
With a bigger context window (400,000 tokens for the time being, bigger context window coming quickly) and the identical excessive output capability (128,000 tokens), GPT-5.4 Professional is the go-to mannequin for high-assurance, high-complexity duties.

Capabilities
That can assist you consider the evolution of those fashions, right here’s a side-by-side comparability of GPT-5.4, GPT-5.4 Professional, and GPT-5.2:
