What is GPT-5.4-Pro?

GPT-5.4-Pro is the highest-capability API variant of the GPT-5.4 model family, designed for extremely complex reasoning, research, coding, and enterprise automation tasks.

Compared with the standard GPT-5.4 model, GPT-5.4-Pro uses significantly more internal compute to โ€œthink harderโ€ before producing responses, which leads to more accurate and reliable outputs for difficult problems.

The model is optimized for professional workloads such as financial analysis, software engineering, scientific research, and large-scale document reasoning.

Main Features of GPT-5.4-Pro

  • Extreme reasoning performance: Uses additional compute to produce more precise answers on complex tasks.
  • 1.05M token context window: Enables analysis of extremely large documents, datasets, or entire repositories.
  • Configurable reasoning depth: Developers can control reasoning effort levels (medium, high, xhigh).
  • Advanced tool orchestration: Works with web search, file retrieval, and other tools through the Responses API.
  • Long-running reasoning support: Complex tasks may take minutes to complete due to deeper compute allocation.
  • Enterprise reliability: Designed for high-stakes workflows requiring maximum answer accuracy.

Benchmark Performance

OpenAI reports significant improvements in professional reasoning benchmarks with GPT-5.4 models:

BenchmarkGPT-5.4GPT-5.2
GDPval (knowledge work)83.0%70.9%
OfficeQA68.1%63.1%
Investment Banking Modeling87.3%71.7%

These improvements highlight GPT-5.4โ€™s stronger performance on complex professional knowledge tasks and analytical reasoning workflows.

GPT-5.4-Pro further improves reliability by allocating more reasoning compute than the standard GPT-5.4 model.

GPT-5.4-Pro1.05M tokensMaximum reasoning accuracy
GPT-5.41.05M tokensBalanced speed and capability
o3-proSmallerEfficient reasoning
Gemini 3 Pro~1M tokensStrong multimodal capabilities

Key takeaway:
Use GPT-5.4-Pro when maximum reasoning accuracy matters more than latency or cost.

Limitations

  • Higher latency due to deeper reasoning compute
  • More expensive than standard GPT-5.4
  • No audio or video generation
  • Some long tasks may take minutes to complete
