Basic Information

• Release Date: On October 9, 2025, OpenAI officially launched the GPT-5 Pro API for developers, available exclusively to Pro subscription users.
• Pricing Standard: The per-token input price is $0.000015, or $15 per million tokens.
• Positioning: As a replacement for OpenAI’s o3-pro, it targets high-end enterprise and professional user markets.

Core Features

• Context Processing: Supports a context window of 400,000 tokens, equivalent to processing 300,000 words—enough to handle an entire book or a complete legal case file in one go.
• Multi-modal Capability: Supports dual-modal input of text and images, enabling analysis of specialized materials such as medical imaging and engineering drawings.
• Accuracy Performance: The rate of major errors has decreased by 22% compared to the previous generation, and the factual error rate is 45% lower than GPT-4o; 67.8% of external experts prefer its responses.

Technical Highlights

• Dynamic Routing Architecture: Intelligently allocates computing resources, improving response speed for complex reasoning tasks by 60% over the previous generation. The priority processing layer can reduce latency to within 800 milliseconds.
• Parallel Inference Technology: Supports scalable inference capabilities, achieving a score of 88.4% on the GPQA scientific knowledge benchmark and a high score of 84.2% on the MMMU multi-modal test.
• Developer Support: Provides a service health dashboard, allowing developers to monitor runtime metrics such as response times in real time.

Market Impact

• Industry Position: After launch, it has topped the large-model competition arena, ranking first in fields such as mathematics and coding. 92% of Fortune 500 companies are already using its enterprise-level services.
• Competitive Advantage: Its 400,000-token context capability doubles that of Anthropic Claude 4 Opus, and its dynamic routing architecture is 60% faster than Google Gemini 2.5 Pro.

Application Scenarios

• Legal Field: Completes contract reviews that would normally take three lawyers two days in just eight minutes; identifies risks in 100,000-word merger and acquisition contracts in five minutes.
• Financial Field: Reduces the processing time for four-hour risk control reports to just 12 minutes, with an error rate reduced by 42%.
• Research and Medical Field: Completes two weeks’ worth of literature review in three hours; improves the accuracy of medical-assisted diagnosis by 28% compared to single-text analysis.
