• Coding: 74.9% on SWE-bench Verified (real-world software engineering tasks)
• Visual Understanding: 84.2% on MMMU (multimodal comprehension)
• Health Knowledge: 46.2% on HealthBench Hard (medical reasoning scenarios)

These metrics demonstrate GPT-5's capability to handle expert-level tasks across industries relevant to U.S. knowledge workers, from healthcare professionals to software developers.

Real-World Knowledge Work Performance

Perhaps most impressive is GPT-5's performance on OpenAI's internal GDP-val benchmark, which measures capability on economically valuable knowledge work tasks. GPT-5 with reasoning capabilities matched or exceeded expert human performance in approximately 70-74% of cases across over 40 occupations including law, engineering, logistics, and sales.

Key Features That Distinguish GPT-5 From Previous Models

Enhanced Writing Capabilities

GPT-5 serves as OpenAI's most capable writing collaborator, transforming rough ideas into compelling, resonant content with literary depth. The model handles complex writing structures including unrhymed iambic pentameter and naturally flowing free verse, making it invaluable for American professionals drafting reports, proposals, and communications.

Advanced Coding Functionality

For U.S. developers, GPT-5 represents a breakthrough in AI-assisted programming. The model excels at complex frontend generation, debugging large repositories, and creating functional websites, apps, and games from single prompts. Early testers specifically praised its understanding of design elements like spacing, typography, and aesthetic sensibility.

Health Information Support

GPT-5 achieves the highest scores on HealthBench evaluations, designed around realistic healthcare scenarios and physician-defined criteria. The model acts as an active thought partner for health-conscious Americans, proactively flagging concerns and adapting responses to user context, knowledge level, and geography—though OpenAI emphasizes it doesn't replace medical professionals.

Reduced Hallucinations and Improved Reliability

One of GPT-5's most significant improvements addresses a persistent AI challenge: factual accuracy. With web search enabled, GPT-5 produces responses approximately 45% less likely to contain factual errors compared to GPT-4o. When using its reasoning capabilities, that improvement jumps to roughly 80% fewer errors compared to OpenAI's o3 model.

For U.S. businesses and professionals relying on AI for decision-critical information, this reliability enhancement represents a major step forward in trustworthy AI deployment.

The "Capability Overhang" Concept: Why Adoption Matters

During his December 2025 interview, Sam Altman introduced a crucial concept: the "capability overhang." This refers to the gap between what AI models can already do and what users are actually using them for. Even Altman himself admitted running his workflow "in very much the same way" despite knowing he could leverage AI far more extensively.

For American professionals, this represents both a challenge and an opportunity. Early adopters who optimize workflows around current AI capabilities can gain significant productivity advantages before mainstream adoption closes that gap.

ChatGPT App Ecosystem: The Platform Play

Alongside model improvements, OpenAI opened ChatGPT to third-party app developers in late 2025, creating what may become the largest app platform launch in tech history. With 900 million monthly active users—vastly exceeding the 6 million iPhone users when Apple's App Store launched—ChatGPT now serves as a distribution platform for AI-native applications.

U.S. developers can now submit apps that integrate directly into ChatGPT conversations, enabling actions like ordering groceries, creating presentations, or searching apartments without leaving the chat interface. This represents a fundamental shift from AI as a tool to AI as a platform.

Privacy and Safety: OpenAI's Approach to Responsible AI

GPT-5 introduces "safe completions" training, a new approach that moves beyond simple refusal-based safety. Instead of only complying or refusing requests, the model now provides the most helpful answer possible while staying within safety boundaries. For dual-use questions—particularly relevant to U.S. researchers in fields like virology—GPT-5 can answer at appropriate detail levels while transparently explaining any limitations.
