Benchmarking GPT‑5 Performance
GPT‑5 marks a step change for Al in the enterprise, evolving ChatGPT from an assistant into a trusted PhD-level expert in every employee's pocket.
What’s new
One powerful model for every task-no model selection, no setup.
Smarter across the board sets a new state-of-the-art across math (99.6% on AIME 2025 with tools), real-world coding (74.9% on SWEBench), and multimodal understanding (84.2% on MMMU)
Significantly fewer hallucinations with -45% less likely to contain a factual error than GPT‑4o.
Faster, more efficient answers 50-80% less output tokens across capabilities compared to o3.
Higher-quality responses using content from your company knowledge and apps.
Natural, helpful tone that feels less like Al and more like collaborating with a thoughtful colleague.
GPT‑5 is smarter and more reliable at tasks businesses rely on like writing, research, analysis, coding, and problem-solving. That means your teams can trust GPT‑5 to handle harder work with higher confidence.
Impact from GPT‑5 deployments
Save time
Offload tasks that take up hours of your team's day, so they can spend time on higher-impact work.
"GPT‑5 is showing real promise, especially when it comes to writing code and handling technical tasks like those needed in order to automate workflows. In one case, the model in ChatGPT even helped us accomplish a very strategic task that would have taken 2-3 weeks to just a couple of hours, with amazing proactivity. GPT‑5 a/so stood out for its speed and handling of Spanish, beating older models on accuracy and working twice as fast."
- Elena Alfaro, Head of Global Al Adoption, BBVA
Move faster
Move from idea to execution in minutes, not hours. Let every team unblock itself.
''At Lowe's, we’re focused on bringing advanced Al to our associates so they can help our customers solve problems and fulfill dreams. With GPT‑5, corporate teams now have access to an ideal balance of reasoning and responsiveness for tasks like planning, analysis, research, and multi-step workflows. We’re thrilled that GPT‑5 delivers richer, more context-aware responses that give them the feeling of working alongside an Al-powered personal assistant."

How to evaluate GPT‑5 for your business
Subject-matter expertise Run tasks across multiple functions-e.g., drafting legal text, producing market analysis, debugging a codebase-then compare GPT‑5's output quality, completeness, and time saved against human benchmarks.
Reliable and fast responses Give GPT‑5 fact-based and multi-step tasks; check factual accuracy, citation quality, and how well it handles clarifications. Measure average response time across low, medium, and high complexity prompts.
Advanced reasoning built in Give the model a complex, ambiguous problem that requires multi-step reasoning with minimal guidance. Assess its solution quality, relevance of follow-up questions, and real-world application.
Understands your company context Upload multiple internal files or connect your company's apps (e.g., Google Drive, SharePoint, GitHub), then evaluate how well GPT‑5 synthesizes answers using your latest content, internal terminology, and guidelines.
