OpenAI has described GPT‑5 as a unified ChatGPT model intended for immediate enterprise use, with no model selection required. The company presents benchmark results and deployment examples to show how the model could be applied across functions.
Performance and benchmarks
OpenAI reports GPT‑5 achieves 99.6% on AIME 2025 with tools, 74.9% on SWEBench for real-world coding, and 84.2% on MMMU for multimodal understanding. The company states GPT‑5 is 45% less likely to contain a factual error than GPT‑4o and produces 50–80% fewer output tokens across capabilities compared with o3.
OpenAI characterizes GPT‑5 as evolving ChatGPT “from an assistant into a trusted PhD-level expert,” and says the model yields higher-quality responses when using a company’s knowledge and connected apps.
Business use cases and customer feedback
Examples of tasks highlighted include drafting go-to-market plans, building live incident dashboards from plain-English prompts, running finance simulations, and reviewing legal or regulatory changes. OpenAI provides customer quotes attributing faster delivery and improved accuracy: Elena Alfaro, Head of Global AI Adoption at BBVA, described faster code and Spanish handling and a case that reduced a 2–3 week task to a few hours. Seemantini Godbole, CIO at Lowe’s, said GPT‑5 delivered “richer, more context-aware responses” for planning and multi-step workflows. Gene Rapoport, Partner & Co-Head of the Private Equity AI Practice at Bain, noted improved analysis and research for client work.
Enterprise controls and evaluation guidance
OpenAI lists security and governance features including AES-256 encryption at rest, TLS 1.2+ in transit, SAML SSO, SCIM provisioning, role-based access, real-time usage analytics, and data residency in seven global regions. Compliance certifications cited include GDPR, CCPA, CSA STAR, and SOC 2 Type 2.
The company recommends evaluating GPT‑5 by testing subject-matter tasks, measuring factual accuracy and response time, probing multi-step reasoning, and assessing synthesis of internal files or app integrations. For access and deployment, OpenAI directs businesses to contact sales or sign up for ChatGPT Business for immediate GPT‑5 access.
