GPT-4

GPT-4 is OpenAI's flagship large language model released in March 2023 — the model that brought multimodal frontier AI to mainstream enterprise use. The original GPT-4 introduced a step-change improvement over GPT-3.5: dramatically better reasoning, instruction-following, coding ability, and reliability on professional benchmarks. GPT-4 reportedly passed the Uniform Bar Exam in the top 10% of test-takers and scored at or near the top on AP exams, the SAT, GRE, and many medical and legal licensing tests. Available context windows expanded over time from 8K to 32K to 128K tokens with GPT-4 Turbo. GPT-4 became the foundation for ChatGPT Plus, Microsoft Copilot, and countless enterprise integrations through the OpenAI API and Azure OpenAI Service. The model spawned a wave of follow-on variants and has been largely superseded for new deployments by GPT-4o, GPT-4 Turbo, and the o-series reasoning models. AI governance, AI compliance, and AI risk management programs continue to inventory GPT-4-class deployments — supporting responsible AI through model version tracking in enterprise AI portfolios.
