About

OpenAI is an AI research and product company that develops frontier language, multimodal, and reasoning models and delivers them through APIs, ChatGPT products, and cloud partnerships. For business buyers, the relevant surface is not consumer ChatGPT novelty but the enterprise stack: ChatGPT Enterprise, the API platform, model choices for production apps, admin controls, and deployment patterns that meet security and data-residency needs. Enterprises use OpenAI models to build copilots, document workflows, customer service agents, and developer tools, often via Microsoft Azure OpenAI Service as well as OpenAI’s direct API. Public case patterns include large banks and insurers piloting assistants for employees and customers under strict governance. OpenAI continues to release successive model families (including GPT-series updates) with higher capability and tool use. AI-360 profiles OpenAI as platform infrastructure for AI applications in financial and professional services—not as a how-to for consumer chat.

How they use AI

OpenAI’s product is AI: it trains and serves large models that customers call for generation, reasoning, vision, and tool-using agents. Enterprise buyers access models through the OpenAI API and ChatGPT Enterprise, with admin, SSO, and data-usage controls designed so business prompts are not used to train consumer models under stated enterprise terms. Typical production patterns include retrieval-augmented generation over internal knowledge, structured extraction from documents, code assistance, and multi-step agents that call tools and APIs. Microsoft Azure OpenAI Service packages the same model families inside Azure compliance boundaries for regulated industries. Named financial-services programmes (for example large European and Japanese banks reported as enterprise customers) illustrate employee assistants and productivity use cases, always under customer governance. Buyers must still implement evaluation, human oversight, and policy controls; model capability alone is not a control framework. Product names and model IDs change frequently—pin versions in production.
