GPT-4
Also: ChatGPT
OpenAI's flagship model family — the most widely deployed AI models in enterprise contexts and the benchmark most organizations compare against when evaluating alternatives. GPT-4o (multimodal), GPT-4 Turbo, and related variants all fall under this family. Strong across coding, reasoning, and language tasks. Available via OpenAI's ChatGPT product and API, as well as Microsoft's Copilot integrations across Office 365.
In practice
GPT-4 is OpenAI's flagship model — the most widely known AI outside Anthropic's Claude. If you're comparing options for a business use case, GPT-4 (and its successors) and Claude are the two most common choices. The decision usually comes down to specific task performance, pricing, and which API ecosystem your team prefers.
