On what date did OpenAI release GPT-4?

OpenAI released GPT-4 on March 14, 2023. The company described it as a large multimodal model able to accept text and image inputs, although image-input availability initially depended on product access and was not broadly open to everyone.

GPT-4 followed GPT-3 and GPT-3.5 and was designed to improve reasoning, factual performance, and instruction following. OpenAI reported results on professional and academic benchmarks, while also acknowledging that the model could still produce incorrect or misleading answers.

The release date is sometimes confused with the public launch of ChatGPT, which occurred on November 30, 2022, or with the later launch of GPT-4-powered products. GPT-4’s original announcement was a model release by OpenAI, while access was provided through services such as ChatGPT Plus and the API.
