The DevDay ChatBot is a GPT developed by OpenAI. It offers users the opportunity to inquire about events and materials covered during the DevDay Conference. This interactive platform uses the powerful language model, ChatGPT, to generate accurate responses to user queries. The service aims to offer useful insights and recap on discussions, speeches, presentations and key announcements that were made during the conference. In addition to events specifically tied to the DevDay Conference, the DevDay ChatBot is also equipped to explain concepts related to GPT such as the Assistants API and GPT-4 turbo, thereby providing an educating and clarifying experience for the users. This all-encompassing versatility makes it a valuable tool for those seeking an in-depth understanding of the conference or for those wanting to catch up on details they might have missed.
