The Reddit AMA features the Codex team from OpenAI, inviting users to ask questions about Codex, their coding agent designed to perform tasks in various environments, including terminals, IDEs, and the ChatGPT iOS app. They recently introduced a new model, gpt-5-codex, which is optimized for agentic coding. The AMA takes place on Wednesday, September 17th, from 11:00 AM to 12:00 PM PT. The Codex team members participating include Sam Arnesen, Ed Bayes, Alexander Embiricos, Eason Goodale, Pavel Krymets, Thibault Sottiaux, Joseph Trasatti, and Hanson Wang. In the responses section, several related links provide additional information about Codex, such as its features, latest updates, best practices for using it in IDEs, integration with local LLMs, and recommendations for plugins. This setup allows users to get a deeper understanding of Codex and how to leverage it effectively for their coding needs. The AMA format encourages direct interaction, making it a valuable opportunity for those interested in the capabilities and applications of OpenAI's Codex.
