Tibo confirmed that OpenAI plans to merge Codex and ChatGPT capabilities, with the goal of making the experience less complex for users:
“…and for Codex and ChatGPT, we have Chat and the Work toggle, and we’re going to merge them. We’ve heard the feedback loud and clear: people love the capabilities in Work, but sometimes you want to use Chat because it’s a little faster and more pleasant to use. So we’re merging the two and reducing that complexity.”
