What Was ChatGPT4o? (Historical Overview)
Launched as an independent third-party web interface, ChatGPT4o provided users with browser-based access to conversational AI models. It targeted users looking for quick, no-fuss interaction mimicking official OpenAI interfaces, but relied entirely on third-party API reselling or proxying.
How to Replace ChatGPT4o (Migration Guide)
