The introduction of these models coincides with the planned retirement of GPT-4 from ChatGPT on April 30, as OpenAI transitions to the more advanced GPT-4o. Concurrently, updates reveal delays for the anticipated GPT-5 due to integration challenges, while OpenAI prepares to launch new reasoning models shortly.
