New Delhi: OpenAI is now all set to say goodbye to its several ChatGPT models. The models being phased out include GPT-5, GPT-4o, GPT4.1 mini, and OpenAI o4-mini. OpenAI has already shared the deprecation timeline earlier this month, confirming that these models will no longer be available in ChatGPT after the deadline. OpenAI has stated that the decision was driven by low adoption, and the majority of the users have already shifted to newer models. GPT-4o, which was briefly returned after being removed during the GPT-5 rollout, will also be discontinued as part of their plan.
This latest update will apply only to ChatGPT and does not impact the API for now. It also noted that the majority of the users have shifted to GPT-5.2 with only about 0.1% of daily users still using the GPT-4o. OpenAI has also phased out older models to help it concentrate resources on improving the versions that are more widely used. OpenAI has stated that feedback from users has been important in guiding the development of its newer models. The company said that it has enhanced conversation quality, creative assistance, and personalization features, which include controls for tone and writing style. It has also worked on reducing the responses that feel overly cautious or preachy.
OpenAI is also working on the latest version of ChatGPT, designed specifically for adult users. It is using age-estimation tools in most markets to regulate better how the younger users access and use the platform. GPT-4o has had a comparatively complex history; it was initially withdrawn during the early GPT-5 rollout but was reinstated following feedback. The model also attracted criticism over what OpenAI has also described as sycophantic behavior. The company has reversed an update to GPT-4o after the users highlighted the issue, restoring a previous version that provided more balanced responses.
