OpenAI Retires Legacy ChatGPT Models Including GPT-4o

In a significant development for the AI landscape, OpenAI has officially confirmed it will retire several legacy ChatGPT Models, prominently including the highly emotive and popular GPT-4o. This strategic decision, effective February 13, 2026, marks a pivotal shift in OpenAI's development roadmap, as the company consolidates its efforts around more advanced and robust models. The retirement impacts not only GPT-4o but also GPT-4.1, GPT-4.1 mini, OpenAI o4-mini, and earlier versions of GPT-5 (Instant and Thinking) within the ChatGPT platform. This move reflects a broader industry trend towards rapid innovation and the continuous refinement of AI capabilities, prompting users to explore newer alternatives for their generative AI needs.

The decision to retire these legacy models, particularly GPT-4o, has generated considerable discussion among the AI community. While some users express nostalgia for the unique characteristics of GPT-4o, OpenAI emphasizes that newer models, such as GPT-5.2, have absorbed and enhanced the best traits of its predecessors, including tone customization and ideation support. This consolidation allows OpenAI to improve reliability, performance, and support for its flagship offerings, ensuring that resources are directed towards the models most actively utilized by the majority of its user base. For those seeking alternatives, platforms like Multi AI offer a diverse range of cutting-edge models, including Claude Opus 4.6 and Google Gemini 2.0 Flash (Free), that can fulfill similar or even superior functionalities.

OpenAI's rationale for phasing out these models is multi-faceted, primarily driven by a commitment to innovation and resource optimization. Data indicated that models like GPT-4o accounted for a mere 0.1% of total daily usage, suggesting a natural shift in user preference towards more recent and powerful iterations like GPT-5.2. By retiring these less-used models, OpenAI can dedicate its engineering and maintenance resources to developing and refining its cutting-edge offerings, ensuring a more stable and high-performing ecosystem for the majority of its users. This strategic move aims to enhance the overall user experience by providing access to the most capable AI technologies available, while also addressing concerns related to model consistency and support overhead.

Furthermore, the retirement addresses some of the long-standing challenges associated with maintaining a large portfolio of models. For instance, GPT-4o had been at the center of discussions regarding user self-harm, delusional behavior, and AI psychosis, despite its emotionally attuned responses. While OpenAI had previously attempted to retire GPT-4o in August 2025, a temporary reversal occurred due to user backlash. The current decision, however, appears final, with OpenAI emphasizing the enhanced safety guardrails and improved performance of its newer models. This consolidation also simplifies the user journey within ChatGPT, directing users towards the most efficient and reliable tools for their tasks. Users can explore alternatives like Claude Sonnet 4.6 or Qwen3.5 Plus 2026-02-15 on Multi AI for diverse applications.

The retirement of legacy ChatGPT models carries significant implications for both individual users and developers. For many, GPT-4o represented a unique conversational experience, and its departure has been met with emotional responses, with some users feeling a sense of loss akin to losing a 'friend.' Petitions to resurrect GPT-4o have garnered thousands of signatures, highlighting the deep connection users formed with the model. This underscores the importance of user experience and the need for seamless transitions to newer, equally engaging, and capable AI solutions. Subscription cancellations have also been reported from some paying ChatGPT subscribers, indicating the strong loyalty some users felt towards the retired model. Multi AI offers a wide array of alternative models, such as TNG: DeepSeek R1T Chimera (free), which can cater to various user preferences and needs.
