ChatGPT将停用GPT-4o、GPT-4.1等模型

OpenAI has announced the retirement of several existing models from ChatGPT, effective February 13, 2026. This discontinuation includes GPT-4o, GPT-4.1, GPT-4.1 mini, and OpenAI o4-mini, aligning with the previously announced retirement of the GPT-5 series models (Instant, Thinking, and Pro). Consequently, ChatGPT users will no longer be able to access or utilize these specific model versions directly through the platform after the specified date. This retirement initiative aims to streamline the model ecosystem, potentially paving the way for the introduction of more advanced and higher-performing next-generation models. For users relying on these models for daily tasks or specific applications, this change will necessitate adaptation or migration to other available models. Crucially, OpenAI explicitly states that this model retirement is confined to the ChatGPT platform and currently has no impact on API services. This implies that developers and enterprise users leveraging these models via API calls can continue their usage without immediate code or system adjustments. This distinction suggests OpenAI is employing different strategies for its platform users versus its developer ecosystem, potentially acknowledging the higher demands for model stability and compatibility among API users. Future changes at the API level will require close monitoring of official OpenAI announcements. This retirement represents a standard step in OpenAI's model iteration and upgrade cycle, designed to continually enhance the overall quality and user experience of its AI services. Users and developers are advised to closely follow OpenAI's subsequent updates to adjust their AI application strategies accordingly.
