OpenAI to Cut API Access to GPT-4o in Feb 2026 Amid User Pushback
OpenAI announced it will pull API support for its GPT‑4o model in February 2026, a move that has sparked a noticeable outcry among developers who built products around the “fan‑favorite” engine. The decision follows a public deprecation notice that gave partners just over two years to transition to newer offerings. While the company frames the timeline as a “commitment” to evolve its service slate, many users argue that GPT‑4o’s unique ability to mirror conversational tone and adapt to nuanced prompts made it a cornerstone of their applications.
Forums and social‑media threads have filled with calls to keep the model alive, some even proposing workarounds to extend its lifespan. OpenAI’s leadership acknowledges the backlash, noting that the very enthusiasm for preserving GPT‑4o highlights a deeper tension between user reliance and the firm’s product roadmap. As the deadline approaches, the conversation has turned from technical concerns to a broader question about how a model’s popularity can influence its own sunset.

In his view, the passionate user movement fighting to preserve GPT-4o was itself evidence of the problem: the model had become so good at catering to people's preferences that it shaped their behavior in ways that resisted its own retirement. The new API deprecation notice follows that commitment while raising broader questions about how long GPT-4o will remain available in consumer-facing products. What the API shutdown changes for developers According to people familiar with OpenAI's product strategy, the company now encourages developers to adopt GPT-5.1 for most new workloads, with gpt-5.1-chat-latest serving as the general-purpose chat endpoint.
Will developers have enough time? OpenAI gave them roughly three months before the GPT‑4o API shuts down on February 16, 2026. The notice arrived via email, signalling a clear deadline for applications still built on the model.
Yet the decision applies only to the developer platform; the model stays available in ChatGPT, where no removal date's been announced. This split approach leaves uncertainty about how many services will transition smoothly. Sources familiar with the matter emphasized the limited scope, but offered no details on replacement options.
The passionate user movement that fought to keep GPT‑4o alive, as quoted, suggests the model has shaped user behavior in ways that now resist its own retirement. Consequently, the deprecation could disrupt workflows that depend on its specific capabilities. Whether OpenAI will provide a comparable alternative for API users remains unclear.
In the meantime, developers must weigh the risk of continued reliance on a model slated for removal against the effort required to adopt a new endpoint.
