OpenAI has officially announced the discontinuation (shutdown) of multiple older AI models in ChatGPT, effective 13 February 2026. This is a significant platform decision that affects anyone who regularly uses ChatGPT — especially users who prefer specific models for writing, creativity, or other tasks.

Here’s what’s changing:

❌ 1. These Popular Models Will Be Retired

OpenAI plans to remove access to several legacy ChatGPT models from the ChatGPT interdata-face — meaning you won’t be able to select them anymore after the cutoff date. The models include:

• GPT‑4o
• GPT‑4.1
• GPT‑4.1 mini
• OpenAI o4‑mini
• GPT‑5 Instant
• GPT‑5 Thinking

Once February 13 hits, these will no longer appear in the model selector inside ChatGPT — though some may still be used in the background or via API for developers.

🆕 2. What Replaces These Models?

OpenAI has moved its focus to newer generations of AI, especially GPT‑5.2, which is now the main model powering ChatGPT going forward. GPT‑5.2 features improved reasoning and capabilities and is intended to deliver smarter and faster responses across tasks.

This move is part of OpenAI’s evolution strategy: remove older systems to streamline performance and push users toward the most advanced and supported model.

💡 3. Why Is OpenAI Doing This?

OpenAI says the decision is based on a few key reasons:

🔹 Most users have already adopted newer models, reducing demand for older ones.
🔹 Focus on efficiency and innovation — newer models like GPT‑5.2 are more capable and easier to maintain.
🔹 Retiring legacy models lowers complexity for development and support teams.
🔹 It lets OpenAI concentrate resources on the AI systems used by the majority.

However, users are clearly reacting strongly to the change.

🧠 4. Community Backlash Is Real

The decision has sparked a wave of disappointment and frustration online, especially among users who relied on older models. Some reasons include:

• GPT‑4o was beloved for its conversational tone and creative style, with many users preferring it over newer versions.
• Businesses and power users built workflows around these models and feel the retirement disrupts productivity.
• Some subscribers say OpenAI’s short two‑week notice period is too little time to adapt.

Whether for creative writing, companionship‑style chat, or specific job tasks, many users feel this change impacts how they use ChatGPT daily.

🧩 5. What This Means for You as a User

🎯 After February 13, 2026:

• You won’t see GPT‑4o, GPT‑4.1, or the mini models in ChatGPT’s model picker.
• ChatGPT will default to GPT‑5.2 or other newer versions.
• If you depend on a model’s specific style or behavior, you may need to adapt your workflows.
• For developers using the OpenAI API, many of these models may still be available for now, but changes could come later.

⚙️ 6. Transition Tips for Users

To adjust smoothly:

✔️ Explore GPT‑5.2 and its features now, before the older models disappear.
✔️ In workflows that depend on specific model behavior, test tasks early to avoid last‑minute surprises.
✔️ Keep track of OpenAI system updates — model availability can change quickly.
✔️ If you’re a developer relying on retired models, watch API docs closely for migration plans.

📌 Summary

OpenAI is retiring legacy ChatGPT models — including GPT‑4o, GPT‑4.1 series, and others — on 13 Feb 2026 to standardize around newer AI like GPT‑5.2. This affects how users interact with ChatGPT and reflects OpenAI’s shift toward more advanced, unified systems, even if it frustrates some in the community.
