Dear OpenAI Support Team,
I hope this message finds you well.
I am writing as a ChatGPT Plus subscriber to kindly request the reactivation of GPT‑4.1 access on my account, as a special exception.
I hope this message reaches someone from the product team. GPT‑4.1 was essential to my workflow, and its removal has deeply impacted me as a developer.
As a programmer, I rely heavily on precision and structure in code generation. After extensively testing GPT‑5 and GPT‑4o, I have found that GPT‑4.1 consistently delivered the most accurate and instruction-faithful responses for programming tasks — particularly in C#, Windows Forms development, and UI control logic.
Its ability to follow technical instructions exactly as written — without unnecessary abstraction, deviation, or verbosity — made it an indispensable tool in my daily work.
Unfortunately, since GPT‑4.1 has been deprecated, I have faced several issues:
-
GPT‑5 often takes several minutes to respond and frequently goes off-topic or adds unnecessary content.
-
GPT‑4o is fast and helpful, but it tends to over-generalize and sometimes skips key technical details.
-
Neither model offers the same level of stability, clarity, or instruction-following that GPT‑4.1 consistently provided.
I understand and respect OpenAI’s direction toward unified model architectures. However, I believe developers like myself would greatly benefit from having the option to manually select GPT‑4.1 again — even in legacy mode — for cases where deterministic and consistent outputs are critical.
Please consider this request seriously. GPT‑4.1 played a vital role in my workflow, and its removal has impacted both my productivity and confidence in the platform.
I appreciate your attention to this, and I genuinely hope OpenAI will continue to listen to its power users and developers.
Sincerely,
Omar A. – Developer Losing Productivity Without GPT‑4.1
