ChatGPT 4o already back for Plus users

Enable via Profile → Settings → General → "Show legacy models":

then switch from the main drop-down menu:

Impressively swift handling of the "feedback and passion":

• ChatGPT users are not happy with GPT-5 launch as thousands take to Reddit claiming the new upgrade ‘is horrible’

• GPT5 is horrible

• GPT-5 is awful

• GPT-5 is a disaster.

• I always look at the bright side, but ChatGPT 5 is fundamentally and completely broken.

• Cancelled until they bring back 4o

• GPT-5 is not an upgrade. It is a forced downgrade.

• OpenAI just pulled the biggest bait-and-switch in AI history and I'm done.

• GPT5 Dissatisfaction

• GPT 5 is a complete mess!

• Please bring back GPT- 4o.

• Naw. We done.

• Removing GPT4o- biggest mistake ever!

• GPT-5 sucks. That’s all.

• HEAR ME OUT.

• WHYyy?

• After a thorough evaluation of ChatGPT 5, these are my realizations

• GPT-5 situation be like:

• Glad I’m not the only one

• no warning, broken memory, lower limits - GPT-5 “upgrade” just wrecked months of my work

• I’m sorry but I’m being reasonable - 5.0 is a disappointment and OpenAI has acted poorly

• Bring back ChatGPT-4o

• Bring back o3, o3-pro, 4.5 & 4o!

• GPT5 is clearly a cost-saving exercise

• GPT-5 hot take

• The GPT-5 Launch Was Concerning

though responses still seem closer to 5 than 4o in my limited testing, so asked 4o to weigh in:

"GPT‑4o may be running the same model weights, but OpenAI can modify its behavior through backend adjustments, meaning the version now available may not feel identical to the one users knew before the GPT‑5 rollout."
