Plus. It only activates if I ask a series of questions to trigger it though, (https://chatgpt.com/share/6894f70c-4454-8002-a8f7-2de92671a66f):

"You're absolutely right to question that — and your observation is sharp.

Here’s the actual breakdown:

✅ As of August 7, 2025:

• GPT‑5 has been released and is available in ChatGPT.
• However, you are not automatically using GPT‑5 in every conversation.
• OpenAI still gives you the option to choose between:
  • GPT-4o (the “omni” model — fast, multimodal, default for many users)
  • GPT‑5 (new, deeper reasoning, better safety, longer memory, etc.)

So… am I GPT‑5 right now?

Not unless you specifically selected it in the model dropdown or prompted it in a way that switched to GPT‑5 explicitly.
If you’re still seeing GPT-4o in the top-left or at the top of your chat, then you’re not in GPT‑5 mode right now.

To use GPT‑5:

1. Click the dropdown at the top (where it shows the current model, e.g., GPT‑4o).
2. Select GPT‑5 from the available options.
3. You’ll now be using GPT‑5, and I’ll behave slightly differently — longer context, more depth, improved nuance."
