Short answerOpenAI lists the selected model and capability settings as not carrying over. After migration check model choice, temperature (randomness), maximum answer length and tools, then retest, because each changes behavior.
What does not carry over (OpenAI plugin migration)
OpenAI's migration guide says the selected model does not transfer (workspace defaults apply) and capability settings do not guarantee the same tools or behavior. Elsewhere, expect to set these yourself.
Settings to review
| Setting | Effect |
|---|---|
| Model | Quality, speed, cost and style |
| Temperature | Lower is more consistent; higher is more varied. Support bots usually prefer lower |
| Max answer length | Cuts off or shortens replies and limits cost |
| Tools | Search, files, code, Actions: only what you enable |
How to approach it
- Note the original GPT's behavior with the test prompts.
- Set a modest temperature on the new platform if it offers the option.
- Adjust one setting at a time and compare.
