GPT 5.2 in "Flex" mode

I actually have a question if someone is able to answer me at some point. I’m hoping to run my AI Agent in this workflow <https://gogipper.app.n8n.cloud/workflow/XyOul7ksAzGlSeOm> with GPT 5.2 in “Flex” mode (its a means of cost saving). In the language node, it seems like its possible - see screenshot, but I wasn’t seeing everything coming over when it ran. Any ideas here? Is there a way I can get this working? Any feedback would be super appreciated.[image: Screenshot 2025-12-25 at 8.20.58 PM.png]

What image were you trying to share @Manav_Parasiya

Hi @Baseman, this question was originally raised by Jack in an n8n GitHub issue (https://github.com/n8n-io/n8n/issues/23101#issuecomment-3691889456). I’ve shared the same question here in the community so he can get an answer here.

Hopefully, he’ll see this topic and share the image here.
