Custom GPT Issue: 5.1 model inaccessible when using Custom Actions

Since the release of 5-Instant, our CustomGPT can no longer access the 5.1 model which the Custom GPT was built and tested on.

Unfortunately, this is to be expected, as we’re using a custom action within the GPT (see below)

Wondering if there are plans to make custom actions work in 5.1 again? The 5-Instant model materially changes the behavior of the Custom GPT and negatively impacts the user experience. Any useful info would be appreciated. Thanks

All I can say is I have the same question. Really downgraded the quality of our agent. Hoping they allow 5.1 or 5.2 to use actions.

Here to ask this same question. Is this something where there will be a path to using other models in the future? Or is this a lock in to an older model because GPTs are being deprecated, motivating folks to come up with another solution?

And just like that, now my custom GPT can use 5.2 Amazing coincidence if they just changed this today since I made this post.
