GPT-5 Understands the Pack SDK & Vibe-codes good pack code

Making Packs
1

I’ve been experimenting with GPT-5 for building Coda Packs.

Unlike GPT-4, it seems to have a good understanding of the Coda Pack SDK documentation and generates good code for the simple packs I have tested so far.

Not 100% correct - so you still need to understand Typescript, JSON, and the Pack SDK yourself to help you tease out the errors.

But once you have spotted what it has gotten wrong and explained it in your dialog, it will correct the problem very well.

So its not yet safe for total non-coders to use unacompanied - but its getting there.

Its WAY better than Replit, Claude, and previous OpenAI models. I am assuming that Coda has shared more code examples with OpenAI as part of its arrangement to use OpenAI in Coda AI?

I love this. Thanks for sharing, @Agile_Dynamics. Been asking about this for a while and was surprised at the previous LLM’s difficulty interpreting. I’ll have to give it another go now with GPT-5.

I have just tried GPT5 (using entreprise Copilot license) to vibe code my first pack (a sync table through an API). Spent 2h with GPT5 and was stuck in a long ping-pong to nail down what was wrong.
Tried Grok (free tier) and it got it right after 2 iterations…
