Use Grok 4.5 to build full-stack apps with Convex
Mikeysee@mikeysee· 9. Juli 2026Wow Grok 4.5 is very impressive at @convex code. Almost perfect score with a very very low run cost! Nice work @SpaceXAI!
Without the guidelines it is worse as expected so make sure you are using the guidelines file (ai-files) when using Grok 4.5 + Convex.

Impressive Intelligence vs. Cost for Grok 4.5
I think given terafab + the Tesla FSD team's expertise in making very efficient AI models, this advantage will only continue to compound
