For me, AI code generation for F# has been pretty good! There's one annoying thing Opus/Sonnet do (honestly don't remember what other models do): use old syntax for array indexing.
values.[index] // Old way of indexing required a .
values[index] // Supported for awhile now
That's the "biggest" issue I run in to, and it's not that big of a deal to me.
