Same, and now seven months later a GBP 20 per month Plus subscription gets me basically all the GPT-6-Luna-xhigh I can eat, which does a tremendous job of Haskell. It's even helped me with some really gnarly things like this, which require deep knowledge of the GHC RTS: https://github.com/tomjaguarpaw/bluefin/commit/c298733bdd67d...

It's possible it's much slower when working on Haskell than it is on other languages. I wouldn't know because I've only tried it on Haskell. But I'm very happy (and extremely impressed) by it.
