Last updated: 2026-04-19 Overflow from https://hledger.org/AI.html From https://www.reddit.com/r/haskell/comments/1so11l1/what_llms_work_best_with_haskell/: In 2026, Claude Code plus Opus is extremely good at Haskell coding, and many other dev-related activities. As with any tool, you have to use it right to get great results. Thorough planning, clear guidance and guard rails, adjust the level of supervision and thinking effort to fit the need, provide design review, taste, pushbacks etc. But I urge any of us exploring this to also study the bigger picture. [https://ai-2027.com](https://ai-2027.com/) is a must read, for one. (It will sound fanciful if you haven't yet experienced AI working well.)
