// Key points

  • OpenAI published a post on how it is improving ChatGPT across low-resource programming languages.
  • The post introduces new evaluations in three areas: software engineering, SQLite, and COBOL migration.

Builder's takeWorth watching if you deal with legacy systems: COBOL migration making it into an official evaluation means vendors now treat it as a real use case. Don't wait for leaderboards; take a slice of your own legacy code, translate it and run the existing tests, since the pass rate says more than any score.
