The Offlaner's job this phase
  • Your goal isn't perfect farm — it's making sure THEIR carry doesn't farm. Contest every last hit.
  • Secure range creeps with a spell if needed; XP matters more than gold for you.
  • If the 1v2 is rough, hug your tower and ask the soft support to help zone.

Why this way? How OpenAI Five learned

  1. One hero, one role first

    OpenAI's first bot played only Shadow Fiend, only mid, until it mastered it. Stay on Tidehunter in one role before moving on.

  2. Small, measurable rewards

    OpenAI Five was rewarded for last hits and staying alive long before it understood winning. That's why each journey stage has one number to hit.

  3. From yourself to the team

    Its 'team spirit' rose over the game: early on, look after yourself; late, play for the team. Each phase's meter shows the split.

  4. Use proven builds

    OpenAI Five's builds were hand-written, not trial and error. Start from the pro build, then experiment.
