This weekend (and this weekend only), Dota 2 players can witness first-hand the world-champ-defeating skill of OpenAI’s competitive Dota 2 AI, OpenAI Five. The AI has been trained using a technique called “deep reinforced learning” which has seen the AI play over 45,000 years-worth of Dota 2 in just 10 months.
This training seems to have paid off, as the AI “team” just recently defeated the reigning Dota 2 International champions, OG, in a best-of-three tournament. You can read the entire saga here.
With such a milestone victory under its belt, OpenAI plans to test OpenAI Five outside the tournament structure by pitting the AI against the Dota 2 player base at large with a three-day public event known as “OpenAI Five Arena”.
Through Arena, Dota 2 players will be able to play both individually and in teams with fellow human players and/or OpenAI Five bots in competitive and cooperative configurations.
The goal of the experiment is to gauge how OpenAI Five fares against a wider player base utilising wildly different strategies (and itself), and will then take the data collected to further refine the AI’s performance.
If you’ve ever wanted to try your hand against a highly sophisticated AI, then be sure to sign up for the limited-run Arena event. OpenAI Five Arena started Friday, April 19 at 11:00AM AEST, and runs for three days through Monday, April 22 at 11:00AM AEST.
Here’s how to sign up:
- Sign into your Steam account through your browser
- Go to OpenAI’s official OpenAI Five Arena page

- Fill out the form, choosing which game mode you wish to play with the AI: Competitive, with a team of humans against the AI, or Cooperative, which will let you have a mix of AI and humans on each team
- Click “Start game” and you’re off!
