For context: OpenAI is playing against a professional team this time, unlike the event a few weeks ago where the humans were skilled but not active pros or used to playing together. This team isn't the strongest (they placed 17-18th during this TI) but OpenAI will play again tomorrow and the day after, presumably against progressively better teams.

Seems like playing one of the best 200 players in the world is a reasonable proxy for a top tier player. I'm unfamiliar with DOTA rules, but does anyone know if there are any limitations on the openAI team? e.g. Things like keystrokes per minute, scroll speed, etc

These were the limitations for the previous OpenAI game:

- Random Draft using a pool of 18 heroes (Crystal Maiden, Death Prophet, Earthshaker, Gyrocopter, Lich, Lion, Necrophos, Queen of Pain, Razor, Riki, Shadow Fiend, Slark, Sniper, Sven, Tidehunter, Viper, or Witch Doctor)

- No summons/illusions

- 5 invulnerable couriers, no exploiting them by scouting or tanking

- No Scan

Not sure if this match has the same limitations, but all heroes in the current game but one (Axe) are in list above, so maybe they added a few new heroes to the allowed pool.

Wait… the big news here is steam.tv. I heard the rumors but didn't know it was up?! (it seems to work only for their own event at this time tho.)

I didn't even look at the URL, I assumed this was a twitch link. Makes sense they would showcase it on their flagship game though

One thing to note is that there is a significant difference between five top-200 players and a team composed of the same, in terms of coordination and familiarity with playstyle.

This time, OpenAI is playing a normal game without restrictions. Team Human got thoroughly trashed last time vs OpenAI in a game with hero restrictions. Go OpenAI! I For One welcome our new robot overlords.

Not quite a normal game with no restrictions because it's a pre-selected hero pick from a limited pool instead of a full draft, but it's still very cool. Interesting that OpenAI seems to prefer deathballing, but it makes sense: its main advantage over humans is probably tactical and in teamfights, and 5-man maximizes your options. The human strategy should probably be to split push, but one of the commentators (who i…

I recall reading somewhere that the real advantage AI had was in it's ability to come up with bizarre strategies that confuse human opponents.

Earlier quoted context omitted.

During the last OpenAI showmatch the bots had an artificial 200ms reaction time imposed on them, I assume it's the same here but I'm not sure.

I don't believe this is the case, as OpenAI was able to hex (an immediate disable) Earthshaker before he got off Echoslam (a spell with no cast delay except the time to click the key).

The ES player didn't queue his abilities so there was delay between blinking and casting echo. Someone counted the frames and it was well over the 200ms minimum.

Did he blink in? Is there a delay there?

How can I tell looking at the screen who is winning? Is there a score somewhere? Maybe the left side sliders?

Its not always exactly obvious. But generally speaking, number of kills + towers destroyed is always a good indicator. Another good indicator is overall networth, the team winning usually has 3 out of their 5 players at the top 5 ranks in money value.

One thing you can see is which team is constantly defending and which is constantly attacking. That's a pretty good indicator too.

No guarantees though, games have been known to flop and be unpredictable, mostly due to respawn timers / buybacks lategame. Late game is super critical on who gets first kill generally
