There is nothing transparent about OpenAI. They have never released any of their models to the public, despite the fact that their models play completely different strategies to humans in an extremely heavily modified version of the game (multiple updates out of date, 80%+ of the heroes turned off, many core mechanics disabled or modified beyond recognition). Without them releasing the models for people to practice against there is absolutely no way to tell the difference between AI superiority and the humans being unfamiliar with the enemy tactics and even the very game they are playing. Compared to actual professional Dota, where pros have tens or hundreds of matches played by their opponents to study, an ecosystem of thousands of top level players hashing out new strategies for each patch and months to practice that particular version of the game, this is not a test I would call "open".
