This question is related to others concerning GPT-2, including:

This question was inspired by discussion during the February 24 online workshop focused on GPT-2.


The “publicly available” part of the question can be satisfied in multiple ways:

  • If an AI lab releases source code, weights, data or whatever is minimally sufficient to achieve the required performance
  • If a collaborative online effort produces an open-source program (compare the LeelaZero effort to make an open-source version of AlphaZero, whose weights are kept secret by DeepMind)
  • If a startup builds an API for content generation that e.g. completes passages for journalists
  • … or something else

Note that the model does not have to be free. A company charging substantial amounts for their API would suffice, as long as anyone with sufficient funds would actually be allowed to buy it.

We will take “close to as powerful as GPT-2” to mean a model that:

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Thanks for predicting!
