This question is identical to the mid-2020 maximum compute question, except for the dates.

This question tracks increases in compute as measured by this OpenAI blog post, which delinates a methodology for estimating training compute.

By July 1st 2019, what is the maximum number of computations used by an AI system described in a published paper, pre-print or blog post, calculated using the OpenAI methodology and measured in petaflop/s-days?


A “published AI system” is a system that is the topic of a published research paper or blogpost. In order to be admissible, the paper/blog post must give sufficient information to estimate training compute, within some error threshold.

Note that the system need not be deployed for research purposes. Resolution criteria also include, for example, a blog post by a major tech company revealing the amount of training used for an image classifier used in their product.

In order to think about this question, helpful resources include this spreadsheet extrapolating the current AI compute trend along the lines suggested by Ryan Carey, and this Guesstimate model. I especially recommend checking out the calculators (by pressing the little calculator symbol in the menu bar), which allow you to enter a target compute/cost and find out how long until it's reached.

Current points depend on your prediction, the community's prediction, and the result. Your total earned points are averaged over the lifetime of the question, so predict early to get as many points as possible! See the FAQ.

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!
