Superhuman coder 5x, superhuman AI researcher 25x, superintelligence 1000x
The takeoff forecast was made by breaking down how the intelligence explosion would go into a series of milestones. First you automate the coding, then you automate the whole research process, but in a very similar way to how humans do it with teams of agents that are about human level, then you get to superhuman level and so forth.
The milestones were broken down into the superhuman coder, superhuman AI researcher, and then super intelligent AI researcher. For each of these milestones, they asked what it is going to take to make an AI that achieves that milestone, how much is the overall speedup once you achieve that milestone, and what it is going to take to achieve the next milestone, then combined that with the overall speedup to get the clock time distance until that happens.
Quantitatively they were thinking something like a 5x speedup to algorithmic progress from the superhuman coder. The 5x is for the algorithmic progress part, not for the overall thing, where the algorithms would be advancing at 5x speed, but the compute is still stuck at the usual speed, so basically things would be going 2.5x faster. He said he is not very confident in that 5x number, it could be lower, it could be higher.
The superhuman AI researcher was something like a 25x speedup to algorithmic progress, because at that point you have got the whole stack automated, which he thinks is substantially more useful than just automating the coding. He said he forgets what they say for a super intelligent AI researcher, but off the top of his head it is probably something in the hundreds or maybe like 1000x overall speed up.
