Thread on @AnthropicAI's cool new paper on how large models are both predictable (scaling laws) and surprising (capability jumps).
1. That there’s a capability jump in 3-digit addition for GPT3 (left) is unsurprising. Good challenge to better predict when such jump will occur.

2. The MMLU capability jump (center) is very different b/c it’s many diverse knowledge questions with no simple algorithm like addition.
This jump is surprising and I’d like to understand better why it happens at all.
3. Program Synthesis jump (right) feels like it should be in between 1 and 2. Less diversity than 2 and we can also imagine models grokking certain concepts in programming leading to a jump.
I’d love to see more work on this topic of predictability and surprise and how they relate to forecasting alignment/risk.

The entire discussion around Facebook’s disclosures of what happened in 2016 is very frustrating. No exec stopped any investigations, but there were a lot of heated discussions about what to publish and when.


In the spring and summer of 2016, as reported by the Times, activity we traced to GRU was reported to the FBI. This was the standard model of interaction companies used for nation-state attacks against likely US targeted.

In the Spring of 2017, after a deep dive into the Fake News phenomena, the security team wanted to publish an update that covered what we had learned. At this point, we didn’t have any advertising content or the big IRA cluster, but we did know about the GRU model.

This report when through dozens of edits as different equities were represented. I did not have any meetings with Sheryl on the paper, but I can’t speak to whether she was in the loop with my higher-ups.

In the end, the difficult question of attribution was settled by us pointing to the DNI report instead of saying Russia or GRU directly. In my pre-briefs with members of Congress, I made it clear that we believed this action was GRU.
