How good are modern language models compared to humans at the task language models are trained on (next token prediction on internet text)? We found that humans seem to be consistently worse at next-token prediction (in terms of both top-1 accuracy and perplexity) than even small models like Fairseq-125M, a 12-layer transformer roughly the size and quality of GPT-1.

Artificial superintelligence (ASI) may be developed in the next few years. It is unclear whether alignment is on track to be ready on the same timeframe. At a minimum, the empirical programs at AI labs are unlikely to deliver a priori confidence, before training ASI, that things will go well. We are starting a large nonprofit research organization, Sequent, that aims to clear a higher bar:
How many years will pass before transformative AI is built? Three people who have thought about this question a lot are Ajeya Cotra from Open Philanthropy, Daniel Kokotajlo from OpenAI and Ege Erdil from Epoch. Despite each spending at least hundreds of hours investigating this question, they still still disagree substantially about the relevant timescales. For instance, here are their median timelines for one operationalization of transformative AI:
| Median Estimate for when 99% of currently fully remote jobs will be automatable | |
|---|---|
| Daniel | 4 years |
| Ajeya | 13 years |
| Ege | 40 years |
You can see the strength of their disagreements in the graphs below, where they give very different probability distributions over two questions relating to AGI development (note that these graphs are very rough and are only intended to capture high-level differences, and especially aren't very...
Blast from the past! Now that it's been a few years, some of the stages in my mini-scenario have indeed come to pass, albeit a few months later than in the scenario. I'd say we are roughly at stage 4 now:
...(1) Q1 2024: A bigger, better model than GPT-4 is released by some lab. It's multimodal; it can take a screenshot as input and output not just tokens but keystrokes and mouseclicks and images. Just like with GPT-4 vs. GPT-3.5 vs. GPT-3, it turns out to have new emergent capabilities. Everything GPT-4 can do, it can do better, but there are also some qualit
I often use what I’ll call the “safety-usefulness tradeoff model”, which is: developers face a tradeoff between "safety" and "usefulness" of an AI deployment, and the developer has only limited willingness or ability to sacrifice usefulness for the sake of safety. This model assumes that developers choose whether to take safety-relevant actions based on their cost efficiency, i.e., the marginal safety gain relative to the cost. However, that is not necessarily true. In this post, I spell out different stories for how developers choose what safety-relevant actions to take, in order to clarify when this model is relevant and how strategies for reducing AI risk are affected when its assumptions don't hold.

The model suggests two ways a safety-concerned person can increase safety:
Summary: AGI isn't super likely to come super soon. People should be working on stuff that saves humanity in worlds where AGI comes in 20 or 50 years, in addition to stuff that saves humanity in worlds where AGI comes in the next 10 years.

By "AGI" I mean the thing that has very large effects on the world (e.g., it kills everyone) via the same sort of route that humanity has large effects on the world. The route is where you figure out how to figure stuff out, and you figure a lot of stuff out using your figure-outers, and then the stuff you...
I think this is a solid partial example of what I call confrontation-worthy empathy: https://www.youtube.com/watch?v=QYVOxn-Ndxw
