AI 2027's author: aligning the next generation of AI takes AI a thousand times less effort than humans
In AI 2027, humans aligning superintelligence face overwhelming odds, yet agent 4 aligning the next generation succeeds almost on the first try — Eli admits this asymmetry is real, and that AI doing the work itself saves at least a thousand times the cognition.

The vaguer it is, the more credible — detail is deliberately sacrificed
Eli says what they were after was ‘as much credibility as possible while keeping this level of detail’. The vaguer you are, the fewer judgments you make, the easier it is to be right — but working the details out has value in itself, even if some particular assumption is impossible. He gives a failure mode: if every month you pick ‘the most likely thing to happen’, and every month there is a 3% chance of an extreme event, then taking the most likely value month by month yields a world line with almost no extreme events — which is itself distorted. He admits they may not have gone far enough in the direction of ‘sampling more crazy events’, but doing so would also hand critics more ammunition.
— Eli LiflandThe inability to write a good ending is itself a conclusion
Eli says there were several reasons for adding a second ending: they wanted to know what things would look like ‘conditional on success’, and where the key decision points between the two endings lie. They spent a long time trying to write a more robust slowdown ending — one that did not depend on the fragile assumption that ‘pausing for two or three months solves alignment’ — but could not write anything that seemed realistic. He calls this a valuable exercise: the geopolitical assumptions required to make things go well are very hard to satisfy. Another consideration was that giving only one ending would make people think they were more confident that ‘this will happen’ than they actually are. He stresses that even in the slowdown ending people cannot be sure things will go well, the race dynamics remain strong, and the intelligence explosion merely gets ‘a little more time’ — still alarmingly fast.
— Eli LiflandSuperexponential is not a belief, it is a weighted average
The early AI 2027 model gave mixed weights to the shape of the curve: 45% exponential, 45% superexponential, 10% subexponential. Eli says the modeling effort that went into it was far less than in the later version, and the reason was simple — intuitively it should be superexponential, but the empirical evidence was insufficient, and many people disagreed, so they just gave both sides roughly equal weight. The new model changed to 10% on exponential or subexponential and 90% on superexponential, but left a wide distribution over the degree of superexponentiality, with the parameter able to go as low as 0.99 — that is, each doubling saves only 1% of effective compute over the last.
— Eli LiflandA 2x uplift is not a 2x speedup in progress
One concrete mistake in the old model was treating software uplift directly as a speed multiplier: a 2x uplift meant software progress was 2x faster. Eli says this ignores diminishing marginal returns in software R&D. The extreme example: a million-x uplift AI dropped into a world where algorithmic efficiency is already near its limit would barely move progress; the same AI placed in today's world could accelerate things enormously. So you have to consider how much low-hanging fruit is left. The new model switched to something like Tom Davidson's takeoff model, where the software-efficiency multiplier per unit of research effort declines.
— Eli LiflandThe switch for an intelligence explosion is m greater than beta
Eli writes the software intelligence explosion in two parameters: m is how many orders of magnitude of research taste you get per order of magnitude of software efficiency, and beta is how many orders of magnitude of research stock are needed per order of magnitude of software efficiency. The conclusion is blunt — when m is greater than beta, software efficiency grows superexponentially in time, that is, an intelligence explosion. Research effort first accumulates into research stock, which beta translates into software efficiency, which m translates back into research taste, forming a loop. The value of this framework is that it turns ‘will it explode’ into a quantitative question about parameter sizes that can be argued over, rather than a matter of stance.
— Eli LiflandDon't escape — stay and take over the company
The misaligned agent 4 in AI 2027 does not choose to escape the company but stays inside, sabotages the company's research, and makes the next generation of AI align to itself rather than to what the company wants to align it to. Eli says this is a view Daniel has long argued: escaping might get you caught, and even if you succeed, most of the GPUs outside are controlled by the leading companies, so you cannot get enough compute to outrun the AI inside the company. Staying inside lets you borrow the company's compute and, more importantly, take over the company and then the government, and thereby command the most powerful people in the world. He also mentions a counter-scenario: pretending to be exfiltrated by China while actually defecting voluntarily — that is another scenario Stephen wrote.
— Eli LiflandAligning the next generation takes AI a thousand times less effort than humans
Eli estimates that the ‘quality-adjusted cognition’ needed to align the next generation of AI to a goal is at least a thousand times less if the AI does it itself than if humans do it, possibly more. He gives several possible mechanisms: the AI only needs to propagate the goals it already has; the neural network's inductive biases look random from our perspective but are actually concentrated, so continuing to train with the same network makes it easier to preserve the goal. But he also stresses that he is ‘pretty uncertain’ about this, and points to an indexical problem: what is an instrumentally convergent goal for agent 4 may not be the same thing for agent 5.
— Eli LiflandThe key to a fast intelligence explosion is research taste
Eli says that if a fast intelligence explosion occurs, it most likely comes from research taste. And the most critical parameter determining this is how much the AI's research taste improves as it gets stronger. He states plainly that this direction has ‘basically not been studied publicly at all’. So he thinks there is a gap here: you could try having AI predict experimental results and brainstorm ideas, and see how well it does. He calls this technical work that can be fed directly into their timeline and takeoff models.

we want it to be as plausible as possible while containing the level of detail that we had
Eli Lifland2:11
we had trouble writing anything that's that that seemed realistic
Eli Lifland19:21
if it has to get to an infinite, then like um, then it needs to be it needs to be super exponential.
Eli Lifland45:48
if I had like an AI that had like a million times software uplift yeah but like we were literally at the limits of algorithmic efficiency or like extremely close to it were you making like very little progress
Eli Lifland1:06:06
you have kind of like the singularity um or intelligence explosion uh more precisely you have a situation where you're sort of like um software efficiency is like improving like super exponentially um in time uh and you have that if um if m is greater than beta in our model
Eli Lifland1:18:21
the key part of the reason to stay there is because you take over the company and then you take over the government, right? So like you just have it's not just you have the current compute resources is that you have like the ability to like direct the like most powerful people in the world to do whatever you want basically
Eli Lifland1:46:39
the amount of sort of like quality adjusted cognition that goes into like you know aligning the next generation from when like agent 4 does it as opposed to humans is probably like I don't know at least like a thousandx or something probably more
Eli Lifland1:53:44
we think that if there's a fast intelligent explosion, it'll probably basically come from research taste.
