Confidence: High, Funding needs: Medium

This is an excellent thing to focus on, and one of the places we are most likely to be able to show ‘fire alarms’ that make people sit up and notice. Their first year seems to have gone well, one example would be their presentation at the UK safety summit that LLMs can strategically deceive their primary users when put under pressure. They will need serious funding to fully do the job in front of them, hopefully like METR they can be helped by the task being highly legible.

They suggest looking at this paper, and also this one. I can verify that they are the real deal and doing the work.

Apollo Research: Scale up interpretability & behavioral model evals research, Aug 2023

**Main points in favor of this grant**

I am quite excited about deception evaluations (https://www.lesswrong.com/posts/Km9sHjHTsBdbgwKyi/monitoring-for-deceptive-alignment), transparency and interpretability (https://www.lesswrong.com/posts/nbq2bWLcYmSGup9aF/a-transparency-and-interpretability-tech-tree), and especially the combination of the two (https://www.lesswrong.com/posts/uqAdqrvxqGqeBHjTP/towards-understanding-based-safety-evaluations). If I were crafting my ideal agenda for a new alignment org, it would be pretty close to what Apollo has settled on. Additionally, I mentored Marius, who's one of the co-founders, and I have confidence that he understands what needs to be done for the agenda they're tackling and has the competence to give it a real attempt. I've also met Lee and feel similarly about him.

**Donor's main reservations**

My main reservations are:

  • It's plausible that Apollo is scaling too quickly. I don't know exactly how many people they've hired so far or plan to hire, but I do think that they should be careful not to overextend themselves and expand too rapidly. I do want Apollo to be well-funded, but I am somewhat wary of that resulting in them expanding their headcount too quickly.
  • As Apollo is a small lab, it might be quite difficult for them to get access to state-of-the-art models, which I think would be likely to slow down their agenda substantially. I'd be worried especially if Apollo was trading off against people going to work directly on safety at large labs (OAI, Anthropic, GDM) where large model access is more available. Though this would also be mitigated substantially if Apollo was able to find a way to work with labs to get approval to use their models for research purposes externally, and I do not know if that will happen or not.

**Process for deciding amount**

I decided on my $100k amount in conjunction with Tristan Hume, so that we would be together granting $300k. Both of us were excited about Apollo, but Tristan was more relatively excited about Apollo compared to other grants, so he decided to go in for the larger amount. I think $300k is a reasonable amount for Apollo to be able to spin up initial operations, ideally in conjunction with support from other funders as well.

**Conflicts of interest**

Marius was a mentee of mine in the SERI MATS program.

I'm very excited about Apollo based on a combination of the track record of it's founding employees and the research agenda they've articulated.

Marius) and Lee) have published work that's significantly contributed to Anthropic's work on dictionary learning). I've also met both Marius and Lee and have confidence in them to do a good job with Apollo.

Additionally, I'm very much a fan of alignment and dangerous capability evals as an area of research and think there's lots of room for more people to work on them.

In terms of cost-effectiveness I like these research areas because they're ones I think are very tractable to approach from outside a major lab in a helpful way, while not taking large amounts of compute. I also think Apollo existing in London will allow them to hire underutilized talent that would have trouble getting a U.S. visa.

I think Apollo is going to be very hard to beat for a few reasons and I would have written up the grant if Marius didn't.

  • They are a very very talented team. I think several people involved could be working at top AI labs.
  • They are focused on a tractable and "most important problem" of deception in AI systems.
  • They seem well positioned to be a potential centre for an AI safety org in Europe
  • They could grow to absorb a lot more funding, effectively. A key barrier to EA funds right now is productively spending lots of money. Seems possible that they could absorb >20M/year in 4 years time
  • I think the people here are very "alignment-pilled"
  • I think I am a good judge of talent/character and Marius passes the bar.
  • I have a preference that they become a non-profit vs for-profit company that sells auditing and red-teaming. I think funding in the first few years will be pivotal for this.

Reservation:

  • They seem quite expensive on a per person basis compared to other projects Manifund has been funding. That said, there is going to be a lot of "bang per person here". Marius explained to me that they are competing with large AI labs and are already a significant salary cut. I would much rather see someone working within Apollo than doing independent research. I think we should be quite weary of funding independent researchers until orgs like Apollo are fully funded, with rare exceptions.
  • I still don't get why SFF and OP can't just fully fund them. My best guess here is that they are terrified of seeding another "AI accelerator" or wanting to save their cash for other things and thus allow others to donate in their place.
  • I am slightly worried that there isn't a good way to coordinate across the community of "how much they should receive". From the inside, Apollo wants to raise as much as possible. I don't think that is optimal at a movement level and this leads to them spending a lot of time fundraising so they can have more money. There probably is a funding level that Apollo shouldn't exceed in it's first year though I don't know what that number is.

I would bet that if we reviewed Apollo 1.5-2 years down the line, it will outperform a majority of grants on a per dollar basis (very hard to operationalize this though).
