Summary

Over a two-day workshop, Metaculus Pro Forecasters and subject-matter experts (SMEs) from several organizations evaluated policy directions for reducing AI risk using scenario planning and forecasting methodologies. The key conclusions:

Pro Forecasters and SMEs are most optimistic about risk reduction stemming from API restrictions and AI model export controls—specifically, API restrictions aimed at preventing calls that could induce recursive self-improvement.
- Model export controls may hamstring open source efforts to build and proliferate powerful AI.
There’s only a low likelihood of meaningful U.S. policy action on AI before 2027, though this likelihood increases if an AI incident occurs in the meantime.
- By “meaningful policy action”, we mean policy action that non-trivially reduces existential risk. Hardware restrictions, firmware requirements, API regulation, and licenses for large data center clusters, among other potential policy actions, were evaluated in the workshop.
As transformative AI is approached, the players will likely be a small number of for-profit AI labs, though this isn’t a guarantee.
The forecasts indicate moderate pessimism about the likelihood of leading AI labs coordinating with each other to slow the AI capabilities race, and pessimism about the likelihood of an international AI treaty involving the U.S. and China.

Introduction

The increasing capabilities of artificial intelligence have led to a growing sense of urgency to consider the potential risks and possibilities associated with these powerful systems, which are now garnering attention from public and political spheres. Notably, the Future of Life Institute’s open letter calling for a six month pause on leading AI development collected over 25,000 signatures within five weeks of release, and senior White House officials have met with AI leaders to discuss risks from AI.

This report presents the findings of a structured process, organized by Metaculus and the Future of Life Institute, which brought together Pro Forecasters and SMEs to begin identifying, quantitatively, the most impactful policy directions for reducing existential risk from misaligned AI (hereafter: “AI risk”).

Methods

The AI Pathways workshop combined a range of plausible scenarios for an AI future with probabilistic forecasts, leveraging the judgments of both SMEs and Metaculus Pro Forecasters. The goal of the exercise was to identify the most impactful actions for steering toward a positive future and away from a negative future.

We—the Metaculus AI Forecasting team, in collaboration with the FLI policy team—began by generating four possible states of the world in 2030, focusing on the impact of AI, and asking experts to identify developments which would likely play a large role in driving the world toward each of these four scenarios. The scenarios were developed with two key areas of uncertainty in mind: 1) takeoff speed and the related question of unipolarity versus multipolarity; 2) cooperation versus competition—between labs and between countries. The “Scenarios” section below outlines these scenarios in more depth. We worked with the SMEs to identify “indicators” or “drivers” of these scenarios, ranked these, identified potential U.S. government policies and leading lab coordination actions that could pertain to the most important twenty or so indicators, and developed corresponding forecasting questions.

Workshop teams, made up of integrated groups of technical AI experts, AI policy experts, and at least one Pro Forecaster, then forecasted on these questions. In practice, most of the forecasting questions asked about either:

The odds of a policy or coordination response (e.g., compute restrictions), conditional on whether or not an intermediate development (e.g., a warning shot) occurs.
The odds of a more terminal development (e.g., recursive self-improvement), conditional on whether or not a policy or coordination action had been implemented.

All probabilities quoted in this report are the median forecast from the workshop and include forecasts from Pro Forecasters and SMEs. There were around 20 workshop participants, and the forecasting questions in this report were forecasted on by 5 or 6 participants on average. Quoted forecasts should be taken as having low to moderate resilience, and not as being fully authoritative.

Findings

Policy interventions
State of AI
1. The first transformative AI (TAI) will be developed by a for-profit company: 70% chance.
  1. The following definition of TAI was used: AI that precipitates a transition comparable to, or more significant than, the agricultural or industrial revolution.
  2. The remaining 30% was spread fairly equally over these possibilities: non-profit company, government project, nationalized company. The first TAI coming from academia or an open-source collective was judged as unlikely.
    1. A related workshop forecast: 45% chance that the open source ecosystem will have produced a GPT-4 equivalent by 2027.
2. The number of actors at the TAI forefront will likely be small, though participants don’t expect only one forefront actor. The median estimate for the number of forefront actors was 4, and the lower and upper quartiles were 2 and 7, respectively.^[2]
3. 40% chance that AI will be meaningfully discussed by both major candidates in the 2024 U.S. Presidential debate.
State of AI lab coordination
1. Participants were somewhat pessimistic about leading AI labs coordinating with each other to slow the capabilities race.
  1. “Will three of the largest AI labs issue a joint statement committing to constrain capabilities development or deployment before 2027?” received a median forecast of 50%.
  2. Key figures seem unlikely to publicly adopt a stance against AI racing, by 2025. The median forecast was around 25% for Sam Altman and for Demis Hassibis, and around 10% for each of Eric Schmidt, Jeff Dean and Yan LeCun.
Risks from AI
1. The median forecast on the chance of AI-caused global catastrophe, meaning >10% of the global population being killed, by 2030 was 2%.
2. Meanwhile, the median forecast regarding a moderate AI catastrophe by 2030 was 80%.^[3]
3. Interestingly, the chance of U.S. compute restrictions—restricting the amount of compute that is allowed to be used in training runs is one of the most commonly talked about policy interventions in AI safety—by 2025 was forecasted as substantially higher, namely, 30% versus 10%, if a moderate AI catastrophe occurs before then. The reasoning that came up repeatedly here is the idea that a warning shot, such as a moderate AI catastrophe, could act as a galvanizing event that causes proposed policies, which may currently be outside the Overton window, to gain support and be implemented. In fact, the notion that a warning shot might significantly raise the chance of policy action was a recurring theme in the workshop as a whole.

Scenarios

We—Metaculus and FLI—began this project by constructing and discussing a set of four scenarios set in 2030:

In “The Pause Perdures”:^[4]
1. Despite general stability, and ability to do so, there are no AI systems significantly more capable than GPT-4 (i.e. maybe GPT-5 level. No PASTA, no superintelligence).
2. AI is broadly integrated into society and used for many things. It has been a big adjustment.
3. Both expert consensus and some minor AI-related disasters have created a compelling case that AGI/superintelligence is a bad idea in the foreseeable future.
4. The limit on AI has been chosen by society and is enforced by human norms, laws, and institutions.
In “Gatekeeper”:
1. There is a single arguably superintelligent AI system, which is substantially more competent than all others.
2. It is owned/controlled by a multinational NGO with shared global governance.
3. It generates both scientific research and software products for the global public good (including help in governing less powerful AI systems).
4. It supports a multilateral global agreement (an international IAEA-like agency) that prevents rival superintelligences from being developed.
5. GPT-5 level systems are used broadly for many things, but are strictly capability-capped and carefully managed.
In “Accelerando, Diminuendo”:
1. There are many powerful and economically useful AI systems by 2025, and a few that could be called general intelligences by 2027. All of these are developed by major competing AI companies, and remain associated with them (though at some point the tail starts to wag the dog).
2. Between 2025 and 2026 people broadly benefit greatly from AI, and AI systems seem to be coming up with methods of collaborating amongst themselves and with human institutions.
3. From 2026 to 2027, decisions are increasingly delegated to AI systems, and there is a general feeling that nobody knows exactly what they are doing and why. Still, productivity is high, there is an endless stream of entertainment, and new technologies are appearing at a rapid rate.
4. Around 2028, things start to get markedly worse worldwide for humans, but few if any humans really understand what is going wrong—or even that things might be going wrong at all.
5. In 2030, the human population is trending sharply downward, though this is not widely known.
In “Crash on Takeoff”:
1. Timelines have been quite short, with the Metaculus (harder) AGI question resolving positive in 2026 after an AGI was developed in a massive year-long training run. This AGI is kept quite controlled, however, by its highly cautious developers.
2. In 2028, a company in secret uses a somewhat less powerful but less constrained system to do human-assisted recursive self-improvement.
3. In 2029, the humans fall out of the loop. There is brief conflict with the existing AGI, then intelligence explosion and classic instrumental drives/power-seeking behavior.
4. Humanity is extinct by 2030.

Updates

We currently plan on running subsequent AI Pathways workshops, the next being in June, as part of the overall AI Pathways project.

Feedback

The AI Pathways project represents a new, as far as we’re aware, angle of attack for anticipating the future of AI risk and judging the impact of high-stakes policy decisions. We think that some meaningful progress was made in this first workshop, and we hope that future workshops will be even more directly useful for policy decisions. We would welcome your thoughts on the utility of this project. Please direct any feedback to will@metaculus.com.

^{^}
51% vs 68% that there’ll be more than 10 actors at the forefront in 2030. Number of forefront actors is certainly not the only noteworthy effect of hardware policies, but it’s what we chose to focus on in this workshop.
^{^}
We count an actor as being at the TAI forefront if they carried out a training run within one order of magnitude of the training compute used in the run that produced the TAI.
^{^}
We define moderate catastrophe as a disaster (or series of disasters occurring within a 30-day span) that trigger a public statement of concern from at least one head of state, cabinet member, foreign minister, national security advisor, or secretary of state from one of the P5.

The main text outlines the scenario in broad strokes. Below, one concrete story for the scenario is given. (We thank the experts and forecasters in the Pause Perdures group for constructing this story.)
GPT-5 is developed by OpenAI in mid-2025.
In 2026, a terrorist cell deliberately misuses a GPT-5 level LLM to create an auto-blackmail system. It uses spear phishing campaigns to hack email, CCTV cameras, etc. to discover a wide variety of legitimate blackmail against politicians across the US, UK, China, South Korea, and Japan. Some of the blackmail material is also fabricated via deepfake audio and video, and it’s nearly impossible to tell the difference between the real and fake material. A lot of the blackmail materials are revealed amid a lot of resigning politicians, including several notable suicides and one assassination arising from the revealed blackmail information.
This AI campaign is eventually discovered by an Interpol taskforce and gets wall-to-wall coverage in every major news outlet. This coverage galvanizes international coordination towards a pause.
Throughout this story, China is at least five years behind LLM SOTA due to increasingly strong and increasingly well coordinated export controls. China’s access to cloud compute has also been heavily restricted. At the time of the pause, China has not even trained an LLM as good as GPT-4 despite significant investment.
Generally speaking, AI capabilities have remained very capital intensive, so the set of actors has remained small. At the time of the pause, only (1) OpenAI + Microsoft, (2) Google + Deepmind, (3) Anthropic, and (4) the US government are capable of making GPT >=5. Leading AI labs continue to be private and domiciled in democracies.
The US starts leading the world towards an international treaty banning AI training runs that use over ~1E28 FLOP. China initially resists these measures, but turns around and complies on account of the carrot offered: its access to AI compute supply chains are tied to participating in the treaty. (Note: an alternative story with a similar outcome could involve some successful "boxing" of China, instead of a treaty.) Secure chip technologies are developed such that centralized tracking of chips, knowledge of how they are being used, and remote shutdown are all possible. Installation of these features is mandated through supply chain controls from the U.S. government, with support from Japan, South Korea, and the Netherlands. The US government also invests heavily in cybersecurity for these actors to prevent exfiltration, and engages in a lot of compute governance.
