About Epoch AI

Epoch AI is a multidisciplinary research institute investigating the trajectory of Artificial Intelligence (AI). We produce papers and reports on the drivers, trajectory and consequences of the development and deployment of AI.

In the past, we have produced cutting-edge AI forecasting work such as Compute Trends Across Three Eras of Machine Learning (Sevilla et al., 2022), Revisiting Algorithmic Progress (Besiroglu and Erdil, 2022) and Will We Run Out of ML Data? Evidence From Projecting Dataset Size Trends (Villalobos et al., 2022). We also maintain a database of notable ML models, widely regarded as the most comprehensive public database of its kind in existence.


Epoch does the most thoughtful and best-researched survey work in the industry. Several times I have thought I found errors in their results, only to discover when going through their notebooks that they had it right. They are my go-to resource for field-wide trends.

This year and future goals

In 2023, we continued our research on the trajectory of AI and its potential impacts. We produced almost twenty research reports, covering trends in ML hardware, scaling, and algorithmic improvements, as well as AI’s potential impact on automation and economic growth. We also updated and maintained our database of notable ML models, adding hundreds of new models.

We’ve also had many accomplishments this year outside of research. We successfully engaged with policymakers, media, and the AI industry to help share our ideas. We also raised over $7 million in funds, made multiple hires, updated our website to improve its style and our data visualizations, and ran two mentorship programs.

Next year, we intend to continue our research into the drivers of AI and on AI’s effect on economic growth. We will also work to strengthen the organization by diversifying our funding sources, developing our relationships with governments, and improving our headhunting capabilities.

Summary of key findings

  • We analyze trends in the performance of ML hardware and find:
    • Lower-precision number formats on specialized hardware can improve performance in ML workloads by an order-of-magnitude compared to the traditional FP32 format. More.
    • Computational performance in FLOP/s has doubled every 2.3 years for both general and ML-specific GPUs. Computational price performance in FLOP/$ has doubled every 2.1 years for ML GPUs and 2.5 years for general GPUs. Energy efficiency in FLOP/s/W has doubled every ~3 years. More.
    • Memory capacity and bandwidth has doubled much more slowly, every ~4 years. More.
    • The recent US Executive Order on AI establishes reporting requirements for AI models. We analyze the current data on models trained on biological data, finding one protein language model exceeds the mandated threshold, and ambiguity around models fine-tuned on biology data or trained on mixed data. More.

    • We investigate the output from key industry AI labs, finding that Google, OpenAI, and Meta are leading AI industry research across citations, size of training runs, and key algorithmic innovations that underpin large language models. Leading Chinese companies such as Tencent and Baidu have a markedly lower impact on all of these metrics. More.

Algorithmic improvements

  • Several techniques can improve the performance of trained large language models by an amount equivalent to increasing training compute by 1-2 orders of magnitude. These techniques incur little additional computational cost (<10% of pre-training compute, and often <1%). More.
    • It is also possible to improve the performance of trained models by an amount equivalent to increasing training compute by 1-2 orders of magnitude, at the cost of increasing inference compute by 1-3 OOM. More.

    • Model recycling via kickstarting or model augmentation likely only provides modest benefits in reducing foundation model training costs. More.

Economics of AI

  • Leading theories of economic growth suggest that AI that could substitute for human workers in most tasks could lead to a ten-fold increase in economic growth in frontier economies. Key questions remain about the intensity of regulatory responses to AI, physical bottlenecks in production, the economic value of superhuman abilities, and the rate at which AI automation could occur. More.
  • Predicting which occupational tasks will be automated by AI is an important but unsolved challenge. We’ve found substantial disagreement between the predictions made by different approaches. The field has significant room for improvement, such as in making realistic deployment assumptions and linking predictions to measurable AI progress. More.

Other topics

  • We estimate the maximum energy efficiency of CMOS microprocessors, measured in FLOP per Joule of energy dissipated (FLOP/J). We estimate a roughly 50% chance that CMOS processors will hit an energy efficiency ceiling at ~6e13 to 1.5e15 FLOP/J (using 16-bit precision), which would be a ~200x improvement on the existing state-of-the-art. More.
  • We use a novel, speculative methodology to estimate the training requirements of AI that can substitute for most economically useful tasks, and arrive at an estimate of between 1e27 and 1e41 effective FLOP (i.e. adjusting for algorithmic progress starting from 2024). More.

Overview of research projects

We produced 19 research outputs in 2023 after our previous impact report was written, including papers, reports, databases and dashboards. These cover many crucial topics for the future of AI, including trends in machine learning, algorithmic progress, the economics of AI and more.

Overview of non-research activities

Besides our impressive research outputs, we are continuously investing into our organization.


We have raised 7 million USD to cover our expenses through September 2025 through a couple of grants from Open Philanthropy. We also received a notable $100,000 donation from Carl Shulman, and several minor donations from individuals.

We are actively putting efforts into diversifying our funding, such as applying for an NSF grant and initiating a sponsored collaboration with the Stanford AI Index. If you are interested in making a large donation, please contact us. We also appreciate individual contributions of any amount.


We hired senior researcher David Owen, who has taken a prominent role in the organization through his research and management. We also hired data scientist Robi Rahman and multiple data contractors to scale up our existing data efforts.


We have updated our website’s style, look and graphs, to better reflect the quality of our work. We plan to continue improving our visualizations to create quality graphs that help communicate our most important findings.

Mentorship Programs

We ran two mentorship programs, including a private mentorship program in March with students from MIT and Harvard, and a public mentorship program, in collaboration with the Forecasting Research Institute, aimed at women, non-binary people, and trans people of all genders.

Overview of impact

Epoch AI continues to support better communication on AI. In particular, we have had some notable mentions of our work by media outlets, including TIME Magazine, The Economist, MIT Technology Review, and the New York Times. We also gave public talks about our work in Physics World, EAG London 2023, VPRO Tegenlicht and elsewhere.

Conferences and workshops

We frequently engage experts to receive feedback on our work. For instance, we participated in the 7th Annual Center for Human-Compatible AI Workshop, and the 2023 IEEE International Conference on Rebooting Computing.

We also have presented our work at the UVA Economics of AI seminar, MIT Economics of AI Tea, MIT Economics of AI seminar, AI Scaling workshop at MIT, the MIT FutureTech Lab, and elsewhere.

Mentions in industry, research and scientific publications

Epoch AI continues to be a relevant resource for developers and researchers at the cutting edge. We have had some notable mentions in scientific articles, industry communications, and books, including in François Fleuret’s The Little Book of Deep Learning, Google’s announcement of Bard and NVIDIA’s blog.

In total, our work has accumulated hundreds of citations in 2023 from academic and industry publications. Some papers that have received significant attention throughout the year are Compute Trends Across Three Eras of Machine Learning and Will We Run Out of ML Data? Evidence From Projecting Dataset Size Trends.

Engagement with policymakers

We have seen a surge of interest in AI policy in the past year. We have been able to support the ongoing conversation on managing AI technologies by providing up-to-date evidence on relevant topics.

In 2023, we supported the work of the UK Department for Science, Innovation and Technology and the Joint Research Centre of the European Commission through consultations and collaborations. In particular, the UK DSIT discusses our work on Frontier AI: capabilities and risks. We also submitted evidence to a House of Lords inquiry on language models.

Next year’s goals and funding needs

Research goals

Model of AI and growth

Throughout 2023, we have been actively developing a sophisticated model of AI and economic growth based on semi-endogenous growth theory, which will build upon the compute-centric model from Davidson (2023). This model takes an alternative modeling approach, incorporating more realistic dynamics of investment and several improvements over Davidson’s model.

We intend to release this model during the coming year, after a thorough process of review and testing. The release will consist of a whitepaper and an interactive model. We also plan on delivering several workshops among economists in government and academia to make the model widely accessible as a standard tool of analysis.

Drivers in AI

We plan to continue our research into the main drivers of AI, and possible bottlenecks the field might encounter in the future. This will encompass work on algorithms, overcoming data limitations, parallel training, the cost of training AI systems and more.

Data on machine learning

We plan to keep expanding our database of notable ML models, and in particular strive to comprehensively curate information on systems trained using large amounts of compute.

We also plan on developing a brand new database of innovations in ML, that will help support research into algorithmic progress.

Organizational goals

Stakeholder engagement

We foresee that interest in AI will continue surging in 2024, and that our input to policy will continue to be critical to informing decision-makers worldwide. To this end, we plan to develop our relationships with the US, UK and EU governments to provide evidence relevant for the regulation of AI.


It is important to us to grow to accommodate new projects and to expand the expertise we have access to. We plan to hire 1-2 senior staff and 1-2 specialists, increasing our headcount to 14-16 FTE. We also want to improve our headhunting capabilities, and in particular our ability to recruit senior talent.

Project management

Over the last year we have taken significant steps towards improving the quality of our outputs, including a more thorough review process and more engagement with external experts. We want to keep improving our internal processes for project management and review to ensure the highest level of quality while keeping a high productivity. We aim to produce between 24 and 30 research outputs over the next year.

Diversifying our funding

We want to establish relationships with 1-2 additional funders to solidify the independence and continuity of the organization. This might include some commissioned work from stakeholders aligned with our core mission.

Website and brand

Continuing our process of rebranding, we want to strengthen our public image and the quality of our visualizations. We are in the process of hiring a full-time product and data visualization designer who will own this. Our goal is to have a recognizable style and produce graphs that help communicate our most important findings.
