The AIXI Labs Research Fellowship is a quarterly, rolling opportunity for researchers worldwide to work on AI safety grounded in algorithmic information theory. Fellows pursue a focused research project with close mentorship from the core team, receiving a monthly stipend of £2,000–£3,500 and a compute budget. The fellowship is fully remote, with the option to work from London, UK.
AIXI Labs is a small, London-based non-profit conducting AI safety research into methods that are both general enough to describe powerful agents and provable enough to support real safety claims. The team, led by Cole Wyeth, Marcus Hutter, and Aram Ebtekar, bridges theoretical models of unbounded artificial superintelligence (AIXI) with modern LLM‑based agents to reduce existential risk from advanced AI.

Frequently Asked Questions (FAQs)
Here are the most frequently asked questions about the AIXI Labs Research Fellowship. These answers cover eligibility, benefits, the application process, and what fellows can expect from this remote AI safety programme.
What is the AIXI Labs Research Fellowship?
It is a quarterly, rolling programme that allows researchers to undertake a focused AI safety project under the mentorship of the AIXI Labs core team. Fellows work on bridging theoretical AIXI models with modern LLM‑based agents, receive a monthly stipend and a compute budget, and may work remotely or from London, UK.
Who can apply for the fellowship?
Applicants must have a research background at the PhD student level; for empirical projects, a master’s-level mathematics background plus substantial industry or applied research experience can also qualify. Strong skills in probability, statistics, information theory, and reinforcement learning are required, as well as a genuine motivation to reduce existential risk from advanced AI.
How much is the monthly stipend?
Fellows receive a monthly stipend of £2,000 to £3,500, plus a dedicated compute budget for machine learning experiments. The exact amount depends on the nature of the project and the fellow’s experience.
Is the fellowship fully funded?
The fellowship provides a generous monthly stipend and a compute budget, but it is not a fully funded scholarship covering all possible expenses. It is designed to support living costs and research activities during the fellowship period.
Are there any deadlines for applying?
Applications are reviewed on a rolling basis, typically in quarterly cycles. There is no fixed deadline; you may apply at any time, and if not selected initially, your application remains eligible for later rounds.
Can I work remotely?
Yes, the fellowship is fully remote. You may work from anywhere in the world. There is also an option to work from AIXI Labs’ office in London, UK, but physical presence is not required.
What kind of research projects are expected?
Fellows pursue self-directed projects that align with AIXI Labs’ algorithmic-information-theoretic approach to AI safety. Projects can range from foundational theory to empirical experiments with LLM‑based agents, and fellows are encouraged to produce papers, blog posts, or other community outputs.
How long does the fellowship last?
The fellowship typically runs for roughly one quarter (about three months). In exceptional cases, it may be renewed for additional terms based on performance and project needs.
Is prior knowledge of AIXI required?
No, prior expertise in algorithmic information theory or AIXI is not required. However, a solid grounding in probability, statistics, information theory, and reinforcement learning is essential to engage seriously with the theoretical models used.
How do I apply for the fellowship?
To apply, prepare a research proposal aligned with AIXI Labs’ agenda and submit your application via the official Google Form on the programme page. There is no application fee, and the process is entirely online.
