TL;DR: This is one of the most important and exciting opportunities in AI on the planet - please read on.
The British Open-ended Learning & Discovery Lab is creating the perfect place for paradigm breaking AI research in the name of open-source and open-science. We have agency, we funding, we have unprecedented amounts of compute*, but WE NEED YOU!
..and we have created the dream job for you: The BOLD Fellow. This job combines a fast-moving, high agency, collaborative environment with full academic freedom and a salary that pays the bills.
Apply by noon UK time on the 15th of September for this once in a lifetime opportunity to shape the history of our field and of our planet:

BOLD is hiring 🚀
Right now we are looking for two brilliant individuals to help us build the machine that invents the future. If you are up for a challenge and thrive in a fast moving, collaborative, mission driven environment, this is for you..!

Over this week, we'll be posting about papers from BOLD on show at the upcoming #ICML2026. Up first: LEO, led by @mitrma!
Typical approaches in goal-conditioned RL select a single goal that is completed later in the episode. This paper instead asks a simple question: what if *every* goal is used for labelling (and how could we do that efficiently)?
Check it out: arxiv.org/pdf/2605.23551

The world doesn't wait for you to decide on an optimal action... but that's how we treat most RL research! Real-time RL learns how (and when) to plan - all while the environment is progressing in real-time.

🛌💭Our next ICML paper is Dreaming in Code, led by @k_mitsides. In this work, LLMs are used as architects of experience: writing worlds in code that scaffold an RL agent towards long-horizon skills it could not discover alone!

🔦 Another #ICML2026 paper from BOLD, and this time it's a SPOTLIGHT led by @ClarisseWibault. In this work, we introduce Recurrent Structural Policy Gradient for Partially Observable Mean-field Games with Common Noise. Our algorithm learns more realistic history-dependent behaviour, while also leveraging known structure to benefit from faster convergence than model-free RL methods!
Check out the project page at: clarisse-wibault.github.io/r…, which includes links to our Mean-Field Game library, as well as a Google Colab example implementation!

🪩 Next #ICML2026 paper: DiscoGen, led by @AlexDGoldie. DiscoGen is a procedural generator of algorithm discovery problems for AI research agents, supporting the creation of over 100 billion diverse tasks! Tasks vary across many axes, such as their field of machine learning or datasets they use. They can even support different evaluations, such as the time an algorithm takes to train (speedrunning ⚡️), its energy usage (efficiency 🌱) or its performance 💪!
Check out the paper at: arxiv.org/pdf/2603.17863
Give the code a look: github.com/AlexGoldie/discog…
Or install the DiscoGen package for your research: pip install discogen
Couldn’t be happier to be a part of BOLD! Amazing people, amazing times ahead
Hello world :)
We are BOLD — the British Open-ended Learning and Discovery Lab!
BOLD is a new academic research lab fully focussed on paradigm breaking discoveries in fundamental AI. We work towards more efficient & open AI that is built around human needs and capabilities.
To pursue these breakthroughs, we pioneer new modes of collaboration in academia that are more focussed, resourced, agile, and collaborative. Rather than fragmenting resources, today we are sunsetting 5 of the UKs leading AI labs to join forces under our joined scientific vision.
Our vision is centered around three pillars:
⚡ Beyond backpropagation – questioning the foundations of the field.
🤝 Human-centric learning & discovery – treating humans as core to our algorithms
🤖 Embodied learning – fast learning and adapting methods that deal with the messy real world
BOLD is backed by @UKRI_News and @EPSRC with £30M – and this is just the beginning. We are urgently looking for partners and sponsors to 10x this.

1/ 🪩 Automating the discovery of new algorithms could unlock significant breakthroughs in ML research. But optimising agents for this research has been limited by too few tasks to learn from!
Introducing DiscoGen, a procedural generator of algorithm discovery tasks 🧵

My first paper with @JacksonMattT and @az_prd is out on arXiv!
Introducing MaskLAM: a simple, architecture-free tweak that makes Latent Action Models (LAMs) focus on agents ONLY: 4× higher returns, 3× better latent actions, and a step towards learning from unlabelled videos! ⬇️

Excited to announce our #RLDM2022 workshop "Temporal Representation in RL" on 11 June @BrownUniversity ⚡️
We have an amazing lineup of speakers discussing time in biological & artificial brains incl. @RichardSSutton, Marc Howard and @criticalneuro!
See: trirl.cc/
Come check out our new paper at ICLR2022! 🚨 We introduce a hierarchical generative model for videos, which continuously controls its hierarchical depth for processing.
⚡️Our new work with @az_prd titled "Variational predictive routing with nested subjective timescales" (#VPR) is presented at #ICLR2022 tomorrow 28 Apr at 10:30 am — 12:30pm BST.

VPR is an event-based hierarchical generative model for videos… 🧵👇

How do you learn about something exciting, new, and interdisciplinary? A syllabus of course!
Today I'm releasing my own version of a syllabus to go deeper on the Free Energy Principle and Active Inference jaredtumiel.github.io/blog/2…

I didn't go to work because a cat fell on my head and then a dog with shoes tried to do me justice.

Join us this afternoon to check our @Grail2020 @MICCAI2020 work age prediction using @DevelopingHCP brain surfaces presented by my student @az_prd

2 things to share! 1) A few days ago, our paper on Deep active inference with MC methods got accepted @ #NeurIPS2020🥳 2) We released this exciting work that connects DAI with episodic memory & subjective time resulting in the following very cool features for model-based agents:
Preprint Time!
Episodic Memory for Learning Subjective-Timescale Models arxiv.org/pdf/2010.01430.pdf
Basic idea: Store only "interesting" memories and learn dynamics between them. Plan actions to get to interesting states skipping the boring stuff.
This has many cool properties..1/6
