KV-streams for Efficient Compaction in Agentic Reinforcement Learning

Emiliano Penaloza, Dane Malenfant, Dheeraj Vattikonda +15

Scaling the horizon of agentic LLMs is bottlenecked by the need to fit ever longer context traces in GPU memory. Context compaction has been the most popular mechanism to alleviate…

GlyphBench: A Playground for Language-Model Reinforcement Learning

Roger Creus Castanyer, Marc-Alexandre Côté, Matthew James Sargent +3

We introduce GlyphBench, an environment suite for reinforcement learning (RL) post-training of language-model agents, with over 360 tasks spanning diverse games. GlyphBench renders…

unix-ctf: Procedural Environments for Unix-Competence Reinforcement Learning

Geoffrey Bradway, Roger Creus Castanyer, Lorenz Wolf +3

Unix competence is the ability to use shell and operating-system primitives as first-class tools, not merely to write programs through a terminal. Current terminal benchmarks tend…

PopuLoRA: Co-Evolving LLM Populations for Reasoning Self-Play

Roger Creus Castanyer, Geoffrey Bradway, Lorenz Wolf +3

We introduce PopuLoRA, a population-based asymmetric self-play framework for reinforcement learning with verifiable rewards (RLVR) post-training of LLMs. Teachers and students are…

Frequency and Generalisation of Periodic Activation Functions in Reinforcement Learning

Augustine N. Mavor-Parker, Matthew J. Sargent, Caswell Barry +2

Periodic activation functions, often referred to as learned Fourier features have been widely demonstrated to improve sample efficiency and stability in a variety of deep RL algori…

Temporally Extended Successor Representations

Matthew J. Sargent, Peter J. Bentley, Caswell Barry +1

We present a temporally extended variation of the successor representation, which we term t-SR. t-SR captures the expected state transition dynamics of temporally extended actions…

Using Forwards-Backwards Models to Approximate MDP Homomorphisms

Augustine N. Mavor-Parker, Matthew J. Sargent, Christian Pehle +3

Reinforcement learning agents must painstakingly learn through trial and error what sets of state-action pairs are value equivalent -- requiring an often prohibitively large amount…
