EP250: Compiling agent workflows into model weights

Title: Compiling Agentic Workflows into LLM Weights: Near-Frontier Quality at Two Orders of Magnitude Less Cost Source: http://arxiv.org/abs/2605.22502v1 Summary: This work proposes the 'subterranean agent' paradigm, which replaces external orchestration frameworks by compiling agentic workflows directly into the model's weights via fine-tuning. This foundational shift addresses the cost and latency bottlenecks of frontier-model prompting while providing a more efficient and private alternative for procedural task execution.

EP249: Mem-pi fixes AI amnesia with generative memory

Title: Mem-π: Adaptive Memory through Learning When and What to Generate Source: http://arxiv.org/abs/2605.21463v1 Summary: Mem-π presents a foundational shift in agent memory architectures by replacing static similarity-based retrieval with a dedicated generative model that produces context-specific guidance. This framework enables agents to dynamically adapt their memory usage, leading to substantial improvements in complex reasoning and long-horizon task execution.

EP248: 10x Faster AI Agents with JIT Compilation

Title: Agent JIT Compilation for Latency-Optimizing Web Agent Planning and Scheduling Source: http://arxiv.org/abs/2605.21470v1 Summary: This paper introduces Agent Just-In-Time (JIT) compilation, a novel architectural primitive that transforms natural language task descriptions into optimized, executable code plans. It represents a significant breakthrough in agentic efficiency by replacing traditional sequential loops with a compiled, parallelized execution framework that drastically reduces latency.

EP247: PEEK Cures AI Goldfish Memory

Title: PEEK: Context Map as an Orientation Cache for Long-Context LLM Agents Source: http://arxiv.org/abs/2605.19932v1 Summary: This work introduces 'context maps' as a novel architectural primitive for long-context agents, enabling them to cache and maintain structured orientation knowledge about recurring external datasets. By implementing a programmable cache policy for distilling and translating inference-time signals, it significantly improves efficiency and accuracy across multi-turn reasoning workloads.

EP246: Replacing AI manuals with programmable runtimes

Title: Formal Skill: Programmable Runtime Skills for Efficient and Accurate LLM Agents Source: http://arxiv.org/abs/2605.19604v1 Summary: This work introduces a foundational architectural primitive for agents that replaces informal natural-language instructions with programmable, stateful runtime skills governed by hook policies and action schemas. This shift from prompting to executable state machines provides a more enforceable and token-efficient control surface for reliable agentic workflows in real-world environments.
