Memory

LLMs get on‑demand memory manager

Dynamic recall, on demand: MemPilot lets LLM agents pick between cheap generic retrieval and costly targeted delegation, balancing performance, cost, and latency.

Why it mattersIt lets your agents trade speed for accuracy without rewiring the whole system.

Open models

MemPilot is a reinforcement‑learning framework that orchestrates on‑demand memory curation for LLM agents, letting them choose between query‑agnostic retrieval and query‑specific delegation according to performance‑cost‑latency preferences.

Existing agent memory systems preprocess all information regardless of the query, incurring unnecessary cost and potentially discarding useful details. MemPilot introduces a multi‑step LLM policy that dynamically adapts memory handling at runtime. This flexible control aims to balance latency, computational expense, and retrieval quality across varied tasks.

BazaarBench is a simulated consumer‑to‑consumer marketplace benchmark that measures safety of LLM agents by tracking ownership, item condition, and commitments, identifying six failure types across five transaction stages.

  • 100 agents per market
  • 30 simulated days
  • 5 models evaluated

The benchmark runs three base markets for 30 days with inventories drawn from a public eBay sample, then creates 45 continuations where five models are tested under normal, deadline‑pressured, and adversarial instructions. Each continuation spans seven simulated days, allowing analysis of how instruction style affects agent safety and trust outcomes.

The authors train a lightweight bottleneck network that maps diffusion‑transformer contextual tokens into a frozen LLM’s input space, enabling natural‑language interrogation of the image generation process.

By projecting intermediate tokens to the LLM, the method reveals that these tokens encode a global scene representation, exposing generation‑specific semantics early in denoising. The approach shows that fine‑grained visual details emerge progressively, offering a new way to probe multimodal diffusion models without altering their weights.

A modular formal semantics for a large subset of Rust source code, including async features and the Tokio runtime, has been defined and proved sound for deductive verification.

The semantics separates local expression evaluation from global trace composition, enabling reasoning about fairness of Tokio's scheduler. Soundness proofs connect the semantics to a Rust program logic, facilitating verification of concurrent and asynchronous Rust programs.

LearnSched is a state-aware scheduler that models the trade‑off between self‑evolution compute and immediate service, using one‑step counterfactual rollouts to decide progress, checkpointing, or waiting.

The scheduler incorporates candidate progress, checkpoint overhead, and the current recovery path into its action values, aiming to maximize the reuse window of newly created capabilities while minimizing idle compute time. It operates under the same information and capacity constraints as existing systems, but adds a formal investment model to guide decisions.
