RAISE: Diagnosing Acquisition Collapse in Costly LLM Signals

Read the original on arXiv Machine Learning →

The paper introduces RAISE, a diagnostic framework that tests whether a costly large language model (LLM) signal provides enough pre-call information to justify selective use. It identifies the failure mode of acquisition collapse, where an LLM appears useful overall but lacks actionable evidence for individual decisions. The authors demonstrate RAISE with Structured Hypothesis Embeddings (SHE) and evaluate it across multiple study designs, showing that predictable incremental benefit, rather than average lift, indicates recoverable selective value.

Doomed from the Start: Early Abort of LLM Agent Episodes via a Recall-Controlled Probe Cascade

Large language model (LLM) agents solving multi-step tasks frequently commit to trajectories that are doomed to fail, yet continue to consume substantial inference compute before the failure becomes observable. We show that failure is predictable early from the agent's internal representations: lightweight per-round probes on hidden activations anticipate eventual episode failure as early as the first interaction round, where scorers reading only the agent's observable behavior are barely better than chance.

Root-Cause Attribution Is a Search Problem: Continual Search for Long-Horizon Agent Failures

The paper introduces Continual Search, an iterative framework that guides large language models to persistently search for diagnostic evidence in long AI agent execution logs, addressing the limitations of one-shot judgments. Evaluated on four existing RCA benchmarks and a new large-scale dataset called MegaRCA-Mix, Continual Search consistently boosts attribution performance, achieving a 40% F1 improvement for GPT‑5.5 on MegaRCA‑Mix. The results show that effective search can outweigh raw model scale, enabling lower-tier models to outperform higher-tier ones in root‑cause attribution tasks.

Beyond Depth and Width: The Information-Slack Dilemma in Streaming Test-Time Compute

The paper discusses how the same computational task can require different reasoning strategies depending on the order in which evidence arrives, introducing the concept of an "information‑slack dilemma." It argues that early computation may be useful only if its benefits outweigh the costs of later verification, invalidation, and recovery, and proposes a research agenda focused on selective recovery and predictive policies. The authors emphasize evaluating these approaches by separating early‑execution effects, deployment value versus full‑input alternatives, and the added value of predictive policies while considering shared‑resource costs.
