Memory Has a Budget: Compress Long-Running Context by Value, Not Age

TL;DR for operators Fofadiya and Tiwari propose a context-management system for long-running LLM interactions that does more than summarize old conversations.1 It scores historical turns by relevance, recency, dialogue dependency, and coherence, then applies a three-level policy: retain high-value turns verbatim, summarize medium-value turns, and remove low-value history when the context budget requires it. ...

More Compute, Different Jobs: Choosing Inference-Time Reliability Controls

TL;DR for operators When one model answer can trigger a consequential downstream step, spending more inference compute before trusting that answer can help—but the form of that spending matters. In the reported experiment, generating several reasoning attempts and aggregating the answer that repeatedly emerged increased verified acceptance from 56.2% to 64.9%. Asking the same model to critique and revise itself produced a smaller increase, from 47.2% to 50.6%. Adding a second model did not improve the reported acceptance rate: 47.4% of outputs survived cross-model verification versus a 48.7% single-model baseline. ...

Spend Verification Where Risk Is Highest

TL;DR for operators A long generated report can contain low-risk statements alongside claims that deserve much stronger evidence checking. Applying the strictest verification rule everywhere spends verifier capacity without distinguishing where factual failure is most likely. FACTOR turns that problem into a routing decision. The framework estimates uncertainty for individual claims, applies progressively stricter evidence requirements as estimated risk rises, and then selects among multiple generated candidates. In the reported benchmark, FACTOR reached a FActScore of 42.3 versus 36.8 for static verification while reducing average verification calls from 194.0 to 41.9.1 ...

When Threat Scores Start Steering the Honeypot

TL;DR for operators A deception system that responds the same way whether a session looks routine or highly suspicious leaves useful threat information unused. Chameleon tests a different design: estimated threat severity changes how aggressively the honeypot searches for engagement settings and which deception paths receive reinforcement, rather than merely changing the terminal reply. ...

Better Ideas, Narrower Search: Designing LLM Brainstorming as a Portfolio

TL;DR for operators LLM brainstorming should not be evaluated only by how good its individual ideas look. In a product-ideation experiment, GPT-4 generated ideas with higher average purchase intent than human participants and was seven times as likely to place an idea in the top decile. Yet its idea pools were also much more concentrated around similar regions of the solution space. ...

When the Transcript Stops Being Evidence: Re-Sonance and the Limit of LLM Speech Repair

TL;DR for operators A downstream AI model can rescue imperfect upstream output only while enough evidence survives to reconstruct what was lost. Re-Sonance1 makes that boundary unusually clear: after speech recognition, LLM correction lowers Word Error Rate from 21.58 to 13.74 for mild dysarthria and from 23.70 to 17.88 for moderate dysarthria, but severe-case WER rises from 83.77 to 84.40 and Match Error Rate rises from 87.50 to 90.96. Lower error rates mean the reconstructed wording is closer to the intended transcript. ...

Move the Goalposts on Purpose

TL;DR for operators A fixed rubric is a depreciating training asset. Early in reinforcement learning, it may be too demanding to distinguish one weak answer from another. Later, once the model learns to satisfy it, the same rubric becomes too easy. The score survives; the information content does not. EvoRubrics trains the evaluator alongside the model.1 A Policy LLM produces candidate answers, a Rubric Generator produces candidate evaluation criteria, and an external judge scores every answer against every rubric. The policy is rewarded for satisfying the evolving criteria. The rubric generator is rewarded for producing criteria that separate stronger from weaker answers, cover different dimensions, remain anchored to desired preferences, and help the policy revise its responses. ...

Cache Me If You Can: Why Enterprise AI Needs Latent Working Memory

A codebase is not a paragraph. Neither is a litigation folder, a clinical case file, a customer-support history, a policy archive, or the slow-motion disaster known as “all meeting notes since March.” Yet many enterprise AI systems still treat long context as a heroic prompt-engineering problem: push more text into the model, pray the key detail survives attention, and call the bill “innovation.” ...

Laws and Order: Turning LLM Brainstorming into a Research Hypothesis Workflow

Brainstorming Is Cheap; Research Judgment Is Not Brainstorming with an LLM is easy. Ask for ten research ideas, wait a few seconds, and receive a confident menu of things that sound just plausible enough to be dangerous. Turn up the temperature and the machine becomes “creative.” Wonderful. We have successfully automated the whiteboard intern. ...

Filter Bubble Bursts: When Common Crawl Beats Clean Data

Cleaning is comforting. Every serious AI team has some version of the same ritual. Remove spam. Remove repetition. Remove bad language detection. Remove low-quality pages. Remove documents that look too weird, too short, too duplicated, too uneducational, too internet. Then hope the model learns from the respectable leftovers. That instinct is not foolish. In small or compute-constrained training runs, filtering often helps. The expensive mistake is treating that local truth as a permanent law. ...
