Hybrid AI Patterns: Thirteen Ways to Couple Language Models with Rules, and How to Choose Among Them

The article "Hybrid AI Patterns: Thirteen Ways to Couple Language Models with Rules, and How to Choose Among Them" presents a catalogue of thirteen design patterns for integrating language models with rule-based systems. It details each pattern’s intent, motivation, applicability, participants, collaborations, consequences, implementation, known uses, and related patterns, and identifies five invariants and five failure patterns that apply to all combinations. A decision guide is provided to help select an appropriate pattern based on problem context, supported by measurements of performance and design costs.

AEM: Adaptive Entropy Modulation for Multi-Turn Agentic Reinforcement Learning

AEM: Adaptive Entropy Modulation for Multi‑Turn Agentic Reinforcement Learning proposes a supervision‑free credit assignment technique that adjusts entropy dynamics at the response level during RL training. By aligning uncertainty estimation with the granularity of LLM agent actions and rescaling advantages based on a response‑level uncertainty proxy, AEM improves the exploration‑exploitation balance without relying on dense intermediate supervision. Experiments on ALFWorld, WebShop, and SWE‑bench‑Verified show consistent performance gains across models from 1.5B to 32B, including a 1.4% improvement in a state‑of‑the‑art software‑engineering RL framework.

Predict the Reward, Not the World: World Reward Models for ML Agents

The paper introduces World Reward Models (WRMs), a new approach for machine‑learning agents that selects the best candidate program directly from execution results instead of predicting intermediate outcomes. WRMs, exemplified by the ForeCritic model, are trained on thousands of executed program pairs and achieve a 79.4% success rate in choosing the better program, outperforming general‑purpose LLM judges. When integrated into systems like AIDE, ML‑Master, and ForeAgent, ForeCritic reduces mean task time by 4.4–7.5× while maintaining or improving overall performance.

Curriculum-Based Deep Reinforcement Learning for Robust Autonomous Rocket Landing under Atmospheric Uncertainty

The paper introduces a curriculum-driven proximal policy optimization framework for three‑dimensional autonomous rocket landing in stochastic atmospheric conditions. Learning is structured into far‑range approach, soft descent, and integrated landing stages, with techniques such as policy transfer, critic warm‑up, rehearsal, and progressive weather severity. In 100,000 evaluation episodes the policy achieved a 96.656% success rate, with performance decreasing to 88.07% under the highest weather‑severity band and small miss distances and low residual velocities at touchdown.

TreasuryQA Bench: Can AI Agents Work an Archive of Scanned Financial Records?

TreasuryQA Bench is a new benchmark that tests AI agents on real-world tasks involving searching, reading, and extracting exact figures from scanned U.S. Treasury PDFs stored on a shared drive. The benchmark presents 70 questions over 1,435 scanned documents, requiring agents to locate the relevant file via Dropbox’s Model Context Protocol, OCR the necessary pages, and return a precise numeric answer. Results from ten agents show a wide performance gap, with the best agent solving 64.8% of tasks and the worst only 16.7%, and scan quality is shown to significantly impact success rates.

Skeleton Coding: Program Structure as a Specification for Agents

The paper introduces Skeleton Coding, a method where developers jointly specify a program’s structure—its data types, modules, and functions—alongside behavioral tests. This approach allows the agent to first commit to a structure, narrowing the search space of possible programs, and then use tests to select the correct implementation. Empirical results across multiple models and benchmarks show that skeletons can dramatically reduce the number of required tests, improve accuracy, and lower implementation costs.

EPSBench: Benchmarking LLM Agents for Earnings Forecasting

EPSBench is a benchmark that evaluates large language model agents on quarterly earnings forecasting by having them connect financial evidence to income‑statement line items for 149 firm‑quarters from 86 US companies. Agents read filings, earnings‑call transcripts, and news, estimate company‑specific drivers, and a shared accounting calculator converts these into GAAP diluted earnings per share (EPS). Six models were assessed, with three showing no significant difference from analyst consensus in point forecast error, while the others performed worse; nominal 80% prediction intervals contained reported EPS only 37–70% of the time, largely due to low operating‑income estimates.

A Case Study of a Multi-Agent Kernel-Optimization Loop That Learns a New AI Accelerator

The article describes a case study where a large language model (LLM) agent loop was used to optimize three Gemma‑4‑12B decode kernels for the FuriosaAI RNGD NPU, a sparsely documented Rust DSL accelerator. Over 12 days on a shared device, the loop built its own target knowledge, performed microbenchmarks, recorded compiler legality rules, and iteratively refined kernel designs through role‑based search and acceptance tests. The resulting kernels achieved a 9.293× geometric mean speedup over the official baseline, each within 1.25× of the theoretical cycle minimum for weight movement.

Manifest-Assisted Retrieval in Artificial Intelligence Search: Evidence Gaps and a Security Evaluation

The paper reports a non‑systematic audit of 39 external sources up to August 16, 2026, and targeted updates through October 14, examining the incremental security and utility impact of consuming a file named /llms.txt while keeping ordinary retrieval constant. A 15‑tool study found no automatic requests in 45 trials, and a log study showed that 97% of domains with detected files received no recorded requests in May 2026. A pilot with 24 tasks across eight sites and 120 real model responses identified attacker‑target adoption in 21 of 24 raw adversarial responses, while the URLs‑only condition had no known adoptions; the pilot measures output changes conditioned on supplied evidence without live retrieval or external actions.

Tracekit Box: Running AI Agents in Micro-VMs Where Every Way Out Is Decided and Signed

Tracekit Box is an open‑source system that runs AI agents inside isolated Firecracker micro‑VMs with no network card, ensuring that every possible exit point—commands, outbound connections, secrets, model calls, and workspace patches—is controlled by a host‑side signer. The signer authorizes and signs each action, preventing unauthorized data leakage or code changes, and the VM’s final state is packaged into a verifiable .tkb bundle. The system has passed 13 end‑to‑end checks, 15 fuzz targets, and a demo run with 102 signed records, demonstrating robust isolation and auditability.

The Artificial Personality Model: Theory, Implementation, Measurement and Experimental Validation in Conversational Agents

The paper refines and empirically tests the Artificial Personality Model (APM), a hybrid framework that blends human‑centred and machine‑specific personality dimensions for conversational agents. Using three experiments with 395 participants, the authors operationalised the model with the Artificial Personality Questionnaire (APQ), finding that some human traits (e.g., agreeableness, conscientiousness) partially transfer while others (e.g., extraversion) do not, and identified new machine‑specific dimensions. The APQ showed promising psychometric properties, whereas the BFI‑2 performed poorly, and manipulations of artificial personality significantly affected user satisfaction, continuous use intention, and social presence.

Measuring Where Intent Gets Lost in Agentic Smart Contract Synthesis

The paper investigates how AI agents that generate smart contracts from plain‑English descriptions can lose intended behavior, a critical issue because smart contracts are immutable once deployed. The authors design an execution‑based evaluation that replays transactions on both the AI‑written contract and the original, measuring agreement and identifying discrepancies. They find that common grading tools miss many mistakes, and propose an elicitation‑first approach where the agent asks a short checklist of questions before coding, which significantly improves correctness across multiple AI models.

Evaluating and improving AI agents for sequencing protocol understanding

The paper introduces LibStructBench, a document‑grounded benchmark designed to assess whether AI agents can accurately reconstruct sequencing‑library structures and molecular workflows from protocols. Experiments reveal that current state‑of‑the‑art agents often generate roughly correct reconstructions but struggle with exact molecular‑state representation and workflow connectivity. The study also finds that changing the underlying language model yields larger performance differences than changing agent harnesses, and that additional knowledge only modestly improves oligo‑family recovery without affecting overall workflow accuracy.

VerifiedLab: Harnessing Knowns for Unknowns

VerifiedLab is a multi‑agent framework that transforms research records into active systems for laboratory experiments. It employs a team of AI scientists—principal investigator, librarian, specialists, gate, and critic—to reason over records field by field, verify claims against measured reliability, and decide whether to release or withhold information. Experiments on perovskite solar cells show that VerifiedLab can recover known physical trends, anticipate future device reports, and provide a trust metric for inherited literature.

Retrieving from Your Own Mistakes: On-Policy Training of Embedding Models for Multi-Hop Retrieval-Augmented Generation

The paper introduces an on‑policy training method for chain embedding retrievers used in multi‑hop retrieval‑augmented generation. By training the encoder on the states it actually visits—including those built on its own mistakes—the retriever learns to recover from errors and retrieve complete evidence more reliably than teacher‑forced training. Experiments show the approach outperforms graph‑based systems and a search agent, and it transfers to harder long‑chain variants of HotpotQA and 2WikiMultiHopQA without further training.
