Devin introduces Fusion, a model harnessing system that pairs a frontier model with a cost-effective model to improve efficiency, and announces its availability in Devin Desktop and CLI. Fusion achieves significant cost savings across coding benchmarks while maintaining frontier performance. The system works by running two parallel agents, each with its own persistent context and tools, and delegates tasks from the lead model to the sidekick model. Devin also shares findings on the benefits of using more expensive models in Fusion and the importance of tuning the harness for different model pairings.

A campaign is targeting Rust-lang members and popular crate owners with malware via video calls, using legitimate-seeming company profiles to gain trust. The attackers attempt to install malware or execute commands on the target's device. Previous attacks have compromised prominent Rust developers and the arrayref crate. The Rust community is advised to take extra precautions, including being suspicious of cold outreaches and verifying account security.

A new approach to confidence gates for large language models involves transforming generation systems to selectively predict high-confidence answers, calibrating raw scores into interpretable confidence, and selecting refusal thresholds based on business risk. This method aims to improve the reliability of language models by providing more accurate confidence scores and reducing errors. The approach includes building a realistic calibration dataset, extracting stable answer-level scores, training a calibrator, and designing a gate with three states: automatic answer, supplementary evidence or human review, and refusal. The goal is to find a risk-coverage balance point acceptable to the business, rather than simply maximizing confidence.

USQRD's research reveals that LLM confidence scores are systematically miscalibrated, leading to ineffective human-in-the-loop gates, and proposes alternative methods such as ensemble disagreement and retrieval-grounding checks to improve calibration. The study emphasizes the need for a reliability diagram to set per-action-class thresholds tied to the cost of being wrong. The findings have significant implications for the development of autonomous agents, highlighting the importance of external signals over introspective ones and the need for a discipline of drawing reliability diagrams and measuring coverage-at-fixed-error. The research also provides actionable recommendations for practitioners, including the use of ensemble disagreement and retrieval-grounding checks, and the importance of tracking false autonomy and needless escalation separately. By adopting these methods, practitioners can improve the calibration of their LLMs and develop more effective human-in-the-loop gates.

A two-year university study found that banning AI from classrooms results in worse student performance, with the no-AI group finishing last in both years. The study suggests that structured training and hands-on experience with AI can improve student outcomes. The researcher, Thibault Schrepel, concludes that universities should rethink blanket AI bans and invest in AI skills for faculty.

The growing demand for AI computing is driving a memory supercycle, with high-bandwidth memory (HBM) and DDR5 prices rising due to limited supply and increasing demand from cloud service providers and AI giants. This trend is expected to continue into 2026, with DRAM prices projected to rise more than 70% and impacting the consumer electronics market.

The AI sector's high demand for High-Bandwidth Memory (HBM) has led to a structural shortage of memory chips for consumer electronics, with manufacturers like Samsung and SK Hynix prioritizing HBM production, causing price shocks and supply constraints. This shift is driven by the high profit margins of HBM, which is 3 to 5 times more profitable than conventional DRAM and NAND flash. The shortage is expected to peak in 2026, with analysts forecasting record price increases and a historic decline in global smartphone shipments.

LMArena's Elo scores for language models have risen faster than expected, potentially due to increased persuasiveness rather than intelligence, and methodological changes to the leaderboard may have contributed to this discrepancy. The scores' correlation with time may not be linear, and the true relationship between Elo scores and model capabilities is unclear. Several possible scenarios are proposed to explain the discrepancy, including changes in model architecture, increased persuasion capabilities, and methodological changes to the leaderboard.

Implementing cooldowns on dependencies can prevent the majority of open source supply chain attacks by introducing a time delay between when a dependency is published and when it's considered suitable for use. This technique is empirically effective, easy to implement, and free to use with tools like Dependabot and Renovate. Cooldowns can reduce exposure to attacks by 80-90% and are recommended to be baked directly into packaging ecosystems.
