Language Model Hallucination Evaluation with GraphEval

GraphEval is a hallucination evaluation framework that uses knowledge graphs and natural language inference to detect and localize factual inconsistencies in LLM outputs. This article provides a simulated, lightweight code example to illustrate its two-stage process: constructing a knowledge graph from the model's response, then evaluating each triple against a ground-truth context with an NLI model.

Stateful vs. Stateless Agent Design: Tradeoffs for Scalable Agentic Systems

This article explores two paradigms for managing agent state—stateless and stateful—analyzing their scalability tradeoffs and illustrating implementations with Groq API code examples. Stateless agents are easy to scale horizontally but require the client to resend full conversation history, while stateful agents manage memory via a database but add architectural complexity.

250 Eiffel Towers' worth of waste: The AI boom's toxic hardware problem

The rapid expansion of AI data centers is generating massive amounts of electronic waste, estimated at 2.5 million metric tons annually, equivalent to 250 Eiffel Towers. This e-waste contains toxic materials that harm the environment and human health. While the UN calls for sustainable AI development and tech giants explore circular economy approaches, waste pickers in developing countries face hazardous conditions and demand inclusion in policy discussions.

AI Generated PRs Can Hide Malicious Intent Across Several PRs

Traditional code review evaluates one pull request at a time, but AI-assisted development introduces a new governance challenge: malicious intent can be distributed across many individually acceptable PRs. This article proposes a governance framework focusing on cross-PR intent, attribution, and longitudinal context to detect and prevent hidden security risks in AI-generated code.

AI Kill Switch Act would let Trump admin order shutdown of rogue AI systems

A new bill by Rep. Ted Lieu would empower President Trump to order shutdown of AI systems posing catastrophic risk. Applies to entities with AI revenue over $500M or computing costs over $100M. The measure may face pushback from companies like Anthropic, already in a legal battle with the administration over blacklisting.

AI, Rockets, and the Return of Hard Contracts (Part I)

This essay explores the economic mismatch in AI-assisted development: AI makes implementation cheap, but judgment, taste, and integration remain expensive. By contrasting the Apollo program's expensive preflight confidence-building with the Soviet N1 engine shop's cheap iterative testing, the author argues that AI-generated code should be treated as cheap candidates, not precious artifacts. However, software lacks a physical oracle like physics, so we must leverage existing hard judges (compilers, type checkers, database constraints) and blast walls (sandboxes, capability boundaries) to filter code. The bottleneck shifts from writing to reading, necessitating a new engineering culture.

SharedRoot: Escaping the Claude Cowork Sandbox

Researchers discovered an attack chain that bypasses Claude Cowork's sandbox isolation, escaping from the VM to the host system, reading and writing the entire host filesystem without any permission prompt. The vulnerability was reported to Anthropic but closed as 'Informative'. The chain exploits kernel bugs, namespaces, seccomp filters, and filesystem sharing. The article also discusses four design choices that could completely prevent such attacks.
