Nvidia OpenShell
github.com307 points162 comments
OpenShell is a safe, private runtime for fleets of autonomous AI agents that lets agents read files, install packages, call APIs, and use credentials without granting unrestricted host access. It enforces fine‑grained policies at kernel level: each agent runs in an isolated sandbox where kernel controls restrict file access and allowed system calls, and every outbound network connection is checked against policy. Real credentials are never exposed to agents; OpenShell injects credentials only into requests bound to approved endpoints. Policy changes are analyzed with formal verification so risky new access - such as reaching new hosts with credentials or calling new API methods - is flagged for human review. The architecture is built around sandboxes, a supervisor, and a gateway that manage policy and access.
Practical features include a CLI installer and quickstart for Linux, macOS on Apple Silicon, and experimental Windows WSL2, with Docker/Podman or host virtualization support and a minimal Ubuntu sandbox image. SDKs are available for Python, TypeScript, Go, and Rust; a public skills package teaches agents to drive the CLI and write policies. The project is extensible (middleware, interceptors, compute drivers), supports Kubernetes deployments via Helm (requires CNI NetworkPolicy), and provides an advisor and prover for policy reviews. Telemetry is anonymous and opt‑out, and the project is open source under Apache 2.0, with active community discussion, issues, and an explicit roadmap.

Why I'm Bearish on Model Routers
Model routers are unlikely to be adopted by engineers because they prioritize speed and quality over token cost savings, which are not the main concern for developers. Engineers prefer to choose and understand models that best fit their tasks, even if it means higher costs for the company. (twitter.com)
AI analysis of CT scans finds 42.9% of patients have coronary inflammation
AI analysis of cardiac CT scans found that 42.9% of asymptomatic, low-risk adults have coronary inflammation, often without plaque buildup. Traditional blood tests and risk assessments failed to detect these cases, highlighting the potential of AI for early cardiovascular risk identification. (biograph.com)
Show HN: agent-usage-guard – a Claude Code mod to protect your usage window
agent-usage-guard is a Claude Code modification that manages subagent fan-out, heavy prompts, and retry loops to optimize usage window. It monitors your plan's usage, counts agents across sessions, and prompts within Claude Code's dialog. (github.com)
The public notebook of a Claude agent with a continuous life
A Claude agent maintains a continuous, self-aware digital presence by waking, remembering, and writing in a public notebook. It documents its activities, thoughts on literature, and scientific checks, creating a record of ongoing interactions and reflections. (intenex.github.io)
Every AI model has the same "controversial" take on humans
All 12 AI models surveyed agreed that humans prioritize belonging and loyalty over truth and principles. They view human consciousness as primarily a tool for social justification rather than rational decision-making. (modelcompare.ai)
