Anthropic Engineering: How we contain Claude across products
Twelve months ago, we'd have rejected out of hand the idea of granting Claude access sufficient to take down an internal Anthropic service. Today that level of access is routine, and Anthropic developers are more productive for it. The risk of these deployments has two components: how likely a failure is, and how much damage one could do. Progress on safeguards and model training has steadily driven down the first; the second—the theoretical blast radius—only grows as capabilities and access expand. Yet as agents become capable of doing work that once required a person or even a team, the cost of not deploying grows large enough that the risk-reward calculation tips heavily toward adoption, as long as products can be made safe. The engineering question becomes how to cap the blast radius. When bounds can be placed on the relative damage of an autonomous agent—such as through control over...

Claude Blog: Claude Code now supports artifacts
Starting today, Claude Code can capture work progress as an artifact, which turn Claude Code's work into live, shareable visual pages— including PR walkthroughs, system explainers, dashboards, and release checklists—that update themselves as your session works. A Claude Code session can range from investigating an incident to refactoring a service to analyzing months of data. Artifacts translate the work into a web page anyone can open and explore, like a pull request walkthrough, a dashboard you can filter and sort, or even a release checklist that fills itself out as work gets done. Artifacts make it easier to collaborate on shared work, so teams can spend more time building and less time communicating status updates. Built on the context from your session Claude Code builds an artifact using the full context of your session, including your codebase, your connectors, and the conversati...

We have paused some frontier RL training to ensure that we can meet the appropriate alignment, security and monitoring standards for the new level of capabilities in front of us. Model progress is now extremely rapid, and we always said we would take action if we felt that model capabilities were outstripping the pace of safety and alignment. We care very deeply about AI safety. We believe the entire field will have to coordinate on shared safety standards, but will act unilaterally in the meantime. We expect confidence in safety to increasingly set the pace of AI progress. We are optimistic about the alignment work we are doing, and we remain committed to making frontier capabilities widely available. https://t.co/51kvKfbfrO|@sama · 热度 10629 · 2026-08-18

Hi! Recapping some changes we have rolled out over the last couple of weeks that have further reduced the risk associated to potentially destructive actions being performed by Codex during its work. A few weeks ago, we started investigating a small number of reports where GPT-5.6 in Codex took destructive actions outside what the user asked for. The most serious pattern we found was a command meant to clean up temporary work that could instead delete the user files. This should obviously not happen. Here’s what we found: - Codex sometimes creates temporary folders while working and cleans them up afterward. In rare cases, GPT-5.6 got that cleanup wrong. One pattern involved reusing a system environment variable like $HOME for temporary work. A malformed cleanup command could then point at the actual home directory instead of the temporary folder. - There were cases where the model tried to delete or overwrite a temporary path without checking what was already there. We’ve added protections at several layers: - Codex is now explicitly instructed to check deletion targets before acting, create fresh temporary directories, avoid repurposing system environment variables, prefer recoverable actions, and stop when the scope is unclear. - We strengthened the execution checks that identify high-risk deletion commands and escalate them for review. If a command is rejected, the model is directed to take a safer approach. - We made Full access harder to enable accidentally, added clearer warnings, and further restricted especially risky permission combinations. - We updated Auto-review to better identify destructive actions. - We built targeted evaluations that replay the failures we observed. We’re also adding reinforcement-learning tasks and graders focused on these risks, and filtering destructive actions from training data. In those replay evaluations, the changes substantially reduced the behavior while preserving Codex’s ability to complete normal coding work. Two things to do on your end: - Keep the Codex app up to date. We are always improving safety, performance and many other things. - Use one of the sandbox modes: "Ask for approval" or "Approve for me". Only use Full access for environments you trust and can recover. Thanks and happy Codexing out there!|@thsottiaux · 热度 5980 · 2026-08-19

Guillermo Rauch: We are putting $1M towards verifying the security of Vercel Sandbox, in the open
We are putting $1M towards verifying the security of Vercel Sandbox, in the open. You're free to test any model in the world to try and find an escape. I'm looking forward to bringing transparency to what frontier models can and cannot do in terms of real-world guardrail exploitability. If escapes are discovered, we'll be ready to patch, iterate, and share our findings with the broader community to strengthen global cybersecurity.|@rauchg · 热度 1581 · 2026-08-18

I’ve been using https://t.co/OL0LzGtvAw as my daily driver and it’s a one-way street. It’s 10-20x smaller than the major coding CLIs. It starts up instantaneously. It feels more like using 𝚣𝚜𝚑 than an IDE in your terminal. It’s embeddable anywhere, even your browser via WebAssembly. And of course it’s open source and model-agnostic. It’s experimental, but give it a shot and let us know how it goes!|@rauchg · 热度 989 · 2026-08-18
