Finally, simple updates that diversify a model’s training data can make a difference. We added unrelated tools and system prompts to a simple chat dataset targeting harmlessness, and this reduced the blackmail rate faster. https://t.co/Ug95umaoRu

Claude's Constitution is now an audiobook, read by two of its authors, Amanda Askell and Joe Carlsmith. It includes a Q&A on the writing process, the philosophies that shaped the document, and how it might change as models become more capable. Listen at https://t.co/dKMfpeOblm https://t.co/792RQ4sAxc

We recently found some instances of CoT grading during the training of previously deployed models after building a system that scans all OpenAI RL runs for accidental CoT grading. We did not find clear evidence that these instances degraded CoT monitorability. https://t.co/GB1QeaeZ8A

Codex now works directly in Chrome on macOS and Windows. It’s even better at working with apps and sites in Chrome, and now works in parallel across tabs in the background without taking over your browser. To get started, install the Chrome plugin in the Codex app. https://t.co/pjtHd9gC69

With the new Chrome extension, Codex can quickly move through repetitive browser work, like navigating structured pages and complex data entry flows. Under the hood, it writes and runs code to navigate and complete tasks. https://t.co/6bfDlnK2U3

If a task needs multiple tools, Codex chooses the best one for each step. It uses plugins when they can handle the job, Chrome when it needs a logged-in website, and combines approaches as needed. https://t.co/3GvDouoPDi

Chain of thought monitors are a key layer of defense against AI agent misalignment. To preserve monitorability, we avoid penalizing misaligned reasoning during RL. We found a limited amount of accidental CoT grading which affected released models, and are sharing our analysis. https://t.co/0o3PLfafC4
