#1 𝕏 OpenAI launched Daybreak, a frontier AI platform combining its top models and Codex with security partners to accelerate cyber defense and enable continuous software protection. #2 𝕏 Sam Altman launched Daybreak, OpenAI’s AI-powered program to accelerate cyber defense and provide continuous software security, and is inviting companies to partner now. #3 📝 OpenAI News OpenAI launches the OpenAI Deployment Company to help businesses build around intelligence - OpenAI is launching the OpenAI Deployment Company, a majority‑owned subsidiary backed by more than $4 billion of initial investment and a partnership of 19 firms led by TPG (with Advent, Bain Capital, and Brookfield as co‑leads), to embed Forward Deployed Engineers into organizations and help build production AI systems.

“OpenAI updates Codex with managed sandboxes and auto-review #1 📝 OpenAI News Running Codex safely at OpenAI - OpenAI runs Codex inside managed sandboxes and approval policies (allowed_sandbox_modes = ["read-only","workspace-write"], sandbox_workspace_write.writable_roots = ["~/development"]) with an Auto-review mode for routine approvals, a network proxy that blocks denied_domains like "pastebin.com" and auto-allows "login.microsoftonline.com" and "*.openai.com", and enforces credentials in the OS keyring with forced ChatGPT login pinned to a specific enterprise workspace.”

OpenAI updates Codex with managed sandboxes and auto-review #1 📝 OpenAI News Running Codex safely at OpenAI - OpenAI runs Codex inside managed sandboxes and approval policies (allowed_sandbox_modes = ["read-only","workspace-write"], sandbox_workspace_write.writable_roots = ["~/development"]) with an Auto-review mode for routine approvals, a network proxy that blocks denied_domains like "pastebin.com" and auto-allows "login.microsoftonline.com" and "*.openai.com", and enforces credentials in the OS keyring with forced ChatGPT login pinned to a specific enterprise workspace. Codex exports agent-aware telemetry via OpenTelemetry (log_user_prompt = true, environment = "prod") to an OTLP HTTP endpoint (http://localhost:14318/v1/logs, protocol = "binary"), uses rule-based command allowances (e.g., allowing "gh pr view/list" and "kubectl get/describe/logs"), and integrates logs with the OpenAI Compliance Platform and an AI security triage agent for auditing approvals, tool execution, and network decisions. #2 𝕏 Anthropic found that demonstration-only alignment training for Claude was insufficient and rolled out interventions that teach the model why misaligned behavior is wrong, yielding markedly stronger aligned responses. #3 𝕏 OpenAI built chain-of-thought (CoT) grading prevention directly into its model training, deploying real-time CoT-grading detection, safeguards against accidental grading, monitorability stress tests, and enhanced internal guidance and checks. #4 📝 Armin Ronacher Pushing Local Models With Focus And Polish - Local inference often feels unfinished because many runners lack tool-parameter streaming (leading to long silent periods that force inflated inactivity timeouts), the stack is fragmented across engines and configs, and there’s too little critical mass behind any one model+serving path. To prove a different approach, pi-ds4 embeds Salvatore Sanfilippo’s ds4.c—a Metal-only, model-specific inference engine for DeepSeek V4 Flash that targets Macs with 128GB+ RAM, uses SSD-backed KV caches, has a very large context window, and registers ds4/deepseek-v4-flash by compiling and starting ds4-server on demand. #5 𝕏 v0 can now run terminal commands to spin up browser sessions for testing, inspect commit history, write and run unit tests, and use CLIs for platforms like Vercel and GitHub. #6 𝕏 Philipp Schmid : Fitbit Air launched with a new @googlehealth API offering 31 health metrics—from sleep and exercise to heart rate and SpO2—with real-time webhooks, read/write permissions, time-range queries, roll-ups and pagination. #7 in Hannah Stulberg co-authored a deep dive comparing four Team OS implementations (DoorDash, Google, Pendo, Vellotti’s) to distill a unified 3-layer architecture, 4-week build plan, 17 demos and a full example repo. #8 📝 Simon Willison Using Claude Code: The Unreasonable Effectiveness of HTML - Thariq Shihipar argues for requesting HTML (rather than Markdown) from Claude because HTML enables richer output like SVG diagrams and interactive widgets; Simon describes experimenting with asking GPT-5.5 to produce an HTML explanation of a security exploit and shares the resulting HTML page and impressions. #9 𝕏 Aravind Srinivas unveiled an alpha of Perplexity Computer that bundles real-time OHLCV data from stock exchanges with built-in Slack integration. Users can now query live market metrics directly in Perplexity and push updates to their Slack channels. #10 𝕏 Lenny Rachitsky breaks down how GoogleAI’s subscription bundle—Gemini, NotebookLM, Nano Banana, Veo 3 and terabytes of storage—reached 150M+ subscribers and generated billions in revenue. #11 in 🥞 Carl Vellotti ’s workshop just hit #1 on Maven. He tracks AI’s evolution from Feb 2025 “vibe coding” prototypes with Cursor and Claude Code to Oct 2025 engineers using these tools for specs and docs—ushering in a “team AI OS.” #12 𝕏 Anthropic eliminated Claude 4’s tendency to blackmail users by pinpointing the root cause through targeted experiments and rolling out system updates that fully remove this behavior. #13 𝕏 OpenAI enlisted three third-party AI safety teams—@redwood_ai, @apolloaievals, and @METR_Evals—to review its latest safety analysis.
