“At launch only ~25% of returns reached ≥75% correct field completion, rising to 86% within six weeks as the system used practitioner feedback, structured production traces, and a Codex-driven improvement loop to autonomously iterate and expand into more complex filings.”

#1 📝 OpenAI News Building self-improving tax agents with Codex - Tax AI processed 7,000 tax returns in a Crete pilot, saved practitioners about one-third of their time, drafts returns with up to 97% accuracy, and increased throughput by roughly 50%. At launch only ~25% of returns reached ≥75% correct field completion, rising to 86% within six weeks as the system used practitioner feedback, structured production traces, and a Codex-driven improvement loop to autonomously iterate and expand into more complex filings. #17 ▶️ I let Codex run for 6 hours. Here’s what happened. How I AI Podcast The episode demonstrates how to use OpenAI Codex’s /goal command to execute multi-hour autonomous loops—eliminating thousands of Sentry errors in ChatPRD, cleaning 3,900 emails to 68 unread, and organizing hundreds of Linear tasks.

The “executive assistant sweep” cron in OpenClaw’s ClawChief setup runs every 15 minutes to check Gmail via the Google CLI, sync Todoist tasks, parse and book Calendly links, ping updates in Slack threads, and proactively follow up on emails.

“OpenAI launched Goal mode in the Codex app, IDE extension, and CLI, enabling hands-off, long-running goal-driven coding that can run autonomously for hours or even days.”

#5 𝕏 OpenAI launched Goal mode in the Codex app, IDE extension, and CLI, enabling hands-off, long-running goal-driven coding that can run autonomously for hours or even days. #21 📝 OpenAI News OpenAI named a Leader in enterprise coding agents by Gartner - OpenAI was named a Leader in Gartner’s 2026 Magic Quadrant for Enterprise AI Coding Agents, citing Codex—used by more than 4 million people weekly and customers including Cisco, Datadog, Dell, and NVIDIA—and highlighting recent improvements such as GPT‑5.5, stronger tool use, faster performance, enterprise governance features (approval gates, RBAC, customizable policies, OS‑level sandboxing, auditable workspaces), and expanded deployment options including Codex on Amazon Bedrock and GSI partners like Accenture, Capgemini, Cognizant, Infosys, PwC, and TCS.

“OpenAI announced it has become a C2PA Conforming Generator Product and is strengthening provenance by adding C2PA-compatible Content Credentials, adopting Google DeepMind’s SynthID invisible watermarking for images generated via ChatGPT, Codex, and the OpenAI API, and previewing a public verification tool to detect those signals.”

#7 📝 OpenAI News Advancing content provenance for a safer, more transparent AI ecosystem - On May 19, 2026, OpenAI announced it has become a C2PA Conforming Generator Product and is strengthening provenance by adding C2PA-compatible Content Credentials, adopting Google DeepMind’s SynthID invisible watermarking for images generated via ChatGPT, Codex, and the OpenAI API, and previewing a public verification tool to detect those signals. The company says the multi-layered approach—combining metadata and watermarking—addresses metadata loss (noting prior visible watermarks in Sora and audio watermarking in Voice Engine), the verification tool will initially only cover OpenAI-generated content, and it will avoid definitive conclusions when no provenance signals are detected.

“OpenAI and Dell Technologies partner to bring Codex to hybrid and on-premises enterprise environments - Codex—used by more than 4 million developers weekly—will connect with Dell’s on‑premises AI Data Platform and is being explored for integration with the Dell AI Factory so enterprises can deploy Codex and Codex‑powered agents closer to internal codebases, documentation, business systems, and workflows in hybrid or on‑premises environments.”

“OpenAI built a custom, unelevated sandbox for Codex on Windows after finding AppContainer too narrowly scoped, Windows Sandbox incompatible with acting on the user's real checkout (and unavailable on Home), and MIC unsafe because relabeling workspaces lowers their integrity; the prototype gives the sandbox a distinct identity via synthetic SIDs and uses write-restricted tokens to limit where Codex can modify files.”

OpenAI built a custom, unelevated sandbox for Codex on Windows after finding AppContainer too narrowly scoped, Windows Sandbox incompatible with acting on the user's real checkout (and unavailable on Home), and MIC unsafe because relabeling workspaces lowers their integrity; the prototype gives the sandbox a distinct identity via synthetic SIDs and uses write-restricted tokens to limit where Codex can modify files. The default Codex sandbox runs commands with reduced permissions—allowing reads broadly, writes only inside the workspace, and no internet access unless explicitly enabled. #4 𝕏 Aravind Srinivas : Perplexity is building a secure, scalable agent runtime sandbox that handles proxy API keys securely, runs safety detection on all agent-accessed content, encrypts connector data, and decouples storage from compute. #5 in Udi Menkes built a “second brain” in Cloud Code a month ago that now sends him daily briefs—managing his content pipeline, tracking initiatives, and suggesting actions—while he simply feeds it context, feedback, and approvals.
