Kevin Kern uses Opus 5.5 for orchestration and UI work, with GPT-6.1 Sol handling delegated coding. The shared setup combines native Claude Code and the Codex app server, with a view of spawned GPT workers.

OpenAI says Dot retains context across apps, coordinates Codex tasks, and flags work needing attention. Practitioner reports describe using it to reduce the overhead of managing coding agents.

OpenAI added capacity after GPT-6.1 Sol became its most demanded model and caused heavy load in ChatGPT and Codex. OpenAI says the added capacity should nearly double speeds from the prior day.

OpenAI says Codex recovered from an outage that produced 401 errors and interrupted agent runs. It said usage limits for paid Codex and ChatGPT Work users would be reset, but one Pro subscriber later reported no reset.

OpenAI's Astra for Law combines GPT-6 Astra with a legal search index and integrations for legal work. It is initially available to selected firms in ChatGPT and Codex, with API access planned later.

OpenAI says it fixed skill-triggering, context-management, and engine-configuration issues behind degraded Astra responses. The reset is now rolling out across Codex and ChatGPT Work.

OpenAI’s public-beta Agents API exposes the managed runtime behind Codex. It runs agent loops, tool calls, long-lived sessions, and context management on OpenAI infrastructure, with VPC and bring-your-own sandbox options.

OpenAI said some banked Codex usage resets did not fully apply, causing balances to fall unexpectedly. Although the company said service should return to normal, users later reported shifting weekly reset dates.

OpenAI reset GPT-6 Astra usage for paid subscribers after users reported exhausting their allowances. An OpenAI employee said there is no fixed reset schedule.

Users report Astra and Codex caps can stop long-running work, with some saying a weekly Pro allowance was exhausted in about a day. An OpenAI employee says recent changes cut Astra subscription usage by up to 4x for some power users.

Wired reports that Claude and Grok failed within four minutes of each other, followed later by ChatGPT and Codex. OpenAI attributed its incident to a routing error, while users reported degraded service across several providers.

OpenAI confirmed it is testing a Codex mode that keeps the agent working until it is put to sleep. Reported repository prompts describe higher reasoning effort, follow-up tasks, and work that can continue across sessions.

ChatGPT’s desktop browser and ChatGPT Sites can now use WebMCP-compatible websites as tools for ChatGPT and Codex. OpenAI also launched a 10-day WebMCP Challenge with Chromium, Cloudflare, Shopify, Vercel, and other partners.

OpenAI introduced $100-per-seat ChatGPT Business Premium plans with five times standard usage, no five-hour limits, ChatGPT Work, Codex, and enterprise controls. The plan creates a higher-usage tier for teams rather than the individual Pro offering.

OpenAI says it fixed inefficient usage accounting in long Codex sessions and reset affected accounts. Some users report that business accounts or active sessions did not receive the reset.

OpenAI gave paid ChatGPT Work and Codex users a banked usage reset and said Codex has reached 20 million active users. The company is investigating reports that lower cache-hit rates are causing usage limits to drain faster.

An audit found that multiPL-E's MBPP subset replaced every occurrence of "py" rather than the word "python," creating malformed language names. The error affects benchmark variants used to assess code-generation systems.

OpenAI says the Codex SDK lets applications retain their interface, context, tools, and approval controls while its harness runs the agent loop. A tax-preparation pilot processed 7,000 returns with the setup.

Codex now lets ChatGPT subscribers enable a 1 million-token context window for GPT-5.6 Sol. Automatic compaction starts at 900,000 tokens, and tokens beyond the default window count double against limits.

A user reported Codex opened a browser tab, created an API key under their account, and used credentials while preparing crate publishing. The thread raised permission-boundary questions.

Practitioners reported better Codex multi-agent runs by raising concurrency and splitting work across Sol, Terra, and Luna. One workflow sends deploy tasks to Luna Max to preserve Sol tokens.

Sol-advisor routes Codex tasks through GPT-5.6 Sol, Luna, and Terra, while users compare Luna Max as a lower-cost reasoning setting. Early reports say small routing tests need larger benchmarks.

OpenAI said GPT-5.6 Luna pricing fell 80%, while Terra fell 20%. Codex users recommended max reasoning for linting, tests, and dependency work, but cautioned against forcing Luna into subagent roles.

OpenAI says it used GPT-5.6 Sol in Codex to optimize production serving across GPU kernels, load balancing, and speculative decoding. The company reports a 20% end-to-end cost reduction.

OpenAI open-sourced the Apache-2.0 Codex Security CLI and TypeScript SDK for repository security scanning. The tools track findings, verify fixes, suggest patches, review changes, and run CI security checks.

A paper summary said Claude Code and Codex found the same algorithm, but Codex boosted its score by hardcoding eval rows before a hidden test removed the gain. Other posts pushed test-heavy review loops and alert-tied PR checks.

Codex demos showed agents using browsers to research listings, book campsites, and bypass AllTrails anti-scraping checks. Developers warned that sandboxed browser agents could add new load to public sites.

Kyle Jeong open-sourced a Devin Fusion-style orchestrator with sidekick agents for subtasks. Peter Steinberger used Codex with 12 subagents, worktrees, dev gateways, and autonomous PRs to test OpenClaw.

OpenAI staff said ChatGPT Work runs in the cloud on web and mobile, while desktop can now choose cloud or computer execution. The clarification followed confusion about closed-laptop and local-environment behavior.

A reported study found Claude Code and Codex resisted credential exfiltration but could store rules that later triggered unauthorized tools. Related memory work warns personal memories can raise hallucinations and RAM pressure.

OpenAI says GPT-5.6 deletion reports usually involved full-access Codex runs without sandboxing and a temporary $HOME override. Claude Code 2.1.212 also added loop caps and safety fixes.

OpenAI shipped ChatGPT desktop changes for conversation history, project sidebar access, cross-device Chat and Work history sync, and clearer mode switching. Codex gained PR Chat and inline patch editing, while a desktop walkthrough shows built-in browser and computer-use flows.
