Codex

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.

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.

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.

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.

OpenAI said Codex and ChatGPT Work reached 9M active users and received another limit reset while reliability work continued. Users still reported weekly caps after long GPT-5.6 Sol coding runs.

OpenAI and Work Louder released kbd-1.0-codex-micro, a compact hardware controller for Codex workflows with mappable buttons, a joystick, status keys, and RGB feedback. Posts from Work Louder and early users describe Codex-focused mappings for multi-agent status, accept/reject actions, six layers, and app auto-switching.

Sam Altman said agentic-product usage rose 2.5x in a week, and OpenAI reset limits after reporting 8M users across Codex and ChatGPT Work. Users also reported slow GPT responses and uneven limit burn.

Posts claimed to publish GPT-5.6 Sol’s Codex Desktop system prompt and tool list, with follow-ups linking full files and highlighting the prompt’s size. The leak is unverified, so the consequence is an alleged security and prompt-injection exposure rather than confirmed vendor behavior.

OpenAI said 7M active users now use Codex and ChatGPT Work, and paid users reported an extra reset card in web and mobile settings. Other reports said GPT-5.6 Sol context changes may reduce Codex burn.

OpenAI said GPT-5.6 Sol's 372k context in Codex charged more usage than intended, so it reverted Codex to 272k. It also removed a five-hour cap, reset some rates, and passed inference savings into more subscription usage.

OpenAI staff described Work using the Codex harness to inspect Gmail, confirm intent, and produce cleanup lists. The rollout also added in-app code editing and a PR tab, while users questioned how Work, Chat, and Codex differ.

Practitioners ran GPT-5.6 Sol through Codex computer control on a five-hour Slay the Spire task and desktop fixes involving Chrome, 1Password, and a custom window utility. One report said Codex queued throwaway scripts for clicks and typing instead of driving every step from screenshots.

OpenAI launched ChatGPT Work, a Codex- and GPT-5.6-powered ChatGPT agent with a desktop app that can access local files and apps. OpenAI staff said Work and Codex use the same sandboxing with UI changes.

Posts say Sol, Terra, and Luna are set for a July 9 launch. One report says Sol was added to the Codex codebase as OpenAI’s strongest model for code, research, and documents.

Codex app code now references GPT-5.6 Sol, Terra, and Luna, while posts claim Sol Ultra reaches 91.9% on TerminalBench at lower cost. Treat release timing, limits, and benchmark claims as unofficial until OpenAI publishes details.

A day after Codex reset limits for weekend drain reports, OpenAI said auto-review, duplicate background suggestions, and retry behavior were compounding usage and issued another full reset. Users also get one extra reset credit within 24 hours while reporting and scheduling fixes roll out.

A day after /goal and thread automations landed in Codex, practitioners started standardizing on /goal specs, /fork or /side detours, and /rewind plus /compact recovery. The pattern matters because verifier design and compaction timing now control how well long runs hold together.

Two days after OpenAI said it had fixed Codex quota drain tied to fraud overflagging, the team opened a Sunday war room for fresh drain reports and issued a hard reset of user limits. The incident matters because background usage and reset rules were still opaque during long-running agent work.

Plannotator v0.21.3 shipped file-scoped comments, a unified review UX, default per-file Ask AI chats, and a more reliable Codex app-server path. It matters because guided reviews and plan checks can now plug into agent workflows with less custom glue.

Codex users documented thread automations as recurring wake-up calls that preserve thread context, alongside /goal and /btw patterns for steering long-running loops. The workflow matters because teams can schedule check-ins, queue instructions mid-run, and add adversarial review passes without building a separate orchestrator.

OpenAI shipped another Codex desktop update with smoother long-thread scrolling, deeper local history, better settings search, and a hover navigation rail. The release matters because long-running sessions keep your place and copy richer Markdown into Slack.

OpenAI said Codex accounts were seeing faster usage draining than intended because abuse and fraud checks were overflagging some sessions, then issued a usage reset for all users. It matters because paid Codex workflows were losing quota unexpectedly mid-run, directly affecting reliability and cost.

OpenAI published usage data showing Codex now generates 99.8% of its internal AI output tokens, with sharp growth in legal, support, recruiting, and finance. The report measures agent adoption as delegated parallel work, not just chat inside engineering.

Codex can now hand off an in-progress thread between local and remote machines and bring it back later. It matters because the handoff carries Git history, branches, and uncommitted changes while leaving the destination checkout untouched.

OpenAI added Record & Replay to Codex so users can demonstrate a repetitive computer task once and save it as a reusable skill. The first rollout is Mac-only and unavailable in the EEA, UK, and Switzerland, so teams should check access before planning rollout.

Codex workflows can now run against open-weight models served through compatible Responses API endpoints, with Ollama and vLLM publishing direct paths for GLM-5.2 and Kimi K2.7 Code. That matters because teams can keep the Codex interface while swapping to self-hosted or lower-cost inference backends.

OpenAI expanded Codex in Europe with Computer Use, the Chrome extension, Memory, and Chronicle. The rollout broadens browser and desktop automation outside the U.S., though some memory features remain opt-in or preview-only.

Codex users are having the agent write its own `/goal` and sub-agent goals, with OpenAI-side commentary describing that as a built-in meta-prompting pattern. The workflow turns long autonomous runs into a tighter control loop, but users still review goals first so a bad objective does not burn tokens for hours.

OpenAI shipped a docs agent that can hand off guides to Codex, and users published Appshots, browser-control, parallel PR, and multi-tree workflows. Watch the examples for ways to structure Codex around orchestrated tasks, while code-review and plugin gaps remain.

AI SDK canary added HarnessAgent, a unified abstraction that runs Claude Code, Codex, and Pi in sandboxed sessions with AI SDK-compatible streams. One integration can now target multiple agent harnesses without separate model-specific plumbing.

OpenAI said it will acquire Ona and fold its secure cloud execution and orchestration stack into Codex. The change targets agent jobs that need to keep running for hours or days after the original laptop session ends.

OpenAI started rolling out bankable Codex resets to Go, Plus, Pro, and Business users, plus a two-week referral program that can add more resets. That lets users save capacity for heavier Browser use and longer Codex sessions instead of losing resets on a fixed clock.

Codex usage moved further into phone-first workflows, with iOS dictation loops, background voice capture, and app updates like searchable settings and restored state. The comparisons still flag rough spots in multi-thread UX, Windows support, and cases where CLI tabs or cloud agents are easier to manage.

A community workflow broke long-running Codex goals into six required fields, then added an eight-item preflight checklist and helper tools. The structure is meant to reduce runs that drift, stop early, or claim completion without an objective verification step.

Helmor released an open-source mobile client that exposes Claude Code, Codex, OpenCode, and custom model backends behind a phone-first UI plus one-click Cloudflare Tunnel setup. The launch targets remote coding sessions from a handset instead of a laptop-only agent workflow.

MagicPath launched as an official Codex plugin, adding a shared canvas for interactive UI work, repo imports, design-system context, and image generation inside Codex. It matters because Codex now has a native surface for design-and-build loops instead of limiting collaboration to chat and code diffs.

OpenAI expanded the Build iOS Apps plugin so Codex can test apps in an in-app browser, open SwiftUI previews, and hot-reload edits without leaving Codex. It matters because more of the iOS iteration loop stays inside the coding agent instead of bouncing through external simulators and manual preview steps.

A day after Codex users reported outages and caps, OpenAI said the service had three separate incidents and later disclosed a bug that undercounted tokens for some Plus and Pro accounts, while users reported paid-plan quotas reset. The update matters because Codex operators saw both service instability and account-limit changes in the same 24-hour window.

Users reported outages, tighter 5-hour caps, and token availability problems a day after OpenAI launched Codex Sites and plugins. OpenAI reset Codex usage limits after three incidents, so teams should watch quotas and backend reliability as agent workflows ramp up.

OpenAI rolled out Codex Sites, annotations, and role-specific plugins, while weekly users topped 5 million. The release pushes Codex beyond coding into hosted workspace and app workflows for enterprise teams.

OpenAI made GPT-5.4, GPT-5.5, and Codex generally available through Amazon Bedrock. AWS shops can now use OpenAI models inside existing IAM, compliance, and procurement workflows instead of adopting a separate vendor stack.
