ChatGPT

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.

OpenAI expanded Lockdown Mode from organizations to personal and self-serve Business accounts, adding an opt-in setting that limits outbound network requests. The feature is meant to block the final exfiltration step in prompt-injection attacks, though malicious instructions can still affect responses.

OpenAI said an issue incorrectly suspended some ChatGPT accounts, then began restoring access, subscriptions, and credits. Users who were locked out should check account status and verify service access before resuming work.

OpenAI rolled out a more capable ChatGPT memory system that keeps context across conversations, shows a reviewable memory summary, and doubles memory for US Plus and Pro users. The change matters because persistent context becomes a first-class product feature with explicit controls instead of a static saved-memories note list.

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 restored Codex weekly and hourly quotas across paid ChatGPT plans after Tibo Sottiaux said the product hit 5 million users. Watch for long-running QA loops, migration PRs, and remote desktop sessions that can still burn through quotas fast.

Codex on iOS now supports side conversations, end-of-turn diff summaries, archived remote threads, model switching, and Spotlight or Shortcuts hooks. The update brings more desktop-style task steering and change review to mobile sessions.

OpenAI added computer use to Codex on Windows and lets ChatGPT mobile steer tasks running on Windows PCs. The update extends Codex to existing Windows dev machines and adds remote review and debugging from mobile.

OpenAI rolled a new GPT-5.5 Instant into ChatGPT and the API with less bullet-heavy output, better pacing, and higher multilingual quality. The update also replaces Canvas in GPT-5.5 Instant and Thinking with in-chat writing and code blocks, so users should migrate workflows while legacy models still keep Canvas temporarily.

OpenAI said the API and ChatGPT were seeing elevated latencies before marking the incident resolved later in the day. User reports showed stalled GPT-5.5 sessions and retry loops, turning the issue into a production and coding-agent disruption.

OpenAI said ChatGPT, Codex, and the Responses API can reach private MCP servers over outbound-only HTTPS without inbound exposure. The same enterprise update adds workload identity federation plus admin controls for spend alerts, allowlists, retention, and hosted tools.

OpenAI documented Codex remote connections, letting the ChatGPT app point at a separate Codex host such as a Mac mini or rented VPS. Try it for long runs that need to stay alive off-device or for phone-first coding sessions.

Days after `/goal` workflows first surfaced, users showed the command also works in the Codex app and shared runs for SSH setup, mech-interp scripts, and recurring work that lasted hours or days. The evidence points to Codex being used as a long-running research and ops agent, though the app still lacks explicit `/goal` UI.

Zed users can now sign in with a ChatGPT subscription and use the same OpenAI limits they get in Codex, alongside ACP, Codex CLI, or API-key flows. It removes a separate billing step for teams switching between editor-native and Codex-native workflows.

OpenAI rolled out Codex in the ChatGPT mobile app, letting users start work, review outputs, approve steps, and steer remote sessions from iPhone or Android. The preview keeps execution on a laptop, Mac mini, devbox, or SSH target while syncing screenshots, diffs, and terminal state back to mobile.

Posts and screenshots from TestingCatalog, Kolt Regaskes, and others say Codex remote access is being prepared inside the ChatGPT app, but OpenAI has not confirmed a release. If real, the feature would extend the recent remote-control push from desktop sessions to phones.

OpenAI is rolling GPT-5.5 Instant into ChatGPT as the default model and exposing it as gpt-5.5-chat-latest, alongside Memory Sources for personalized replies. The model also claims 52.5% fewer high-stakes hallucinations, so watch for behavior changes in production prompts.

OpenClaw now lets users sign in with a ChatGPT account and use an existing subscription inside the harness. That gives teams a sanctioned access path for third-party agent workflows just as Claude Code users report tighter billing and refusal heuristics elsewhere.

OpenAI added an opt-in security mode for ChatGPT and Codex that disables password-based recovery, shortens sessions, and requires passkeys or physical keys. Higher-risk accounts get stronger phishing resistance and automatic exclusion from model training when the mode is enabled.

OpenAI rolled out GPT-5.5 and GPT-5.5 Pro in ChatGPT and Codex, with higher scores on terminal, OS, cyber, and math evals than GPT-5.4. Codex also gained browser, document, and computer-use features for longer agent workflows.

OpenAI introduced shared workspace agents in ChatGPT for Business, Enterprise, Edu, and Teachers plans, with Codex-powered background work across tools like Slack and Linear. The launch turns ChatGPT from a single-session assistant into a long-running team workflow surface with approvals, scheduling, and shared context.

OpenAI introduced a free ChatGPT tier for verified U.S. clinicians and released HealthBench Professional, an open benchmark built from real clinical chat tasks. The launch pairs a clinician-facing workflow product with a public evaluation set and published model results.

A day after GPT Image 2 launched, developers and tool vendors posted reproducible workflows for floor plans, QR codes, conference posters, typography, and Figma-style asset generation. The follow-up matters because it shows where text-heavy visual generation is already usable, but also that quality depends heavily on mode choice, image size, and surrounding tool scaffolding.

OpenAI shipped a Google Sheets add-on that lets ChatGPT build, edit, analyze, and update spreadsheets with natural-language prompts. The integration gives teams a lightweight way to automate sheet workflows without moving data into a separate BI or scripting stack.

OpenAI released GPT Image 2 in ChatGPT, Codex, and the API with thinking mode and 2K outputs. Early tests and Arena scores suggest it is usable for slides, UI mockups, and dense infographic layouts.

Multiple Pro users said GPT-5.4 Pro started producing richer front-end and SVG outputs with much faster runtimes, despite no formal OpenAI announcement. The reports matter because they affect whether long visual and code-generation tasks are practical inside ChatGPT.

Fresh hands-on reports show Codex controlling minimized apps via macOS APIs, using a DOM-aware browser comment mode, and running for day-long sessions in the desktop app. That gives OpenAI stronger evidence that computer use is usable for daily development, though the rollout remains macOS-first and brittle around working-state changes.

OpenAI launched GPT-Rosalind for biology, drug discovery, and translational medicine, plus a life sciences plugin for Codex. Access starts as a trusted preview for qualified customers, so near-term use is limited to partner and enterprise workflows.

OpenAI said a compromised third-party developer tool affected its macOS app-signing workflow and is rotating certificates for ChatGPT Desktop, the Codex app, Codex CLI, and Atlas. The company said it found no evidence of user-data access or software tampering, and older macOS app versions will stop working after the update window.

OpenAI added a $100 ChatGPT Pro tier with 5x more Codex usage than Plus and kept the $200 tier as the highest-capacity option. The new tier resets Codex limits again and temporarily doubles Pro usage through May 31.

OpenAI said Codex reached 3 million weekly users and reset usage limits, with another reset planned for each additional million users up to 10 million. ChatGPT-sign-in Codex will also retire the gpt-5.2 and gpt-5.1-era lineup on April 14, so teams should watch for model-default changes.

OpenAI rolled out Codex-only seats with pay-as-you-go pricing for ChatGPT Business and Enterprise instead of fixed bundled access. The change lowers pilot friction for teams and ties spend directly to coding usage rather than a full ChatGPT seat.

ChatGPT now saves uploaded and generated files into an account-level Library that can be reused across conversations from the web sidebar or recent-files picker. It removes repetitive re-uploading and makes past PDFs, spreadsheets, and images part of a persistent working context.
