OpenAI reset usage limits for all Codex and ChatGPT Work users after a near-global outage in the early hours of the morning.
OpenAI is reinstating the 5-hour rolling window on Plus accounts for ChatGPT Work and Codex, to smooth compute load and stop newer users burning a full week of quota in a single session. Pro $100 and Pro $200 subscriptions stay exempt for the upcoming months.
OpenAI has started releasing GPT-6 Astra in stages over several days while new serving infrastructure comes online. Plus users are included alongside Pro, Business and Enterprise. The post gives no capability or pricing details, and the linked release page could not be read.
OpenAI put its Decisions API into public beta for all developers. It is a realtime classifier for choosing the right model, tool, or action, with a claimed speedup of up to 10x over GPT-6 Luna via the Responses API.
OpenAI's Codex lead documents how to enable a 1M-token context window for GPT-5.6 Sol: three config.toml settings (model, context window, auto-compaction threshold) and a one-session CLI override. It also now works with ChatGPT account usage, with a caveat about the tuned default.
OpenAI resets paid Codex and ChatGPT Work usage and itemizes the bugs that drained allowances: stale images through compaction, Stop-hook-trapped memory workers, /goal overruns, over-frequent automations, subagent escalation, repeated Computer History summarization, and MCP double encoding.
OpenAI announced ChatGPT Space, collaborative rich notes with live visualizations that people and agents edit together and that agents keep updated in the background, pitched as AGENTS.md taken further.
OpenAI's Tibo Sottiaux spells out how Codex subscription multipliers are metered: the Pro tier's 20X is a weekly quota multiple of Plus, and neither Codex Pro plan enforces a rolling five-hour cap. Relevant context if you are comparing coding-agent plans on throughput.
OpenAI's Codex team re-shipped Codex cloud, and Tailscale announced Codex Cloud can now securely connect to resources on a tailnet, opening private infrastructure to cloud coding agents.
OpenAI traces faster Codex quota drain to specific causes: degraded prompt-cache hit rates, inefficiency with images in long sessions that compact repeatedly, high p95 Computer History usage, and a conversation-title feature burning more than intended. Fixes shipped alongside a full reset for paid p
OpenAI adds a team-oriented tier alongside the $100 Pro plan: full Codex and ChatGPT Work access, Workspace/Slack/GitHub/M365 connectors, SAML SSO and MFA, centralized billing, usage analytics and spend controls, and no five-hour limit.
OpenAI is pausing new sign-ups for its $200/month Pro plan, which grants access to GPT-6 Astra, due to system strain, while leaving other plans, the API, and existing Pro accounts untouched.
OpenAI consolidated API usage tiers from five to three: Build, Launch, and Grow. The new top tier, Grow, requires $500 in total API payments, down from $1,000 for the prior highest tier, easing access to higher rate limits.
OpenAI relaunched Codex Cloud with configurable cloud environments and put the Agents API, which powers its cloud agents including dots and supports computer use, into preview.
OpenAI released GPT-6 Sol and Luna with broad quality gains and a permanent 50% cut to API pricing, plus a one-time banked usage reset for Plus, Pro, and Business subscribers.
OpenAI's dots are 24/7 agents with their own computer and browser, powered by Astra and connected to over 4,000 apps. A primary dot is included in Pro without drawing usage, with multi-dot teams coming.
Terra returns as a new model said to write better, follow nuanced requests more accurately, and handle computer use well. The post claims it gives 2X more usage than 6.1 Sol across API and subscriptions. No benchmarks accompany the claim.
OpenAI's Codex lead explains that Pro $200 reopens with usage calculation netting out at half the prior API dollar value, no 5-hour limit, and GPT-6 Sol and Luna API prices cut 50%.
OpenAI opened its Agents API, the same Codex-harness infrastructure behind ChatGPT Work, letting developers spin up scaled cloud agents with custom tools and sandboxes in under a minute.
OpenAI is ending its partnership with Cursor and cutting off model access on November 12, citing trust. Own-API-key usage and OpenAI's IDE extensions remain supported paths, and the company says it will keep working with other harnesses.
OpenAI previews Private Safety Processing: for Zero Data Retention customers, safety pattern-matching runs on infrastructure the customer controls and returns only limited signals, leaving prompts and responses unexposed to OpenAI employees. A hosted option with customer-controlled keys starts rolli
An argument that a token is not a standard unit: identical text costs different token counts on different tokenizers, so a cheaper per-token price can still produce a larger bill. One sample measured 766 tokens on GPT-5.6 Sol against roughly 1,170 for Claude Opus 5. Vendor-authored, so verify on you
OpenAI is retiring GPT-5.3-Codex-Spark next week due to declining usage, pushing Codex users toward newer models.
A Codex postmortem on destructive deletes: cleanup routines reused variables like $HOME and could target the real home directory, and temp paths were overwritten without checking contents. Fixes span explicit model instructions, execution-layer detection of high-risk delete commands, and making Full
