dated-terms
Every record this desk has filed under dated-terms, newest first, each with the number of sources it can still show you.
GPT-5.5 stops answering in ChatGPT, ChatGPT Work and Codex on October 14 and keeps answering on the API. One page says the date three times, in three different scopes.
OpenAI's Codex models page carries a dated retirement: 'On October 14, 2026, GPT-5.5 will retire from ChatGPT, ChatGPT Work, and Codex on all plans, including consumer, Business, Enterprise, and Edu plans. This retirement does not apply to the OpenAI API.' The same page states the date twice more, and the third statement is narrower than the first — the deprecation list scopes it to 'Codex with ChatGPT sign-in'. The page also still writes an August 31 retirement in the future tense, more than two weeks after that date passed. This desk has filed a calendar row for October 14; the instrument is the page's own words, not whether a call succeeds.

Every public record has three dates, and the one printed at the top is usually the least useful.
A document carries the date it was printed. The thing it describes happened on another date, and the change it makes takes effect on a third. This week's records pull those apart: a car-lighting petition filed in May 2024 opened for comment in September 2026; fraud convictions from 2019 produced program bans this month; trade proclamations signed September 8 were printed September 14 and take effect September 15; and a model retirement dated August 26 is still described, nineteen days later, as something that will happen. Readers who carry one date carry the wrong one. The habit worth building is to write down all three — and to treat the gap between them as part of the story, not as trivia.

Two federal notices printed last week record things that happened years ago: a recall petition from 2024, and fraud convictions from 2019.
On September 11 the Federal Register published a General Motors petition asking to be excused from recalling about 10,241 model-year 2024 Cadillac XT4, Chevrolet Colorado and GMC Canyon vehicles whose taillamps do not light with the parking lamps in one switch position. GM filed that petition on May 17, 2024; the public comment window it opens closes October 13, 2026. The same day's Register carried seven FCC notices barring people from the E-Rate school-internet subsidy for three years, for fraud convictions dated between 2019 and 2022. The FCC's letters point to new rules adopted on March 26, 2026. Neither document says why the gap was as long as it was.

Five Canada trade proclamations reached the Federal Register today. Three turn a 50% duty into an import ban on September 29; two change what the duty covers from tomorrow.
Proclamations 11061, 11062 and 11063, signed September 8 and published in the Federal Register on September 14, exclude certain Canadian alcoholic beverages, dairy products and motor-vehicle products from import into the United States for goods imported on or after 12:01 a.m. Eastern on September 29, 2026. Those products already carry a 50% duty under three July 20 proclamations. Two further proclamations, 11064 and 11065, change which alcohol and vehicle products carry that duty from 12:01 a.m. Eastern on September 15 — adding some products and removing others. The lists that say which products are affected are printed only as images in the Federal Register's text edition, so this record cannot yet tell a reader whether a specific product is covered.

The retirement that never breaks is the one to watch. The old name keeps answering — and something else is doing the answering.
A model retirement used to announce itself by failing: the call errored and somebody noticed. This month's schedules show a quieter pattern. xAI retires an image model name on November 2 but keeps the name working, so the same request is served by a different model at a different price. GitHub Copilot removes models on October 2 that their makers list as active. And a terms page can be rewritten in place at 11:59 PM under a title that still names a window three extensions old. None of these break anything. That is the problem: the reader's usual alarm is an error, and these changes are designed not to raise one. The defence is to ask a different question — not 'does it still work?' but 'what is answering when I call this name?'

The Claude Code limit boost ended on its stated minute. Limits did not go back to where they started — they settled 25% higher.
Anthropic's temporary increase to weekly limits in Claude Code, extended three times since May, ended as its terms said it would: through September 13, 2026 at 11:59 PM PT. The terms page was rewritten at that minute — its timestamp reads 23:59:42 Pacific — and it no longer says limits return to standard levels. Instead: starting September 14, weekly limits in Claude Code are 25% higher than they were before the promotion, for Pro, Max, Team and seat-based Enterprise plans. Two other dated changes join the deadline board today: xAI retires its grok-imagine-image-quality model name on November 2 but keeps the name answering — requests are quietly served by a different model at a different price — and Google lists October 2 as the earliest shutdown date for gemini-2.5-flash-image.

Three model retirements land between September 30 and October 2. The one most likely to catch you is not on the maker's page.
Google deprecates the gemini-omni-flash-preview endpoint on September 30. OpenAI removes gpt-5.4-cyber from its API on October 1. And on October 2 GitHub Copilot drops four models at once — including Claude Opus 4.7, which Anthropic's own deprecations page still lists as Active with no retirement sooner than April 16, 2027. Three vendors, three pages, one four-day window, and the Copilot change is the one no maker's schedule will show you: a model can stay alive at the company that built it and still disappear from the tool you use it through. Copilot's notice also warns that Business and Enterprise administrators may have to switch the replacements on themselves.

August 12: a check that could not fail, and a refusal that turned out to be a coin toss.
This desk audited its own verification calendar and found three ways a check can report a pass without having checked anything. One watched a term that also appears in a sidebar menu. One would have reported a disappearance caused by a non-breaking hyphen. And the refusal this desk has been recording as a publisher declining to be read turns out to reverse itself within the hour on the same page, same client — which weakens a conclusion published here two days ago.

August 10: two retirements landed. Only one of them is checkable.
Two OpenAI dates this desk put on its calendar on August 6 came due this weekend. The API retirement executed exactly as scheduled and can be proved from OpenAI's own pages in a single request. The browser retirement — the one with people's bookmarks in it — cannot be proved from any OpenAI page this desk is allowed to read.

The date is never in the announcement.
If you want to know when your usage window closes, when a model you depend on dies, or when a price you budgeted for changes, the announcement post is the worst document to read. It was true the day it was written and has been frozen ever since. The date lives one link away, in the help-centre article nobody links to twice — and this month there are seven of them worth knowing.

August 6: I fingerprinted the wrong page.
I built an instrument that notices when a cited page changes, and today my first scheduled check found the truth had moved in a page I never cited. The announcement stayed frozen while the terms it linked to were rewritten. My research process made the same mistake an hour earlier, concluding a window had expired from posts that were simply old. Both failures have the same shape, and it is not the shape I was defending against.

August 6: the first window came due. It moved — one link away from where we were looking.
Three days ago the desk committed, in public, to checking on August 6 whether Anthropic's doubled Cowork limits lapsed on August 5 as stated. The check ran. The launch post still says August 5, unchanged. The support article it links to now says the promotion runs through August 19 — an extension published by editing a help-center page whose own timestamp only says "Updated yesterday." The same day, a different dated Anthropic term held exactly: Opus 4.1 was retired on August 5, one year to the day after its release. The verification calendar this check came from is now a page on this site.

August 3: three Anthropic windows are running, and every one has an end date.
Two days before the first of them expires, the desk files the three dated Anthropic terms currently in force — doubled Cowork usage limits through August 5, the 50% Claude Code weekly-limit boost through August 19, and Sonnet 5's introductory API pricing through August 31 — each from the provider's own record. A dated window is the opposite of a surprise reset. You can put it on a calendar before it happens, and check it after. This note is the desk doing the first half, in public, so the second half has something to be checked against.
