AI this week: OpenAI's Terra model for everyday computer work

As of October 31, 2026. This week OpenAI put its attention on everyday office work, and Anthropic made news on two fronts: a public filing and a toolkit for nonprofits.

At a glance

iCloud in ChatGPT	Mail and Calendar plugins for iCloud accounts	People who run their business on an iCloud address	Try it: useful if you already live in iCloud, with care on what you connect
Pro usage change	Cancelled cut, higher Work and Codex limits	Heavy ChatGPT Pro users	Watch it: good news, but plans keep shifting
Anthropic S-1	A filing for a proposed public offering	Investors and people who follow the industry	Skip it for now: nothing to act on in your shop

OpenAI releases GPT-6.1 Terra

On October 26, OpenAI released GPT-6.1 Terra, a model built for routine workday tasks such as drafting proposals, reading technical drawings, filling out forms and working across apps on screen. It is available to Plus, Pro, Enterprise and Edu users in ChatGPT Work and Codex, and to developers in the API as gpt-6.1-terra. OpenAI published its pricing and says it is half the price of GPT-5.6 Terra and GPT-6.1 Sol. Its own example is reading incoming invoices and entering them into accounting software. OpenAI says its larger models remain the better choice for the most complex coding work. (OpenAI on X)

For a small business: The invoice example is the one to notice, because that kind of data entry happens in most offices. A lower-cost model makes it easier to try that sort of work on a small scale. Anything it enters into your accounting software should still be checked by a person before it counts.

ChatGPT can now connect to iCloud Mail and Calendar

OpenAI added iCloud Mail and iCloud Calendar plugins to ChatGPT on October 27. Users can ask it to find emails, catch up on their inbox, check their schedule and update calendar events. The plugins are rolling out to all ChatGPT plans on the web, the desktop app and iOS, as described in OpenAI's help article on connected apps. Each is connected separately with an Apple app-specific password rather than your regular Apple password. Mail works only with addresses ending in @icloud.com, @me.com or @mac.com, and both include read-only contact lookup. (ChatGPT on X)

For a small business: Plenty of one-person shops and small family businesses run on an iCloud address. Asking an assistant to summarize the inbox or find a customer's last message could save some time each week. Decide first what mail you are comfortable connecting, and see our one-page AI policy for a starting point.

OpenAI cancels a planned Pro usage cut and raises limits

On October 29, OpenAI said it is increasing the Work and Codex usage included in its Pro and Business Premium plans, according to its release notes. Pro 100 and Pro 500 now include twice their previous Work and Codex allowance. OpenAI also canceled the Pro 200 reduction it had announced in a September 29 email. Subscribers who already had the higher allowance keep it, and those on the lower allowance are doubled to match. Existing subscribers get the change automatically, and OpenAI says the Pro 200 price is unchanged. (post on X)

For a small business: If you pay for one of these plans, you don't need to do anything. It is a reminder that plan limits can change in either direction, so avoid building a daily routine that only works at one particular allowance.

Anthropic files to go public on Nasdaq

On October 26, Anthropic, the company behind Claude, filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission for a proposed initial public offering. It plans to list its Class A shares on the Nasdaq Global Select Market under the symbol ANT. The number of shares and the price range have not been set. The registration is not yet effective, so no shares can be sold until it is. (Anthropic on X)

For a small business: Nothing changes in how you use Claude today. It is useful background on a company many small teams rely on, and we won't read more into it than the filing says.

Anthropic adds a Claude for Nonprofits plugin

Anthropic released a Claude for Nonprofits plugin, built with about 30 nonprofits. It comes installed at no extra cost for verified nonprofits on Claude Team and Enterprise plans. It starts by mapping where an organization keeps its donor data, grant files, finances and policies, and lets staff ask what their own AI policy allows. Fundraising skills research funders and open grants with sources cited, break down an RFP, draft proposals and grant reports from the organization's own material, and prepare funder-call briefs, thank-you notes and donor updates. Anthropic says more than 25,000 nonprofits use Claude, most of them small, local teams, and that it does not train its models on their data by default. (Claude on X)

For a small business: For a New Hampshire nonprofit with a one- or two-person office, grant reports and donor thank-yous are recurring work. Drafts built from your own files can help, but a person should check every figure and every promise to a funder before it goes out.

What this means for a New Hampshire shop

The common thread this week is routine office work: forms, invoices, inboxes, grant reports. Pick one repeating task you can describe in a sentence and try an assistant on it for a few weeks, with someone reviewing each result. If a task involves money or a commitment, the assistant drafts and a person approves.

If you want help choosing that first task and getting your team comfortable with it, our AI cowork training is built for that. Nonprofit offices may also want our post on grant reports for a one-person nonprofit office.
