In the World of AI: Week of 27 October 2026, Copilot Billing Delayed, Gemini 4 Carbon Gated

Microsoft moved the date for pay-as-you-go billing on Copilot Business, Google announced a second Gemini 4 model that almost nobody can use yet, and a Meta survey added to the pile of data on how small businesses use AI. This is the week from 28 October to 3 November 2026, with one step for each story.

1. Microsoft delays default usage-based billing for Copilot Business

Microsoft's Partner Center announcement dated 3 November updates the plan for usage-based billing on Microsoft 365 Copilot Business. It will now be switched on by default for new Copilot Business subscriptions bought through Cloud Solution Provider partners during January to March 2027, instead of 1 December 2026. Some AI experiences, including Copilot Cowork, need usage-based billing and can result in charges beyond the licence fee. Microsoft sets a default spending limit of 4,000 Copilot Credits per user per month, which administrators can adjust. The update lists Australia among the markets where the capability will now be available, after earlier plans had it arriving later in some markets, and says disabling the billing might limit access to AI experiences.

Why it matters: A per-seat licence has a predictable monthly cost, and usage-based charges do not. The default limit is a ceiling per user, so the bill can vary with how much your team uses these features, and you should know it exists before you agree to it.

This week: If you buy or plan to buy Copilot Business through a partner, ask them in writing how usage-based billing will be set up and who sees the spending. Our guide to auditing AI tool seats helps check what you pay for.

2. Meta survey: small businesses see gains and want guidance

IT Brief Australia reported on 28 October on research published by Meta, with fieldwork by YouGov, covering almost 4,000 small business owners across nine markets including Australia. It found 84% use AI, 76% say it has had a positive effect on productivity and 71% say it improved revenue or sales over the past 12 months. Some 86% say small businesses need more guidance, and 51% name the cost of training as the main barrier. The most common uses were content creation or editing (51%), local advertising and marketing (43%), translation (38%), and customer support and communications (37%). The article gives no Australia-only figures, and Meta also promoted its own training programme and advertising tools alongside the findings.

Why it matters: The survey comes from a company that sells advertising, and the results are owners' own reports. Still, the pattern is useful: the commonest uses are everyday communication tasks, not complex projects.

This week: Choose one of those everyday uses, such as drafting customer replies, and agree what a good result looks like before you start. Our answer on how to measure AI return can help.

3. Google announces Gemini 4 Carbon, with limited access

Google's announcement of 28 October introduces Gemini 4 Carbon, a follow-on to Argon. Starting that week it is available to a subset of cyber defenders, with access extended to other trusted partners through the Fairwind Program, and Google is taking part in the US government's voluntary pre-release testing. Google says it will bring Carbon to developers, businesses and consumers "as soon as possible" and gives no fixed date. Introductory pricing matches Argon's, and rises after the introductory period.

Why it matters: Argon only became widely available on 13 October, and Carbon is already announced. Waiting for each new model before acting means waiting forever, since new ones keep arriving.

This week: Choose tools for the problem in front of you, and review the choice once every few months, not every time a new name appears. The good first AI project answer shows how to pick a starting point.

4. Google Workspace adds Gemini features to Docs, Slides and Sheets

Google's Workspace Updates blog lists three AI changes in the last days of October. On 28 October, the Fill with Gemini feature in Sheets began providing cell-level citations for web sources and supports larger requests of up to 3,000 cells. On 29 October, documents, slides, spreadsheets and code can be created, previewed and edited directly in the Gemini app. On 30 October, Gemini in Google Slides can edit an entire presentation from one prompt, with changes that can be undone.

Why it matters: Citations in Sheets make it easier to check where an AI-filled value came from. Whole-deck edits are a time saver and can spread one wrong prompt across every slide.

This week: Before relying on AI-filled spreadsheet cells for pricing or customer data, spot-check a sample against the cited source. The guide on human review for AI output sets out a method.

What to do this week

• Ask your Microsoft partner in writing how usage-based billing will work for Copilot Business.
• Choose one everyday AI use and define what success looks like.
• Skip the rush for new model names and review your tool choices on a schedule.
• Spot-check AI-filled spreadsheet cells against their sources.
