The AI Productivity Weekly: Saturday 31 October 2026
GPT-6.1 Terra, Gemini 4 Carbon, Copilot Fusion, file editing in Gemini and up to $500 a month in OpenAI API credits.
This Week in One Minute
Welcome to Edition 3 of The AI Productivity Weekly, a short Saturday roundup of the AI news that changes how you work.
The theme: AI work is getting cheaper to run and easier to account for. Cheaper computer-use models, model routers and new spending reports all arrived this week. This edition covers news from Sunday, Oct 25 through Friday, Oct 30. All dates are in UTC.
1. OpenAI releases GPT-6.1 Terra, a cheaper model for computer use
GPT-6.1 Terra combines image understanding, computer use and plainer writing. It is rolling out in ChatGPT Work and Codex on Plus, Pro, Business, Enterprise and Edu plans. In the API, gpt-6.1-terra costs $1 per million input tokens and $5 per million output tokens, which OpenAI says is 50% less than GPT-5.6 Terra and GPT-6.1 Sol.
Why it matters for your productivity: routine screen work, like entering invoice details into accounting software, gets cheaper to hand off.
2. Google previews Gemini 4 Carbon, starting with cyber defenders
Google calls Carbon its strongest model, built for long-running coding and cybersecurity work, ranking first on the Artificial Analysis Intelligence Index v5.0 with a score of 59. Access starts with a subset of cyber defenders through Google’s Fairwind Program; developers, businesses and consumers get it later, with no date yet. The introductory price matches Argon at $2 per million input tokens and $10 per million output tokens, rising to $4 and $20 afterwards.
Why it matters for your productivity: you can budget for Carbon now, but don’t plan work around it until access opens.
3. GitHub’s Copilot Fusion picks the models for each coding task
At GitHub Universe, Microsoft-owned GitHub launched Copilot Fusion, a router on all Copilot plans that uses one model per request or has one draft while others review. GitHub says Fusion Max scored within two points of Claude Opus 5.5 Max on the Artificial Analysis Coding Agent Index at half the cost and 40% less time per task. GitHub Enterprise customers can use every Copilot feature without a separate subscription, paying for the AI credits they use.
Why it matters for your productivity: one setting replaces picking a model for every task.
4. The Gemini app now creates and edits files right in the chat
Gemini can now generate documents, PDFs, slide decks, spreadsheets, Markdown and code, show a preview in the chat, and let you edit directly or highlight a section for Gemini to revise. PDF editing works on web and mobile; the other formats are web-only for now. It’s available to all Gemini app users, in every language the app supports.
Why it matters for your productivity: you can fix a first-draft deck or tracker in one place before opening it in Slides or Sheets.
5. OpenAI adds up to $500 a month in API credits to Pro and Business plans
Eligible Pro subscribers can claim $100, $200 or $500 a month in API credits, matching their Pro tier. Business workspaces get $20 per paid Standard seat and $100 per paid Premium seat, pooled and capped at $500 a month. Credits go to one linked API organization, expire at the end of each billing cycle, and do not increase signed-in Codex or ChatGPT Work usage or cover Codex through API keys. On Oct 29, OpenAI also doubled the Work and Codex allowance on Pro 100 and Pro 500, canceled a planned Pro 200 reduction (and raised lower-allowance Pro 200 to the higher limit), and increased Work and Codex on Business Premium.
Why it matters for your productivity: if you already pay for Pro or Business, you can build a small internal tool or agent without a new budget line.
6. Claude Enterprise adds smart reports and pooled team budgets
Smart reports analyze a sample of a team’s Claude transcripts, group the work into workstreams, and show spend, friction points and workflows worth turning into skills. Pooled group budgets give each team one shared budget; both, plus in-app surveys, are generally available for Claude Enterprise. On Oct 29, Anthropic also released a beta Usage and Cost Analytics API broken down by model, workspace, API key and user.
Why it matters for your productivity: leaders can see which AI work pays off before adding seats or budget.
7. Notion Agent now makes Office files and labels its own edits
Notion Agent can now use a computer to create and edit files, turning a conversation into a finished Excel spreadsheet, Word document, PowerPoint deck or PDF without leaving Notion. On Oct 29, Notion’s “Last edited by” label started showing which agent, MCP client or automation made a change.
Why it matters for your productivity: deliverables arrive in the format clients expect, and bot edits are easy to spot.
8. Perplexity’s voice mode can now steer several Computer tasks at once
Perplexity’s updated voice mode lets you work across multiple Computer sessions, start new tasks, and create and manage Projects in one spoken session. It runs on OpenAI’s gpt-live-1 and is available now in the Mac app and on the web for Pro and Max subscribers.
Why it matters for your productivity: you can redirect parallel jobs by talking, without switching windows.
Also This Week
- Oct 27: ChatGPT added iCloud Mail and Calendar plugins on all plans, on web, desktop and iOS.
- Oct 27: Grok Bot 0.78.1 added templates that find subscriptions you still pay for and cancel the ones you pick, or watch renewal prices; Bots confirm with you before changing anything.
- Oct 27: n8n 3.0 entered beta with safer defaults and breaking changes; the in-app Migration Report lists which workflows need updates.
Tool to Try This Week: Edit Markdown Files in Google Docs
Since Oct 26, Google Docs and Drive handle Markdown natively for anyone with a Google or Workspace account. Upload one non-sensitive .md file, such as a README or an AI-written draft, to Drive, then open it in Docs and add a comment. The file stays .md (look for the badge in the header), and version history records every change by people and agents.
What to Watch Next Week
- Nov 3–6: Snowflake Expedition, a global virtual event, promises data and AI agent announcements.
- Any day: wider access to Gemini 4 Carbon; Google says developers, businesses and consumers get it “as soon as possible.”
- Through Nov 30: GitHub is offering 30% off Copilot Fusion model costs on paid plans, a cheap way to compare it with your current model.
- Early December: n8n 3.0 goes stable; check the Migration Report in your instance before then.
That’s Edition 3. If one item here saves you an hour next week, forward it to the teammate who’d use it too, and come back next Saturday for Edition 4.
