Gemini's big headline is Gemini 4 Argon, announced on 30 September, but it is restricted to select cybersecurity partners and, Google says, will reach AI Ultra subscribers first. The features most UK businesses can actually use are Connected Apps, Notebook tools, Magic Pointer and Rambler, plus new effort levels.
What matters for a UK business: from 9 October the free Gemini app drops to Flash-Lite, and AI Plus loses Pro. If your team relies on a free account, check what they can still reach. Gemini remains the natural choice if you work in Google Workspace.
What has Gemini launched in the last month?
Google's announcements are spread across the Gemini app, Workspace and Gemini Enterprise, which makes them easy to miss. Dates are 2026. Where Google gave a month rather than a day, the table says so.
| Date | New feature | What it does | Who gets it |
|---|---|---|---|
| 9 Oct | New model limits in the Gemini app | Free users limited to Flash-Lite; AI Plus gets Flash-Lite and Flash; AI Pro gains Deep Think | Free, AI Plus, AI Pro |
| 6 Oct | Nano Banana 2.1 generally available | Faster image generation and conversational editing with better text rendering | Gemini API |
| 6 Oct | Antigravity admin controls | Admins manage access to Boost and Teamwork features | Gemini Enterprise |
| 2 Oct | Skills in Gemini and Workspace updates | More natural Vids voiceovers, customisable captions, Docs and Meet changes | Google Workspace |
| 30 Sep | Gemini 4 Argon | Google's new flagship, aimed at coding, legal, finance and cyber defence work | Select cyber partners; Ultra first |
| Sep | Connected Apps | Gemini can work across your other apps to finish tasks | Gemini app |
| Sep | Notebook tools | Study and research tools built around your own notes and sources | Gemini app |
| Sep | Magic Pointer and Rambler | Point at anything on screen and ask; voice brain dumps become organised notes | On-device |
| Sep | Gemini 3.8 Flash Cyber | Vulnerability discovery and patching for defenders | Trusted organisations via Fairwind |
The new Gemini features that matter most
Gemini 4 Argon: the model you cannot have yet
Google says Argon is its most performant model, comparable to OpenAI's Astra and Anthropic's Opus on key coding and cyber benchmarks. It was released first to select cybersecurity partners, with guardrails removed for defenders. Google's own benchmark table has it winning or tying in 13 of 18 categories. That is the vendor's table, and one analyst's reading is that the frontier did not collapse into one winner. For now, Argon is news, not a tool.
New limits and effort levels in the Gemini app
From 9 October, people without a Google AI plan can use only Flash-Lite. AI Plus subscribers get Flash-Lite and Flash but not Pro. AI Pro and Ultra keep everything, and the $19.99 a month Pro tier gets the Deep Think option. 9to5Google also reports low, medium and high effort levels coming for each model, which will trade depth against how fast you burn your allowance.
Connected Apps
Connected Apps lets Gemini carry out tasks across the apps you already use. This is Google's answer to the agent race, and for a Workspace business it is the feature to watch.
Magic Pointer and Rambler
Wiggle your cursor and ask Gemini about whatever is on your screen. Dictate a messy brain dump and Rambler turns it into structured notes you can share. Both are on-device features and neither needs a prompt. Frankly, they are the two most human ideas in the update.
Notebook tools
New Notebook tools sharpen the study and research side of Gemini, building on the NotebookLM approach of working from your own sources. Useful for staff who need to learn a regulation or a product range quickly.
What is good about the new Gemini features?
- Lives inside Google Workspace. If your firm uses Gmail, Docs, Sheets and Meet, there is less to set up.
- Useful everyday touches. Magic Pointer and Rambler save small amounts of time many times a day.
- Strong with images and audio. Nano Banana 2.1 and the new voice models are good for marketing assets.
- A clear plan ladder. You can see what each tier gets, including Deep Think on AI Pro.
- Enterprise controls are growing. Admin switches for Antigravity features and model access help IT teams.
What is not so good?
- The flagship is not available. Argon is restricted, so the headline model does nothing for most people this month.
- Free users lose ground. From 9 October the free app is Flash-Lite only, which is a visible downgrade.
- Branding is confusing. Gemini, Gemini Enterprise, Workspace, Antigravity and NotebookLM overlap, and features land in different places.
- Several features are vague. Google has described Connected Apps and Notebook tools in broad terms, so test before you plan around them.
Is Gemini best in class, and for what?
Gemini is best in class for Google Workspace users, multimodal work (images, audio and video) and anything where the work already lives in a Google account. It is the sensible default for a firm that never touched Microsoft 365.
It is not where I would send a nervous team for polished writing or sourced research. Claude and Perplexity are stronger there. Our Gemini for Dummies guide covers the basics.
Where should UK businesses use Gemini?
Gemini fits UK firms on Google Workspace and anyone who wants quick help with images, audio and notes.
| Task | Use Gemini? | Why |
|---|---|---|
| Drafting and summarising in Gmail, Docs and Meet | Yes | Native to the Google apps your team already uses |
| Voice notes into organised summaries | Yes | Rambler does this on-device |
| Marketing images and edits | Yes | Nano Banana 2.1 is strong on text and character consistency |
| Learning a regulation or product range | Yes | Notebook tools work from your own sources |
| Free-account use by staff | Check first | Free now means Flash-Lite only |
| Frontier coding or cyber work | Not yet | Argon is restricted to select partners |
| Sourced, citation-heavy research | No | Perplexity is built for this |
Where to be careful
- Free accounts at work. Staff using a personal free account are on the weakest model and outside your data controls.
- Region and plan. Check what your Workspace or Gemini Enterprise tier includes before you promise a feature.
- Vendor claims. Treat Google's benchmark wins as marketing until independent tests arrive.
A sensible first test
Open Gemini, talk for two minutes about the week ahead using Rambler, and see if the structured notes match what you meant. Then use Magic Pointer on a messy spreadsheet and ask it to explain the odd column. Ten minutes will tell you if it fits.
Learn it properly, on your own work

Frequently asked questions about Gemini
What are the new features of Gemini in October 2026?
The main ones are Gemini 4 Argon (restricted access), Connected Apps, Notebook tools, Magic Pointer, Rambler, Nano Banana 2.1 image generation, and new model limits on the free and AI Plus plans from 9 October.
What is Gemini 4 Argon?
Argon is Google's new top-tier model, announced on 30 September 2026 and aimed at coding, legal, finance and cyber defence. It is available only to select cybersecurity partners, and Google has said AI Ultra subscribers get it first.
Can I use Gemini 4 Argon today?
Not in the normal Gemini app. Google has said access starts with select cyber partners and AI Ultra subscribers, so most people cannot use it yet.
What changes for free Gemini users on 9 October?
People without a Google AI plan are limited to the Flash-Lite model and lose access to Flash and Pro. AI Plus keeps Flash-Lite and Flash. AI Pro and Ultra see no cuts.
What are Magic Pointer and Rambler?
Magic Pointer lets you wiggle your cursor and ask Gemini about anything on screen. Rambler is smart voice dictation that turns a spoken brain dump into organised, shareable notes.
Is Gemini better than ChatGPT for UK businesses?
If you run on Google Workspace, Gemini fits better. ChatGPT has a broader consumer toolbox. Try both on real tasks, and use the same data rules for each.
Is Gemini safe for business data?
Workspace and Gemini Enterprise plans have business data controls that free personal accounts do not. Use a managed account for work and write a short AI policy.
