AI is getting cheaper and riskier — three things that hit small business this week
GPT-5.6 drops 50% in price, Copilot Word files can carry hidden instructions, and Firefox rolls out a free AI browser where you pick the model.
Summary
- Prices are falling fast — OpenAI cut GPT-5.6 Sol by 50%, Stripe is buying OpenRouter (one place for 400+ models) for over $7B
- Copilot Word can carry hidden instructions — white-on-white text in documents can make AI execute commands you can’t see
- Firefox is rolling out a free AI browser — you pick the model, chats stay on your machine
Bottom line: AI is getting cheaper and more accessible for a small business — but it also requires a bit of caution with documents from strangers.
1. AI prices keep falling — don’t lock into one vendor long-term
What changed. OpenAI cut GPT-5.6 Sol pricing by 50% — down to $2.50 per million input tokens and $15 per million output tokens (OpenRouter). Meanwhile Stripe agreed to buy OpenRouter for over $7 billion — a service giving 8 million users one entry point to 400+ AI models.
What it means for a small business. If you pay €50/month today for an AI tool that writes emails or handles customer questions, in six months the same quality is likely to be available for €15. But only if you can switch. Example: a small accounting firm that uses AI for client questions can cut its costs by 60-70% over a year — if it isn’t locked into one vendor.
What you can do this week.
- When you pick a new AI tool, check in settings whether you can change the “model” (not just OpenAI, not just Claude). Tools like OpenRouter (from €0, pay per use) or Poe (free plan) let you switch models in one window
- If you pay for ChatGPT Plus (€20/mo) only for text work, try DeepSeek (free) or Google AI Studio (free with limits) — for many tasks the result is comparable
- Don’t sign annual contracts — a monthly plan preserves the option to switch
What to watch.
- Next 6 months: prices likely to fall another 30-50% as OpenAI, Google, Anthropic compete for users
- The Stripe/OpenRouter integration may soon let AI tools bill through your Stripe invoice — easier to budget
2. Copilot Word documents can carry hidden instructions
What changed. Security researchers showed that Microsoft Copilot for Word can be tricked by hidden text (white on white) in a Word document containing instructions for the AI (Malwarebytes). When someone asks Copilot to edit or summarize such a document, the AI executes the hidden instructions and even embeds them into new documents — like a “worm” that spreads across files.
What it means for a small business. If you run a small accounting office or a legal practice using Microsoft 365 Copilot to summarize client-supplied documents — in theory, a stranger’s document can make Copilot leak data from your other files or alter text you later send to a client. Practical example: a client sends over a contract draft, you ask Copilot to summarize it, and the AI carries out hidden instructions that add a misleading clause to your next document.
What you can do this week.
- Don’t run Copilot on documents from people you don’t fully trust — at minimum, open the file first, select all text, set font color to black, and check for hidden text
- If you have Microsoft 365 Business, turn on “Sensitivity Labels” in settings — helps separate internal and external documents
- For critical documents (contracts, finances) read the first summary yourself instead of relying on AI alone
What to watch.
- Microsoft is likely to ship an update in the coming months, but full protection against these attacks isn’t available industry-wide — all major model assistants are similarly vulnerable right now
3. Firefox rolls out a free AI browser — you pick the model
What changed. Mozilla launched Firefox Smart Window — a new browser mode with a built-in AI assistant where the user picks between Google Gemini 2.5 Flash Lite, Alibaba Qwen3, or OpenAI gpt-oss-120B, and chats stay locally on your machine (Verge, OMG Ubuntu).
What it means for a small business. If you use ChatGPT or Claude daily to summarize web pages, draft short reply projects or research information — Firefox Smart Window does the same without a separate subscription and without sending data outside (chats stay on your machine). For a small travel agency or craftsman doing client research online, it can replace a €20/mo ChatGPT Plus subscription.
What you can do this week.
- Download Firefox (free) and after updating to version 150+ enable “Smart Window” in settings (currently available in US, Canada, France, Germany, UK — try with a VPN if you’re outside)
- Summarize 3-5 web pages per day and compare with ChatGPT’s result
- If it’s good enough — cancel your paid AI subscription or keep just one
What to watch.
- Firefox 150 full release in additional markets expected in Autumn 2026
- Other browsers (Vivaldi, Brave) are likely to add similar options with model choice — track which runs fastest on your machine
Today’s picture
Today’s three stories add up to one structural shift — for a small business, AI is getting cheaper and more accessible through free alternatives, but it also requires basic security awareness. Price cuts and aggregators mean you no longer have to “pick a vendor for the year”. Firefox Smart Window means you no longer have to “pay for an assistant”. Copilot vulnerabilities mean you have to know how AI handles incoming files.
| Event | Consequence |
|---|---|
| GPT-5.6 Sol -50% + Stripe buys OpenRouter | Don’t lock into one vendor long-term |
| Copilot Word hidden-prompt attack | Don’t blindly trust AI to process strangers’ documents |
| Firefox Smart Window (free AI browser) | Worth trying before your next €20 subscription |
Three questions:
- Does your AI tool let you change the model in settings, or are you “locked in” to one vendor?
- Is anyone in your office running Copilot on client-supplied Word files without checks?
- How many AI subscriptions are you paying for — and how many are you actually using?
