Google's Gemini 3.5 Flash has become the default artificial intelligence for hundreds of millions of people in recent weeks, often without their knowledge. When you type a question into the Google search bar and a written answer appears at the top of the page, or when you open the Gemini app on your phone, it's now this new model that responds. Google unveiled it at its I/O 2026 conference on May 19th and continued its global rollout in June.

What makes this news significant isn't just the power of the model. It's that it's free, activated by default, and that it no longer simply responds: it can act. For a small business in Trois-Rivières or the Mauricie region, as well as for the general public, this means that a tool capable of coding, conducting multi-step research, or preparing a complete document is now just a click away, without a subscription. Let's see what this changes in practice, and where the potential pitfalls lie.

1. What Google just launched

Gemini 3.5 Flash is part of Google's "Flash" family of processors, designed for speed. The innovation lies in the fact that this version achieves a level of quality comparable to high-end models, while remaining fast and affordable. Google states that the processor is immediately available to billions of people across several of its products.

In practical terms, here's where you already encounter it, often without realizing it:

• The Gemini app on iOS, Android and computer, where it has become the default model worldwide.
• Google Search's AI mode , those written answers that appear above the usual links.
• Thedeveloper interface (Gemini API and Google AI Studio), for companies that want to build their own tools.
• The Gemini Enterprise version , where it was enabled by default at the beginning of June for business accounts.

In terms of performance, Google claims that Gemini 3.5 Flash outperforms the previous generation (Gemini 3.1 Pro) in most of its internal tests, particularly in programming and document comprehension. These figures come directly from the manufacturer: they provide a good indication of the direction, but like any results announced by a company for its own product, they should be taken with caution and validated through your own experience.

2. Why "free and by default" is a game changer

The detail that matters most to the general public isn't the model name, it's the word "free." The Gemini app and Search's AI mode provide access to Gemini 3.5 Flash at no cost, with daily quotas. In other words, the majority of people are now using high-level AI without having chosen it, simply because it's integrated into the Google tools they already use.

For an SME, this has two direct consequences. First, your employees are probably already using it, on their personal phones or in Google, whether or not you have a policy on the matter. Second, the entry cost to testing AI in your operations drops to zero: no more need for a subscription budget to try an assistant capable of summarizing a request for proposals, rewriting an email, or comparing two contracts.

This widespread adoption is good news, provided its use is properly regulated. Free and readily available AI also represents a gateway through which confidential information can leave the company unintentionally. This is precisely the kind of gray area that IT support can help to define, and one of the topics we address in our managed services for SMEs.

3. “Agentics”: AI that acts, not just responds

The key word to remember from this announcement is "agentic." Until now, you asked an AI a question and it answered. An agentic model, however, can independently perform several steps to accomplish a task: search for information, organize it, produce a result, and then correct itself. Google is highlighting Gemini 3.5 Flash's ability to handle long tasks and run multiple agents in parallel.

To give you concrete and realistic examples for an SME:

• Prepare a first draft submission based on a list of requirements and your templates.
• Conduct research on a supplier or competitor and produce a structured summary.
• Sort through an inbox and suggest responses, which you approve before sending.
• Helping a small technical team write or correct code without hiring a full-time specialist.

The important distinction: "acting alone" does not mean "acting unsupervised." An AI executing steps can also make a series of errors. The best practice, especially at the beginning, is to have a human reviewer who reviews and approves everything before anything is sent to a client or a system is modified. Google also announced a more powerful model, the Gemini 3.5 Pro, slated for June 2026: this is just a guideline, as the dates and capabilities of a product not yet deployed are subject to change.

4. What this means in concrete terms for an SME in Quebec

Beyond curiosity, what do you do with all this on Monday morning? Here's a simple way to turn this news into real gains, without turning your business upside down.

Save time on repetitive tasks

The best initial uses are those with low risk and high volume: email drafts, meeting summaries, text rewriting, and note transcription. AI handles the initial drafting, while a human completes the task. The time savings are immediate, and any potential errors have no serious consequences.

To establish a usage policy

Before going any further, write down in black and white what can and should never be entrusted to a free AI: customer numbers, employee files, passwords, personal information. This is also a direct requirement of Quebec's Bill 25, which governs the protection of personal information. One page is enough to start.

Choosing the right tool for the right use

Gemini Free is perfect for exploring and learning. For regular business use involving sensitive data, a professional version with confidentiality guarantees, or an assistant integrated into your office suite, is often a better choice. Making this decision requires comparing several options based on your specific needs, and that's precisely where an IT partner comes in. If you'd like to discuss this for your company, our team can be reached through our contact.

5. Limitations and precautions to keep in mind

No AI, not even the most recent, is perfect. Three points deserve your attention.

• The errors appear plausible. An AI can invent a figure, a date, or a reference with complete confidence. Any data used to make a decision must be verified at the source.
• Privacy depends on the version. What you type into a free tool can be used for purposes you don't control. For company data, read the terms and conditions or choose a professional plan.
• The "default" setting is imposed on you. Since this model is automatically activated in several products, take the time to check where it is active on your device and adjust the settings rather than simply accepting them.

The real skill in 2026 is no longer having access to AI: everyone has that. It's using it methodically, knowing when to trust it and when to keep control.

Frequently Asked Questions

Is Gemini 3.5 Flash really free?

Yes, for everyday use. Google provides free access to Gemini 3.5 Flash within the Gemini app and in AI-powered Search, with daily quotas. Paid versions are available for more intensive or professional needs.

What is the difference between this and ChatGPT or Copilot?

These are competing AI assistants. Gemini is Google's offering, integrated with Search and its applications; ChatGPT comes from OpenAI; Copilot is Microsoft's assistant integrated with Windows and Microsoft 365. The best choice depends on the tools your SME already uses.

Can I use it with my clients' data?

Not in the free version, as a precaution. For personal or confidential information, you need a professional service with confidentiality guarantees and compliance with Law 25. Have your case reviewed by a specialist before disclosing sensitive data.

Adopting AI without putting your business at risk

Gemini 3.5 Flash highlights a fundamental trend: powerful AI is becoming free, available by default, and capable of taking action. This presents a real opportunity to save time, provided you establish clear rules and choose the right tools for the right tasks.
