Microsoft is expected to launch Project Perception before the end of this month — an AI-powered tool that scans software for vulnerabilities and suggests fixes, aimed squarely at the enterprise security market currently dominated by Anthropic’s Mythos. The detail that matters for smaller businesses isn’t the vulnerability-scanning itself, though; it’s how Microsoft is pricing it. Project Perception uses a “model router” that sends most tasks to cheaper, faster AI models and only escalates the genuinely hard cases to expensive frontier models — reportedly landing at roughly half the cost of comparable tools. That’s a meaningful shift, and it’s one every UK SME buying or evaluating AI tools should understand, because it’s about to become how a lot of software gets priced.

Why a big-vendor product launch matters to a five-person company

Most UK SMEs will never buy Project Perception directly — it’s built for security teams with existing infrastructure to plug it into. But the pricing model behind it is a preview of what’s coming to the AI tools that smaller businesses do buy: accounting AI, customer service bots, marketing copy generators, and the “AI-powered CFO” and compliance-assistant tools already being marketed at SMEs this year. When vendors can route cheap queries to cheap models and only spend on the hard 5%, the tools should get cheaper and faster for everyone — but only if that saving actually gets passed on rather than pocketed as margin. It’s a fair question to ask any AI vendor pitching you a subscription this year: are you using one model for everything, or are you doing what Microsoft is now doing at scale?

What this means when you’re the one evaluating an AI tool

Don’t be swayed by which underlying model a vendor name-drops — Project Perception itself blends Microsoft’s own models with OpenAI’s and Anthropic’s, picking whichever is cheapest for the job at hand. The output quality and the price you’re actually charged matter more than the brand on the box. When a supplier pitches an “AI security” or “AI compliance” tool, ask three practical questions: what happens to your data once it’s processed, can you see or export what the tool actually found, and what’s the real cost per month once you’re past the free trial or pilot period. Multi-model routing setups can also mean your data touches more than one AI provider behind the scenes — worth asking about explicitly if you handle client data covered by GDPR.

There’s a second, quieter implication worth noting. As routing between models becomes standard practice for the big platforms, price competition on AI tools is likely to intensify rather than settle — which is good news if you’ve been waiting for costs to come down before adopting something, but also means a tool that looks expensive today may not stay that way for long. It’s worth revisiting AI tools you dismissed six months ago on cost grounds; the economics behind them have likely shifted since then, and a subscription that didn’t pencil out in January might well pencil out now.

Watch for the marketing gap between “AI-powered” and actually useful

Not every vendor doing model routing will pass the saving on, and not every “AI-powered” label attached to a product this year reflects a meaningful technical change. Some tools are genuinely getting smarter and cheaper at the same time; others are simply relabelling existing features. The only reliable way to tell the difference is to ask for a trial, test it against a real task from your business rather than a vendor demo, and judge the output on its own merits rather than the pitch.

If you’re trying to work out which AI tools are actually worth adopting for your business rather than just watching the headlines, ApplyAI specifically helps UK SMEs cut through vendor noise and figure out what’s genuinely useful versus what’s expensive theatre. And if you need something built to your specific workflow rather than bought off the shelf, BuildApps can scope a bespoke option and give you a real comparison point against what the big platforms are charging.

The takeaway

Project Perception is a big-company product, but the trend behind it — AI tools getting cheaper through smarter routing between models — is going to show up in the software UK SMEs actually buy this year. When you’re pricing up an AI tool next, ask what’s driving the cost under the hood, not just what the marketing page promises.
