AI: The Future Is Hybrid – Once Again

When I (Pavol) was still working for a global corporation, the cloud arrived in a big way. If you believed the major providers, the future was what we today call "cloud only": all workloads, data, and compute power move to the cloud, and customers get their IT straight out of the socket. No on-site IT know-how needed, no security risks – the big provider takes care of everything.

And with it, no local value creation either, since the IT guys in fleece jackets would never be needed again.

Even back then, my colleagues and I pushed back: the cloud will never disappear, but it will also never be the only option. There will always be situations where local IT makes sense – for many reasons: personnel data protection, intellectual property, geopolitics, compliance, or simply the good old avoidance of network outages.

We were right. Today, companies have – and use – many ways to shape their IT. The term "private cloud," an oxymoron back then, is now common practice.

Now, in 2026, we find ourselves facing AI.

I won't go into detail on why and what it's good for – the answer is "for many reasons, and for almost everything." And the discussion starts all over again: will we knowledge workers be replaced by abstract algorithms running in massive data centers hundreds of kilometers away – and will data sovereignty be given up in the process?

I'll allow myself a prediction: no, that won't happen. There will be good reasons to use hyperscaler services, but equally good reasons to run local LLMs. These reasons resemble the ones from the cloud dilemma 15 years ago.

What Local AI Is Good For

1. Data protection and sovereignty

   Sensitive data (HR, finance, contracts) belongs in local systems. Here, companies retain full control – a decisive factor, especially in Europe. It's not a matter of preference but a compliance issue. Auditable AI? That's only possible locally, or "private."

2. Cost control

   Not every request needs an expensive top-tier model. Routine tasks can be handled locally, while complex questions go to the cloud. The result: better scaling at controlled costs. Have your developers already burned through their tokens by mid-morning? Then you know what we're talking about.

3. Flexibility and resilience

   Local models score with low latency and offline capability.

   
   

What You Need Hyperscalers For

1. Analysis of public documents

   Data that's freely accessible doesn't need to be analyzed behind the firewall. Laws? Public tenders? Scientific articles or white papers of any kind? A clear use case for cloud LLMs.

2. Complex, well-defined tasks with large context window

   Large contexts and multimodal applications – that's where cloud IT is at home.

3. Creative tasks

   I know, we're on thin ice here: image generation, graphics for external presentations, or good old web scraping.

   
   

One Catch

There's one thing to keep in mind: hybrid AI is more complex, not simpler, than pure cloud AI. The architecture gets more demanding – there's hardware to manage again (see hybrid cloud above). How do you route prompts to the right AI? Do you explain to employees what to use for which task? That will never work – people take the path of least resistance. So you need automated routing logic.

Which models actually get installed locally, and who takes care of versioning and refresh cycles? (Back to the IT guys in fleece jackets again.) And the eternal topic of governance and auditability: who has access to what, which data is allowed to go where, and how is evidence (logging) generated? A clear task for the Data Security Officer or CIO.

So: local knowledge and local value creation remain in demand.
