Everyone is talking about better prompts, better models, and better agents.
But production AI systems are not failing only because the model is we...

This:
"Build a control plane for AI actions"
That's my 7-word takeaway ...
That’s honestly one of the most accurate summaries I’ve seen.
What surprised me while working on real systems is that teams invest heavily in the model layer, but almost nothing in the decision layer that governs how outputs turn into actions. That gap is exactly where things start breaking in production.
A proper control plane is not just validation, it includes:
policy enforcement (what the model is allowed to do)
confidence-aware decision routing
guardrails for irreversible actions
observability on decisions, not just predictions
Without that, we are basically letting probabilistic systems operate like deterministic ones, which is risky at scale.
Your 7 words capture the core problem better than most long write-ups.
Thanks! But the rest of your article provides the detailed context, without which the 7 words would be pretty meaningless :-)
Totally fair point 🙂
The 7 words are just the hook, but you're right, the real value is in unpacking what sits behind them. Without the context of how decisions are actually made, routed, and constrained, that statement doesn’t carry much weight.
That gap between "prediction" and "action" is where most production failures quietly originate, and that’s what I wanted to make visible.
Your approach seems sensible - hopefully companies will have enough common sense to adopt such an approach/strategy!
Appreciate that!
I think most teams actually agree with this in principle, but where it breaks down is in execution. Building a proper decision layer isn’t just a mindset shift, it needs ownership, tooling, and iteration loops, which many orgs don’t plan for upfront.
In a lot of cases, people only realize its importance after something goes wrong in production 🙂
Hopefully we’ll start seeing it treated as a first-class part of AI systems, not an afterthought.
Did you had any issues to build a control plane for AI actions?
Yes, quite a few, and most of them were not obvious at the start.
The biggest challenges I ran into:
Defining decision boundaries
Models don’t give clean “yes/no” outputs. Translating probabilities into actionable thresholds without breaking user experience is tricky.
Handling uncertainty properly
Confidence scores are often poorly calibrated. Without calibration, the control plane either becomes too strict or too permissive.
Policy vs flexibility tradeoff
Hard rules improve safety but reduce system usefulness. Finding the right balance required multiple iterations and real-world feedback loops.
Latency overhead
Adding a decision layer (validation, routing, checks) introduces latency. Optimizing this without removing safeguards was challenging.
Observability gap
Traditional monitoring focuses on system metrics, not decision quality. Building visibility into why a decision was taken was critical and non-trivial.
Edge cases in production
The model behaves differently under real traffic compared to offline evaluation. The control plane has to handle those long-tail cases.
Overall, building the control plane ended up being more complex than the model itself, but also far more important for production reliability.
ok! I see and interesing
Yeah, quite a few and most of them only became obvious after seeing failures in production.
What stood out the most was that the hard problems aren’t in modeling, they’re in translating model outputs into reliable decisions.
Things like:
A lot of systems look fine offline, but break under real-world edge cases and traffic patterns. That’s where the control plane really proves its value.
oh wow!
I really appreciate your emphasis on the "decision layer." Once during a e-commerce project, I discovered that a model that’s picking up on a fake listing is only half the battle. Ultimately, though, the trick is deciding whether to flag or delete it automatically. And if that logic is buried in a prompt, it’s a nightmare to debug. I agree that it is best to keep rules in the code so you can retain control. Do you think rigid policies might limit flexibility?
