Why AI Agents Need the Right Goal, Not an Impossible One
Writer’s Note:
This Article is for those who are building Vertical AI Solutions, for those who believe in science and specially for those who believe LLMs with all these generative powers are still scientific inventions and they fall under rules of mathematics and science
The Illusion of the AI Hype Cycle
Almost every AI startup right now is promising some version of reliable, production-ready agents.
Look at the last few YC batches, close to 90% of the companies are AI-driven, and most of them are vertical AI companies: they don’t build the underlying model, they build a layer on top of one, applying it to a specific industry or workflow.
Marketing budgets are massive, seed rounds are enormous, and the narrative is being scripted largely by frontier LLM providers whose hundred-billion-dollar valuations depend on keeping the hype alive.
I’m a founder building infrastructure in this exact market, and this piece is really about the bet we made, and why we made it instead of chasing the more marketable promise everyone else is selling.
Here’s the question nobody in this market wants to answer directly: has anyone built a core AI primitive that is actually deterministic, the same output for the same input, every time, the way traditional APIs have always worked?
No. And no amount of RAG, added context, or agentic optimization on top of the model changes that.
A History of Patching a Fundamental Flaw
A History of Patching a Fundamental Flaw
When ChatGPT launched, it unleashed incredible generative capabilities.
I will never discredit that — it remains one of the most astonishing technical breakthroughs of our era.
However, as the industry attempted to move from impressive consumer demos to mission-critical enterprise workflows, the core weakness of LLMs became glaringly obvious: their inherent unpredictability.
To solve this, the industry went through rapid layers of band-aids:
Vector Databases: Tools like Pinecone and Chroma brought semantic search into the spotlight.
While useful, vector databases are fundamentally logical evolutions of traditional databases — they simply store mathematical embeddings and allow similarity queries.
Retrieval-Augmented Generation (RAG): RAG was hailed as the ultimate cure for LLM hallucinations and memory limits. The promise was simple: restrict the LLM to your custom data boundaries.
In practice, enterprises quickly learned that RAG merely reduces hallucinations; it does not eliminate them.
Agentic Optimizations: Chaining reasoning steps, adding tool calls, orchestrating multi-agent workflows, these make agents more capable, but every added step is another probabilistic decision, not a step toward predictability.
Observability & Open Knowledge Frameworks: Today, market interest has shifted to observability frameworks, knowledge graphs, and initiatives like Google’s Knowledge Graph solutions.
Every single one of these top-layer solutions attempts the exact same impossible task: forcing a probabilistic system to behave deterministically.
Vertical AI companies are the clearest example of this pattern at scale — they stack RAG, context, and agentic workflows on top of a foundation model, hoping the combination will feel deterministic enough for their customers to trust.
It never quite gets there, because the layer isn’t the problem. The model underneath it is.
[ Traditional Software ] → Input + Deterministic Code → 100% Predictable Output
[ Generative AI Agent ] → Input + Probabilistic LLM → Variable / Evolving Output
Why You Cannot Force Determinism on an LLM
Can a wrapper, an observability tool, or a RAG pipeline fundamentally alter the underlying nature of an LLM? No. The math simply doesn’t allow it.
LLMs are Math, and the Math is Probabilistic At their core, no matter how many hundreds of billions of parameters they have, LLMs perform next-token prediction. They select the statistically most probable answer given a prompt. Probability, by definition, is non-deterministic.
Models Continuously Evolve Frontier models are updated, fine-tuned, and retrained constantly. If a model’s underlying parameters or alignment weights change over time, its outputs will inevitably drift, even when presented with identical inputs. Stack a multi-step agent chain with tool calls and accumulating context on top, and the drift compounds with every added layer instead of canceling out.
If a system relies on probability and undergoes continuous learning, expecting it to produce rigid, 100% deterministic results is a mathematical contradiction.
No stack of tooling on top changes that, it can only ever manage the consequences of it.
The Path Forward: From Determinism to Auditability
Does this mean we should abandon AI agents? Absolutely not.
AI is fundamentally reshaping market dynamics, and its leverage is undeniable.
However, we need to change our approach. Instead of wasting resources attempting to force non-deterministic models into rigid boxes, we must accept their probabilistic nature and focus on Constrained Reliability through Auditability.
You cannot control what you cannot track inside a black box.
If you accept that AI agents will drift, evolve, and occasionally make unexpected decisions, the enterprise requirement shifts from predictability to strict auditability and governance.
And auditability only works as a continuous process, not a one-time fix. A model that drifts today will drift differently tomorrow, after the next fine-tune, after context windows grow, after agent chains get longer.
A one-time audit tells you what happened yesterday. What’s actually needed is a standing process that watches every execution, indefinitely: continuous auditability, paired with human oversight that can intervene before an unexpected decision reaches production, and a feedback loop that keeps improving the system as it evolves.
Run that consistently, and the agent doesn’t become deterministic — it stays sound and reliable anyway, in the way that actually matters to an enterprise: you always know what it did, why it did it, and you catch the moments it goes wrong before they cause damage.
This is the exact realization that shaped what we built.
How ZizkaDB Solves the AI Reliability Problem
This realization is why we built ZizkaDB.
Rather than promising an impossible magic fix that claims to make LLMs 100% deterministic, ZizkaDB is an open-source operational database built specifically for AI agents — providing the continuous state management, behavioral tracing, and auditing infrastructure needed to run autonomous agents safely in production, not as a one-off check but as a standing process.
Here is how ZizkaDB tackles the core enterprise agent problem:
- Causal Lineage & Context Memory (why() and at()) Standard loggers only capture raw input and output, leaving you guessing when an agent makes an erroneous decision. ZizkaDB tracks causal lineage natively (using functions like db.why()).
It allows developers to walk backward through an agent’s execution tree to reveal the exact root cause, parent event, and system state at any point in time.
- Parameter Snapshots & Drift Tracking AI agents change behavior over time as prompt context expands and data accumulates. ZizkaDB records parameter snapshots, context windows, and environmental parameters at execution time.
When an agent’s output drifts, you can isolate and inspect the exact temporal context that caused the deviation.
- Deep Internal Auditing & Human Oversight Instead of treating the agent execution pipeline as a black box, ZizkaDB logs every tool call, context injection, and reasoning step. It integrates seamlessly into production loops with native SDKs for Python, TypeScript, LangChain, CrewAI, and MCP.
This visibility allows teams to trigger real-time human oversight before unintended decisions reach production environments — and to keep refining the system continuously as the underlying model keeps changing.
Conclusion
We do not need more over-hyped promises of 100% autonomous, flawless AI agents.
What we need is pragmatic, robust infrastructure that recognizes AI for what it is: a powerful, probabilistic engine that requires active, continuous governance, not a one-time fix.
You cannot make an AI agent strictly deterministic, no matter how many layers you stack on top of it.
But with ZizkaDB, you can make it auditable, manageable, and trustworthy enough for the enterprise.
