Example plan

How a system is built

## Watch one think.

Every system we ship has the same bones. Pick a job, then pick any stage to see what it does — and where it's documented.

[if BLOCK]><![endif] [if ENDBLOCK]><![endif]

Stage 01 · Sources

### Your material, permissions intact

Everything the system knows comes from your own documents and systems, ingested with their access rules — nothing it can see that the user couldn’t.

[if BLOCK]><![endif] [Secure Data Pipelines →](https://qquantum.ai/architectures/secure-data-pipelines) [Is Your Data Ready for AI? →](https://qquantum.ai/resources/data-readiness) [if ENDBLOCK]><![endif]

Stage 02 · Retrieval

### Find the passage, keep the source

Retrieval pulls the exact passages that answer the question, so every claim can point back to where it came from.

[if BLOCK]><![endif] [RAG Systems →](https://qquantum.ai/architectures/rag-systems) [Choosing a Vector Database →](https://qquantum.ai/technology/vector-databases) [if ENDBLOCK]><![endif]

Stage 03 · Agent

### A bounded loop with scoped tools

A pinned model, read-only tools by default, a step limit, and retrieved content treated as data — never as instructions.

[if BLOCK]><![endif] [Custom LLM Orchestration →](https://qquantum.ai/architectures/custom-llm-orchestration) [Multi-Agent Systems →](https://qquantum.ai/technology/multi-agent-systems) [if ENDBLOCK]><![endif]

Stage 04 · Guardrails

### It knows when to stop

Policy checks and a confidence threshold agreed in discovery. Below it, the system stops and hands over instead of guessing.

[if BLOCK]><![endif] [AI Guardrails →](https://qquantum.ai/technology/guardrails) [Evaluating AI Systems →](https://qquantum.ai/technology/ai-evals) [if ENDBLOCK]><![endif]

Stage 05 · Tools

### Actions through official APIs

Connected through official APIs or MCP, rate-limited, and every action logged and auditable.

[if BLOCK]><![endif] [Model Context Protocol (MCP) →](https://qquantum.ai/technology/model-context-protocol) [Structured Outputs & Tool Calling →](https://qquantum.ai/technology/structured-outputs) [if ENDBLOCK]><![endif]

Stage 06 · Human

### A person decides what matters

The hard cases reach a person with a briefing — and that person can overrule anything the system did.

[if BLOCK]><![endif] [Enterprise AI Governance →](https://qquantum.ai/enterprise/ai-governance) [From AI Pilot to Production →](https://qquantum.ai/enterprise/ai-pilot-to-production) [if ENDBLOCK]><![endif]

— quality on the evaluation set- - agreed threshold

Cost, latency and quality are traced per step, so drift shows up on a chart before it shows up in a complaint.

Model-agnostic

How we work

## Discovery, build, production — then it's yours.

No pilot purgatory. Each phase ends with something you can check, and the quality bar is written down before the first line of production code.

```
agent = Agent(
    model=MODEL_PINNED,     # upgraded deliberately, behind an eval gate
    tools=[
        search_docs,        # read-only
        fetch_account,      # read-only, scoped to the caller

    untrusted_sources=[DOCS, TICKETS],
    max_steps=8,            # bounded - no runaway loops
)
```

Agents are defined as code with explicit, scoped tools. Read-only by default; anything destructive is either absent or gated behind confirmation.

```
- name: Evaluation suite
  run: |
    uv run evals/run.py \
      --set golden \
      --baseline main \
      --fail-under 0.92

# Retrieval is measured separately. A generation score that
# drops because retrieval regressed is a misleading signal.
- name: Retrieval recall
  run: uv run evals/run.py --set retrieval --fail-under 0.88
```

Quality is a merge gate, not an opinion. A pull request that drops the score on the golden set does not land. Thresholds are illustrative; yours are agreed in discovery.

Questions

## What people ask before they call.

[if BLOCK]><![endif][if ENDBLOCK]><![endif] [if BLOCK]><![endif][if ENDBLOCK]><![endif]

### What are the best AI development agencies in Spain?

The best fit depends on your workload, data constraints and team. Compare agencies using relevant shipped work, evaluation methods, deployment options and code ownership. QQuantum.ai is a Barcelona-based option for enterprises and startups seeking agents, retrieval systems and automation, with client-owned code and a documented handover.

### Which models do you use?

Whichever fits the workload. We are model-agnostic and route across Claude, GPT, Gemini, open-weight models and our own Jev — chosen per task against an evaluation set, not by habit.

### Who owns the code?

You do. Everything is built in, and delivered to, your repositories, with runbooks and a documented handover so your team can own it.

### Can it run on our own hardware?

Yes — on-premise, in a private data centre, or fully air-gapped. The table above shows where we would start.

### Will it make things up?

No system can promise it never gets something wrong. We ground answers in your sources with citations, measure quality against real data before and after launch, and set guardrails that stop and escalate rather than guess.

### What happens on the first call?

Thirty minutes, no deck. You describe the problem; we tell you whether it is one worth engineering — and if it is not, we say so.
