AI Engineering

Quirin Schlegel

I build AI systems that hold up outside the demo.

Retrieval, agents, and the scaffolding around them — embedding pipelines, tool protocols, and the telemetry that tells you when a model has started being confidently wrong.

Answers are generated by an AI model from this site's published notes. How that is handled

  • Retrieval that can cite itself — hybrid vector and keyword search, fused and reranked
  • Agent surfaces with typed tools, scoped tokens, and an audit trail behind every write
  • Tracing across the whole model path, so a quiet regression shows up as a number

How I Work

I care about grounding, latency, and failure modes. AI systems rarely break loudly; they return something plausible and wrong, and keep doing it until somebody checks.

Ground It

Retrieval before generation. An answer that cannot point at its source is a guess with better prose.

Constrain The Surface

Typed tools, explicit schemas, scoped credentials. A model should not be able to reach anything it was never granted.

Instrument Everything

Spans per pipeline stage, token counts, grounding checks. The failures worth fearing are the ones that never throw.

Leave A Handle

Escalation to a human, consent before an agent acts, an audit row after. Autonomy is fine; unaccountable autonomy is not.

What I see

A heads-up display on a pair of smart glasses, wired to this site’s own knowledge base. The panel below is not a screenshot — it is the same 576×288 frame the glasses draw, at the five brightness steps that display actually has, filled from the same endpoint they fetch. Drive it.

On the glasses these are two temple gestures: tap changes channel, scroll changes card. Same frame, same five brightness steps, same data.
