Direct LLM
integration guide.
A 15-page engineering guide to integrating directly with the LLM API the way you integrate with Postgres. No agent frameworks. No orchestration vendors. Code samples and runbook templates included.
WHAT'S INSIDE · 05 CHAPTERS
Five chapters. For engineers.
01
Auth, retries, and the basics nobody documents
Idempotency keys, exponential backoff, request hashing for replay debugging.
02
Structured output without a framework
JSON-schema, function-calling, and the four failure modes you need to handle.
03
Embeddings and retrieval, from scratch
pgvector, hybrid search, why your “cosine similarity is bad” problem is actually a chunking problem.
04
Eval suites your team will actually maintain
How to write 50 examples that beat 5,000, plus the CI integration that keeps them honest.
05
Observability for LLM systems
Latency, cost, quality, and prompt-injection telemetry in one dashboard. Tooling we use, in order.
