Evaluation harnesses, tracing, observability, guardrails and prompt management.
Hybrid code review that puts deterministic rules first and the LLM second — the only ordering that survives an enterprise security review.
Validates model output against a schema instead of hoping — and re-asks when validation fails.
LLM traces as standard OpenTelemetry spans — so they land in the observability stack you already pay for.
Self-hostable tracing, evals and prompt management — the observability layer most teams forget to build.
Metric suite for RAG: faithfulness, context precision, recall — the numbers you need before a go-live review.
Notebook-first observability with clustering that surfaces failure modes you did not think to test.
Drop-in proxy that logs every request and shows cost per user, per feature, per day.
Self-hosting beats the API on cost per token only above a utilisation threshold almost nobody reaches. Below it you are paying for idle silicon and engineer attention — and only o…
Teams that measure tend to measure the easy cases, because those are the ones where someone already knows the answer. The questions that will cost you money are the ones nobody th…
Routing is the highest-leverage cost control in an LLM system, and it is almost always implemented last, after eighteen months of paying premium prices for questions a smaller mod…
Every team that runs an agent in production eventually builds the same thing: a suite of scenarios that must not regress. The only question is whether you build it before or after…
