An eval harness you trust
How to build offline and online evals that actually catch regressions — golden sets, LLM-as-judge done carefully, and the metrics that correlate with real user pain.

Free live webinar · Thursday, September 24, 2026 · 11:00 AM PT · Online
A free 90-minute live session for engineers shipping AI agents past the demo stage. We go deep on the three things that decide whether an agent survives real traffic: evaluation you can trust, guardrails that hold, and cost that stays under control. Live demo, live Q&A, recording sent to everyone who registers.
What you'll take away
No slideware theater. Every segment maps to a decision you have to make when an agent leaves the demo and starts handling real users.
How to build offline and online evals that actually catch regressions — golden sets, LLM-as-judge done carefully, and the metrics that correlate with real user pain.
Input and output validation, tool sandboxing, and permission layers that stop an agent from doing damage — shown live on a working agent, not on slides.
Model routing, prompt caching, and per-request budgets that cut spend 40-70% without gutting quality. Real numbers from real production traffic.
The five ways agents break in production — runaway loops, silent tool errors, context bloat, eval drift, and cost blowups — and how each team we work with fixes them.
Everyone who registers gets the full recording, the slide deck, and a starter repo with the eval and guardrail patterns from the demo — sent within 24 hours.
A real Q&A block where the presenters take your hardest production questions on camera. Bring the problem you're stuck on right now.
Agenda
All times Pacific. We start on the hour, keep the talks tight, and leave a real block for your questions. The whole thing wraps in 90 minutes.

Your presenters
Three engineers who ship agents to production every week — not analysts talking about it from the sidelines.

Host · Co-founder, Runtime
Has shipped LLM products since the GPT-3 beta and now leads applied AI at Runtime. Your host for the session — keeping the pace tight and the demos honest.

Presenter · Staff AI Engineer
Builds the evaluation and cost-control tooling behind agents serving millions of requests a day. She will walk through the eval harness and the routing tricks that keep bills sane.

Presenter · Principal Engineer, Platform
Runs the sandboxing and guardrail layer that lets agents call real tools without breaking things. He drives the live demo, wiring guardrails into a working agent on screen.
The essentials
It's online, it's free, and the replay is yours whether or not you can make the live time.
Thursday, September 24, 2026, 11:00 AM Pacific (2:00 PM Eastern / 6:00 PM UTC). Runs 90 minutes, including live Q&A. Can't make it? Register anyway and we'll send the recording.
Online, live on Zoom. There's nothing to travel to — your private join link and a calendar invite are emailed the moment you register, with a reminder an hour before we go live.
Engineers, ML/AI leads, and technical founders who already have an agent or LLM feature running — or about to ship one — and want it to hold up under real traffic. Free to attend.
Register once and you're set: private join link, calendar invite, and the recording afterward, even if you can only catch the replay.
