Field Notes

Shorter dispatches from the build — the unglamorous engineering lessons that decide whether AI survives real users.

Webinars

Live sessions and teardowns

We run periodic working sessions where our engineers walk through a real build — the eval harness, the agent architecture, the production hardening — and take questions. Get in touch to be notified of the next one or to request a private session for your team.

Our thinking is grounded in what we ship. Every idea here traces back to a system in production — see the outcomes behind the writing.
