LangChain webinar: fast, cheap Jev models make real-time filtering and guardrails viable
LangChain · x · 2026-09-25
LangChain released the recording of its "Building a Harness with Jev" webinar with TypeSafe (48 min). The takeaway from Sydney Runkle: because Jev models are fast and cheap, they enable genuinely real-time inference —
- real-time content filtering on streams
- guardrails with no real UX cost
- monitoring and steering agent trajectories without prohibitive expense
The session also covers the LangSmith agent development lifecycle (build-test-deploy-monitor), model routing, confidence thresholds, and agent safety controls.
