Summary
This workshop centers on Will Brown's Prime Intellect work on open post-training infrastructure: the verifiers and prime-rl libraries, plus the Prime Intellect Lab platform for self-serve training and inference. The connected supporting video and extracted slides, "Training Agentic Reasoners," frame the topic around building and training agentic reasoning systems rather than treating reasoning as only a prompt-engineering problem. Read the linked YouTube material as adjacent context from the same speaker and organization, not as a confirmed recording of this exact World's Fair workshop.

Hey guys, how's it going? Thanks for showing up. This was a little bit of a last-minute assembly. I know a few days ago I was like talking to Swix.

Evidence Boundary
This synthesis uses the official schedule plus cached video transcripts. Official AI Engineer World's Fair San Francisco 2026 livestreams and cut videos are primary event video sources for transcript/slide evidence; external, historical, or speaker-matched videos remain supporting context unless manually verified as exact official event recordings.
Official YouTube Recording
- youtube V EDrhIhHzQ — official AI Engineer YouTube channel recording published 2026-07-13.
- Evidence status: youtube V EDrhIhHzQ transcript; youtube V EDrhIhHzQ slides.
- Boundary: use this recording as media evidence; keep date/time/room facts tied to the official schedule.
