AI:AM LIVE — July 8, 2026 — LTX's Zeev Farbman on Open World Models, GPT-5.6 Cleared for Launch, and Hosts vs. the AI Superforecasters

A three-act Wednesday show. Nathan and Prakash opened with the machinery around the models: all three GPT-5.6 models (Sol, Terra, Luna) were cleared to launch publicly the next day, July 9, after Commerce's CAISI review — making GPT-5.6 the first frontier model to graduate the June EO's pre-release gate rather than be stopped by it (as of air time it remained a ~20-partner API preview, not GA) — the same 48 hours OpenAI's exhibition model beat the human field at the AtCoder World Tour Finals, with AtCoder's own president conceding 'total defeat to AI.' The hosts then took on Anthropic's 'global workspace' paper (Jul 6, 2026) — a privileged, small slice of Claude's activity that supports multi-step reasoning and experiential language, and the consciousness-framing fight it ignited from OpenAI's Boris Power to Neel Nanda and Eleos AI — plus Replit's claim to have 'closed the loop' on a self-improving agent read through Lilian Weng's harness-engineering lens, and a same-week regulatory split-screen: Beijing weighing export curbs on China's top models (open weights included, per Reuters Jul 7) while Illinois signed SB 315, first-in-nation annual safety audits for frontier developers, with Coefficient Giving's reported $160M grant to Geoffrey Irving's Resolution rounding out the block. Then Zeev Farbman — co-founder and CEO of LTX, the Facetune founder who split Lightricks in two on June 1, 2026 to go all-in on open world models — joined for a 48-minute conversation built around the open-weights bet in AI video: why he took ~250 people and the models while Facetune kept the cash cow, the Red Hat-style licensing math of giving away weights free under $10M ARR, LTX-2.3's #1 open-weights ranking on Video Arena (Jun 30, 2026) versus the closed frontier's compute advantage, video models as world models with implicit physics, robotics teams fine-tuning owned weights inside their own environments, and what responsible deployment means for open video. Finally, the longest segment of the day: 'Predictions & FutureSearch,' the hosts-versus-the-AI-superforecasters rematch teased on Monday's Dan Schwarz episode — a 'Guess the Market' round with Nathan and Prakash calibrating against live prediction-market odds on AI questions and comparing their guesses to FutureSearch's AI forecasting agent.
