Nathan Lambert: Jensen Huang's exit is a decapitation for Nvidia's open-model bet

Nathan Lambert argues Nvidia CEO Jensen Huang's resignation is a major setback for the US open model ecosystem.

Jensen's operating role was central to Nvidia; further departures (chip-smuggling probes, poached talent) are plausible, and the top priority is stabilizing the ship and delivering over the next 24 months.
Open models were one of Jensen's founder-style bets, funded aggressively — that support will likely dry up.
Nvidia still has business reasons to back open models (avoiding customer concentration and custom-chip defection), but sustaining the ecosystem is a business puzzle, not an engineering grind.
These nascent years are crucial for establishing use cases and revenue; the open ecosystem's edge is "ownership of intelligence" and enterprise post-training.
