Value Shifts to AI Harnesses: DeepSeek Gives It Away, SpaceX Pays $60B
julsimon · x · 2026-08-21
Julien Simon argues that AI value has shifted from models to the "harness" layer.
- DeepSeek Harness: Open-sourced an MIT-licensed agent framework, gaining 160k stars in 6 days. Price: $0.
- SpaceX Acquisition: Paid $60B for Anysphere (maker of Cursor), buying a harness business.
- OpenAI Costs: Revealed that supervising its own models consumes 20% of monitored compute, pausing a major RL run for safety reasons.
All three events signal that the scaffolding layer is no longer just plumbing, but the contested asset of the AI stack.
