Factory CTO says model wars are marketing and the harness matters more
LangChain · x · 2026-07-30
- Factory CTO Eno Reyes argues that much of the so-called model wars are really marketing.
- His core claim: in agentic coding systems, the harness matters more than the model underneath.
- The conversation also covers how Factory builds a 24/7 software factory, why humans in the loop will matter for a long time, and why token routing can materially cut costs.
- Other topics include product management, agent validation, memory, and Factory’s internal lint-checking of its own agents.
