Poolside’s Laguna S launch spotlights 118B open-weight model economics
Madison Kanna’s interview frames Poolside’s Laguna S launch as a bigger argument about American open-source AI. The conversation covers:
- Laguna S specs: 118B parameters with 8B active parameters, built in 8 weeks.
- Architecture choices: sliding-window attention and a claimed 1M context window.
- Strategy: why Poolside decided to open its models and what “the oligopoly on intelligence” means.
- Industry angle: the economics of open weights and who gets to build intelligence over the next 12–18 months.
The post positions the launch as both a model release and a debate about the future of software engineering, where “behaviors over IQ” may matter more than raw benchmark chasing.
