Madisonkanna · x · 2026-07-22
AI coding company Poolside has launched Laguna S, an open-source model with 118B parameters (8B active), built in just 8 weeks. The model features 1M context and utilizes sliding window attention.
The founder discussed the economics of open weights, breaking the 'oligopoly on intelligence,' and the future of software engineering (emphasizing behaviors over IQ). Positioning Poolside as an American open-source lab, he highlighted that the next 12–18 months are a critical window to decide 'who gets to build intelligence.'
