Poolside AI's Eiso Kant on building a model factory and training Laguna S, a 118B MoE model

Latent Space interviews Poolside AI co-CEO Eiso Kant about how a small research team built a model factory capable of training Laguna S, a 118B mixture-of-experts model that reportedly outperforms Thinky's approximately 1T open-weights model. The conversation covers the organizational and technical approach behind Poolside's training infrastructure and research process. Poolside is a code-focused AI lab, and this signals meaningful progress in efficient large-scale MoE training by a smaller team.
