What Poolside AI does
Poolside builds open-weight foundation models for agentic coding, along with the systems used to refine and improve them. It is aimed at developers building with coding agents, as well as government teams and researchers. Its Laguna models include Laguna s 2.1, with 118B parameters, 8B active and 1M context, positioned as frontier-class reasoning at mid-size cost, and Laguna xs 2.1, with 33B parameters, 3B active and 256K context, small enough to run on-device. The pool terminal interface offers slash commands, mode cycling, model selection, tool grouping and connection to an agent server. The models are also reachable through OpenRouter and Vercel AI Gateway. No pricing appears on the site.
