Poolside: Laguna M.1 (free)

Poolside Laguna M.1 (free) is a text-in, text-out model with a 262,144-token context window and a 32,768-token output ceiling. It supports tool use and reasoning, which makes it applicable to agentic workflows and multi-step problem solving. Structured output support is unconfirmed, so developers who depend on guaranteed JSON schemas should verify that before building around it. The model costs nothing, which makes it a low-friction option for experimentation, prototyping, or cost-sensitive projects. The practical tradeoff is that it carries no independent benchmark coverage at this time, so there is no external data to calibrate its quality against paid alternatives. Teams comfortable evaluating a model through their own task-specific testing will find the price point easy to justify; teams that need documented performance evidence before committing should treat it as unproven for now.
