Poolside: Laguna XS 2.1 (free)

Laguna XS 2.1 sits in Poolside's Laguna family of coding-focused agent models and is positioned as a step forward from the earlier Laguna XS.2 released in April 2026. It is described as the latest coding agent model in the 33B-A3B category, blending reasoning and tool calling in a compact footprint, and is quantized to FP8 so it can serve fast, cost-efficient agentic coding workloads. The 256K context window and 32K output ceiling are sized for the kind of long, multi-file programming sessions that agent harnesses tend to produce.

Because the model is offered on a free tier through the Kilo Gateway, its strongest use case is exploratory or high-volume agentic coding where iterative tool use and structured reasoning matter more than raw frontier accuracy. The compact FP8 design makes it well suited to code generation, refactoring, and tool-driven development flows inside Kilo's open-source IDE, CLI, and cloud agents. Teams that need a no-marks-up coding model for routine software engineering tasks will find the most natural fit, while paying customers comparing it to larger models should weigh the smaller parameter count against the savings.

Coverage

The Enterprise DNA (EDNA) Models directory entry for "Laguna XS 2.1 (free) by Poolside" (added July 10, 2026) is a derivative listing that mirrors the OpenRouter catalogue for the same subject model. It reaffirms that Laguna XS 2.1 is Poolside's latest coding agent model in the 33B-A3B category and that it succeeds the Because EDNA is a third-party directory rather than an official Poolside or Kilo source, the page provides no independent benchmark numbers, no licensing terms (OpenMDW-1.1), and no novel technical claims beyond restating the OpenRouter description. Its value is limited to confirming broad catalogue availability of the
