Poolside releases Laguna XS.2, M.1

This is more than a model drop: Poolside is shipping a full coding stack, with models, an agent runtime, and product surfaces for both terminal and cloud workflows.

• –XS.2 being open-weight under Apache 2.0 makes it the developer-friendly headline; it lowers friction for local runs, fine-tuning, and self-hosted experimentation
• –M.1 is the scale play: 225B total parameters with 23B active positions Poolside as aiming above the “small open model” tier and into serious frontier-coding territory
• –The benchmark claims are strong enough to matter, especially on SWE-bench Pro and Terminal-Bench 2.0, but they’re still company-published numbers and should be read as directional
• –Releasing `pool` and `Shimmer` alongside the models suggests Poolside wants to own the agent workflow, not just sell raw weights
• –The limited-time free access is a smart distribution move: it seeds adoption quickly before the models become another paid API in the crowd
