Independent use will determine whether Poolside's updated Laguna S 2.1 FP8/NVFP4 weights fix prior looping failures while reliably supporting the new million-token context.

What is this?

Poolside released Laguna S 2.1, an open-weight agentic coding model with a 118B-parameter mixture-of-experts architecture and 8B parameters active per token, designed for local deployment and long-running coding agents. Poolside claims native support for context windows up to one million tokens, although its NVFP4 checkpoint is configured and recommended at 262,144 tokens for best quality, while one independent forum benchmark tested only 131,072 tokens. Updated FP8 and NVFP4 weights are reported as targeting prior looping failures, but the supplied snippets do not establish that those failures are fixed or independently validate reliable operation at one million tokens.

Why it matters to Scott

No intersection found in Scott’s wikis, and no radar pages show that this development or its actors are already tracked. The supplied material therefore cannot establish that the weight updates or million-token-context claims bear on a position or project Scott holds.
