Poolside Releases Laguna S 2.1 Open-Weights Coding Model

Episode 1 · Poolside Releases 118B Open-Weight Coding Model Laguna S 2.1 (2026-07-22, 27 posts)

Poolside has launched Laguna S 2.1, its latest open-weight coding model, focusing on agentic coding and long-horizon tasks. The model supports a context length of up to 1 million tokens. The company emphasizes its stable performance in long-chain tasks, noting that its agentic coding capabilities surpass some larger models.

Key Details

Laguna S 2.1 utilizes a MoE (Mixture of Experts) architecture with a total of 118B parameters, activating 8B parameters per token. Released under the OpenMDW license, its open weights are well-suited for extended autonomous operations by local coding agents. In terms of performance, official benchmarks reveal leading scores on tests like Terminal-Bench 2.1. Additionally, NVIDIA shared and endorsed the model, acknowledging its ability to pack strong capabilities into a compact size.
