Laguna S 2.1 Released: Cheaper than Deepseek v4 Flash, Better than V4 Pro

Explain Like I'm Normal

Laguna S 2.1 is a new locally-runnable model that claims to outperform DeepSeek v4 Pro across major coding and reasoning benchmarks. Using an 118B MoE architecture with only 8B active parameters, it targets high-end consumer hardware like Mac Studios and multi-GPU setups. This release further accelerates the trend of open-weight models matching or beating frontier-level proprietary APIs in specialized coding tasks.
