Agentic AI at Two Different Scales: Nanbeige4.2-3B and Laguna S2.1
It is intended to make capable agentic behavior practical on consumer and workstation hardware.Laguna S 2.1 is a 118-billion-parameter Mixture-of-Experts (MoE) model. It activates approximately 8 billion parameters for each token.The two models represent different approaches to agentic AI. The same weights are reused during the second pass, giving the model the computational depth of approximately 44 layer executions without storing 44 independent layers.This design reduces weight memory, but it does not reduce inference computation to that of a normal 22-layer model.

Agentic AI at Two Different Scales: Nanbeige4.2-3B and Laguna S2.1 The Weekly Kaitchup #152Benjamin MarieJul 25, 202692ShareHi everyone,In this edition of The Weekly Kaitchup, I’m looking at two of the week’s most interesting releases for agentic workloads: Nanbeige4.2-3B and Laguna S 2.1.The Kaitchup – AI on a Budget is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber.SubscribeAgentic workloads include multi-step reasoning, tool use, interaction with external environments, and tasks that may require many actions before completion.Nanbeige/Nanbeige4.2-3Bpoolside/Laguna-S-2.1Despite this shared focus, they operate at very different scales.Nanbeige4.2-3B is a compact dense model with approximately 4 billion total…
