A Dream of Spring for Open-Weight LLMs: 10 Architectures from Jan-Feb 2026

A comprehensive architectural survey of 10 open-weight LLM releases from Jan-Feb 2026, covering models from Arcee AI, Moonshot AI, Alibaba's Qwen team, Cohere, and others. The piece focuses on architectural similarities and differences — MoE configurations, active parameter counts, and design choices — across models ranging from 3B to 1T parameters. A useful reference for engineers tracking the open-weight landscape and evaluating models for local/production deployment.
