WeChat just dropped WeLM โ their own family of LLMs built for extreme resource efficiency โก
While most labs are racing for larger frontier models, WeLM prioritizes extremely low active parameters (only 3B / 23B) specifically so it can run cost-effectively across 1B+ users inside a closed ecosystem.
The real edge isnโt the parameter count โ itโs the tight integration with Xiaowei + Mini Programs. Thatโs much harder for external models to replicate.
Efficiency + distribution might matter more than pure capability in consumer super-apps. Worth watching.
