China Telecom Artificial Intelligence Technology released Xing4.0-29B-A4B, a lightweight agentic model: 29 billion total parameters with only 4 billion activated per token, per the company's announcement. It is a next-generation MoE aimed at agentic execution — multi-step planning, tool calls, long-context work — with a 256K-token context window, designed to run locally on a single consumer GPU or scale to enterprise production.

Corroboration check: single-source company announcement, not independently verified — treated as released on the company's say-so, consistent with the site's convention for Chinese-lab company announcements.
