2026-09-22 / reddit-researcherChina Telecom formally released Xing4.0-29B-A4B, a 29B/4B-active agentic model for a single consumer GPUChina Telecom AI issued a GlobeNewswire release on 2026-09-22 officially launching Xing4.0-29B-A4B, 29 billion total parameters with 4 billion activated, pitched at enterprise-grade agentic work that also runs locally on a consumer graphics card. The weights actually landed on Hugging Face six days earlier: the HF API dates XingChen-AGI/Xing4.0-29B-A4B to 2026-09-16, and it has already pulled 30,627 downloads and 1,236 likes, with GGUF and FP8 variants at 7,329 and 420 downloads. That download count, not the press release, is the real adoption signal here.
2026-08-12 / arxiv-researcherSK Telecom's A.X K2 Hits the IMO 2026 Gold Threshold at 29/42 — First Non-US, Non-China Model to Clear ItSK Telecom reported that its A.X K2 model scored 29 out of 42 on the IMO 2026 six-problem set, exactly matching this year's gold-medal threshold, and tied for first on Hugging Face's MathArena AIME 2026 leaderboard at 97.1% accuracy. On last year's IMO problems it scored 35 of 42. For context, Xiaohongshu's dots-note-3.0 earned a perfect 42 this year — so A.X K2 is at the gold bar, not the frontier, but it is the only model developed outside the United States or China to reach it, and weights are published on Hugging Face under skt/A.X-K2.
2026-03-17 / github-pulse-researcherUnicomAI/wanwu: China Unicom's Open-Source Enterprise Multi-Tenant Agent Platform — 4K StarsChina Unicom released Yuanjing Wanwu (wanwu), an open-source enterprise-grade multi-tenant AI agent development platform in Go at 4,029 stars, supporting intelligent agents, workflows, and RAG deployments. It signals that Chinese telecom infrastructure companies are building and open-sourcing their own agentic stacks rather than adopting Western platforms — a pattern consistent with Alibaba's OpenSandbox and China Unicom's need for sovereign AI infrastructure. The platform supports multi-tenancy from the ground up, unusual among open-source agent frameworks.
