China Telecom AI Releases Lightweight Agentic Model Xing4.0-29B-A4B

BEIJING, Sept. 22, 2026 /CourierPR/ -- China Telecom AI has recently officially released Xing4.0-29B-A4B, its next-generation lightweight agentic large model. With 29 billion total parameters and 4 billion activated parameters, the model provides enterprise-grade agentic capabilities at an extremely low compute threshold. It can be deployed in large-scale enterprise production environments or run locally on a personal consumer-grade graphics card, offering developers and enterprises a highly cost-effective AI agent solution.

Built on a next-generation Mixture-of-Experts (MoE) architecture, Xing4.0-29B-A4B is purpose-built for the agentic era. Unlike conventional interactive models that focus on question-and-answer exchanges, this model places greater emphasis on execution. It can independently plan multi-step task paths, call external tools, process long-context inputs, and deliver completed results. With an ultra-long 256K-token context window, the model is well equipped for complex engineering tasks that require sustained reasoning across a large number of documents.

Speed Meets Efficiency Xing4.0-29B-A4B strikes an optimal balance between inference speed and task complexity. By activating only 4 billion of its 29 billion parameters per token, the model delivers near-instantaneous responses to simple queries while still being able to draw on its full capacity for highly demanding multi-step tasks. This combination of deep reasoning power and responsiveness makes it a valuable tool for developers and enterprises.

Single-GPU Deployment: From Data Center to Desktop Using low-bit quantization and memory optimization techniques, Xing4.0-29B-A4B requires only 15 GB of GPU memory, which means it can run locally on a single consumer-grade graphics card. This dramatically lowers the infrastructure barrier for developers and enterprises building AI agent applications, eliminating the need to invest in expensive multi-GPU server clusters. For individual developers and technology enthusiasts, Xing4.0-29B-A4B delivers a fully local AI agent experience with complete privacy control. Users can run sophisticated agent workflows, including code development, data analysis, and document processing, entirely on their personal devices, with no data leaving their device.

Compact Size, Complete Capabilities Despite its small size, Xing4.0-29B-A4B offers complete agentic capabilities. The model performs strongly across a range of core benchmarks, covering multi-step agent task completion, function-calling accuracy, long-context retrieval, JSON format compliance, and code generation. On the SWE-bench Verified benchmark, Xing4.0-29B-A4B scored 75.0 out of 100, ranking among the top models in its parameter class.

Proven in Production Xing4.0-29B-A4B has been deployed and validated in real-world enterprise environments. China Telecom has integrated the model into its group-level customer service platform, where it handles complex customer inquiries through multi-step reasoning and tool-calling workflows, significantly improving first-contact resolution rates and average handling efficiency. The model is also deployed in "mid-screen" interactive service scenarios, providing real-time, context-aware intelligent assistant services to customers in home service environments.

These production deployments demonstrate that Xing4.0-29B-A4B is not only a research benchmark but also a battle-tested, production-ready model that delivers measurable business value for customers.

Open Ecosystem Following its open-ecosystem strategy, China Telecom AI has released Xing4.0-29B-A4B on major open-source communities such as GitHub and Hugging Face. The model is compatible with mainstream open-source training, inference, and agent development frameworks and has been validated across a range of domestic and mainstream AI chip platforms.

The Xing4.0 model series is currently powering over 500 enterprise workflows across more than 20 industries worldwide. Through continuous innovation, China Telecom AI is committed to driving digital transformation and establishing AI as a primary engine for modern productivity.
