China Telecom AI’s 29-billion-parameter text MoE model for planning, code analysis and sequential engineering problem-solving.

Xing4.0 from China Telecom AI

Xing4.0-29B-A4B is a text MoE model from China Telecom Artificial Intelligence Technology, developed as the next generation of TeleChat. The model has 29 billion parameters, of which approximately 4 billion are active per token. The developer designed it for complex engineering tasks and sequential agentic workflows.

Xing4.0 was trained entirely on Ascend NPU accelerators using MindSpore. Its architecture combines mHC, MLA and MTP; the model contains 40 layers, 64 routed experts, four selected experts per token and one shared expert. These details describe the underlying model’s architecture and research foundation, rather than the hardware processing your request.

Text-based engineering tasks

The developer’s material emphasizes multistep planning, code work and sequential problem-solving. In a text conversation, use these capabilities to prepare a program-change plan, explain dependencies or investigate an error using supplied code. Start with the goal, input data and constraints, then ask for a sequence of actions and the expected outcome of each step.

For a programming task, provide the relevant implementation, data format and an example of expected behavior. A useful result includes an explanation, a localized change and example checks. After running them in your environment, return the observations to the conversation and refine the solution. This keeps the response connected to a specific task without attributing independent project access to the model.

Context and request material

In Ailoot API, Xing4.0 accepts text and returns text. Its context window is 262,144 tokens and its maximum output is 235,929 tokens. Instructions, source material, history and the response share the overall context. You can include several related passages: requirements, documentation, code and verification results. Give them clear names and specify the desired result—a comparison, an algorithm description, revised code or a solution plan.

The developer states that the underlying model’s context can be extended to 512K, but this connection provides 262,144 tokens. Use the latter limit when preparing a large request and leave room for the response.

Connecting to an application

Messages, Responses and Chat Completions are available. These formats help integrate the model into a familiar client and organize several successive messages. This connection returns generated text. Executing proposed code, reading files and working with external tools require the corresponding application logic. The underlying model’s architecture does not itself provide those actions within an ordinary text request.

Questions

How do I choose a model for my task?

First identify the required input and output: text, image, audio or video. Then compare compatible API methods, the exact model ID or current alias target, price and billing unit. GET /v1/models is free and lists models available to your key.

Does each model support every API method and media type?

Use the API methods and input/output types listed on the model card. Support for text, images, audio or video depends on the selected model and method; check their request example before sending your data.

What is the difference between a model ID and an alias?

An exact model ID names a specific model. An alias points to a model and its target can change. Check the current alias target in the catalogue; use the exact ID when your integration needs a specific model.

How do I compare prices before sending a request?

Check the model card for the price and billing unit of the selected API method. Compare the same unit and input/output type; request history shows actual usage and the charged amount.

What does a subscription give me?

A discount on token purchases for regular use. Choose a plan for your request volume; subscription terms and pricing are shown at checkout.

How do I apply a promo code for up to 50% off?

Enter the promo code when buying tokens. The total updates according to the promotion terms; you can see the discount before paying.
