- Full-chain Monitoring and Operations - Offers real-time invocation logs, token consumption analysis, conversation funnel statistics, and effect dashboards, with support for alert settings and canary releases to ensure stable online operation of applications.
- Ecosystem Plugins and Tool Integration - Includes official plugins such as search, calculator, image generation, and code interpreter, and supports custom API plugin integration, enabling agents to invoke external systems.
- Register and Log In - Log in to the Bailian console (bailian.console.aliyun.com) using an Alibaba Cloud account. New users can claim free quota. If you don't have an account, you must first complete Alibaba Cloud real-name verification.
- Select a Model and Create an Application - Navigate to the model marketplace, choose a suitable model (e.g., qwen-plus), and enable the service. Then create an agent application in the "Application Plaza" and use templates (such as customer service bot or knowledge Q&A) for a quick start.
- Configure and Test - In the application editor, write the system prompt, add knowledge bases or plugins, and conduct dialogue tests via the right-side chat panel. Adjust parameters such as temperature and max_tokens.
- Publish and Integrate - After testing is complete, publish the application, obtain the API key and invocation address. It can be integrated into channels such as WeChat, DingTalk, Web, or mini-programs, or directly invoked via SDK for code integration.
Example 1: Enterprise Intelligent Customer Service - Prompt: "You are the after-sales customer service for an e-commerce platform and need to answer questions about the return process. Please respond in a friendly and professional manner based on the following knowledge base content: \"Returns must be initiated within 7 days of receipt, and the product must be in good condition and not affect secondary sales.\"" Expected output: The system automatically retrieves the knowledge base and generates a reply like "Hello, according to our after-sales policy, you can apply for a return within 7 days of receipt. Please ensure the product is in good condition, and we will process your return request."
Example 2: Content Creation Assistance - Prompt: "Please write a WeChat public account article about 'green urban transportation,' about 800 words, including 3 core suggestions and vivid examples." Expected output: The platform generates a well-structured and naturally styled article, including suggestions on shared bikes, public transportation optimization, and electric mobility, with an engaging introduction and a concluding call to action.
Example 3: Data Analysis Script Generation - Prompt: "Use Python to generate a code snippet that reads sales data from a CSV file, calculates the quarterly sales growth rate, and plots a bar chart using matplotlib." Expected output: The platform directly outputs runnable Python code with necessary comments and an explanation of the generated chart.
- Alibaba Cloud Ecosystem Integration - Seamless integration with Alibaba Cloud's big data, database, Function Compute, and other products allows for rapid cloud deployment and access to enterprise-grade security and compliance certifications (e.g., MLPS, ISO).
- Balanced Model Performance and Cost - The Tongyi Qianwen series excels in Chinese-language tasks while offering multiple tiers (turbo/plus/max) to match business precision requirements, with pricing significantly lower than some international large models.
- Visualization and Low Barrier - Non-technical personnel can build agents through drag-and-drop, greatly lowering the threshold for AI application development and shortening the cycle from idea to launch.
- Flexible Private Deployment - Supports deployment in Alibaba Cloud's proprietary cloud or hybrid cloud environments, meeting strict data sovereignty requirements of industries such as finance and government.
- Continuously Updated Toolchain - The Bailian platform updates features monthly, including new plugins, evaluation tools, and model versions, keeping the platform at the forefront.
Baidu Qianfan - Also a leading domestic platform, Baidu's ERNIE model is competitive in Chinese comprehension, but Bailian offers more flexibility in model selection (multi-model mixed invocation) and Alibaba Cloud's enterprise-grade services.
- ByteDance Coze - Coze focuses more on C-end users and creative agent building, while Bailian emphasizes large-scale enterprise applications, high concurrency, and stability assurance.
- Dify/Open-source Frameworks - Open-source solutions can be self-hosted, but Bailian provides more comprehensive managed operations, multi-tenant isolation, and Alibaba Cloud technical support, making it suitable for teams that do not want to build their own infrastructure.
