WeChat Pay releases AI Toolbox 2.0, converting all charts to Mermaid and halving the token consumption for AI.

According to Bijie.com, WeChat Pay today released AI Access Toolkit 2.0, a comprehensive upgrade to its knowledge base and development tools for large-scale model integration. The toolkit converts all sequence diagrams and state diagrams in the documentation to Mermaid format, making it directly readable for models without multimodal capabilities. Overall token consumption is reduced by 50% compared to the original HTML. To eliminate machine translation bias, the toolkit supports nine languages, including Chinese, Japanese, and Korean, and provides translation and adaptation for native concepts such as "WeChat Pay Cashier." The knowledge base content has expanded from payment and coupons in version 1.0 to cover all WeChat Pay products. It also provides two AI expert capabilities: technical experts and financial-grade R&D experts, supporting troubleshooting Q&A and code quality review. In terms of development experience, the newly added CLI dynamic troubleshooting function allows developers to directly query payment and refund status using natural language on the terminal, avoiding interruptions to coding flow when logging into the merchant backend. Skill also automatically compares the official website and local knowledge base versions upon startup, achieving automatic synchronization and updates.
