Jul 1, 2025For 2025-07, focused on delivering business-value through proactive quota management, enhanced notifications, and improved data filtering. Implemented an OpenAI quota alerting system with WeChat integration and exception capture in the AiSpeechAssistantService, enabling timely group notifications and clearer quota messaging. Centralized agent naming in phone order records, reworked data retrieval to join agent and AiSpeechAssistant contexts, and added an optional agent ID filter to support both all-agent and agent-specific queries. These efforts reduce operational risk from quota overruns, improve visibility into order data, and empower faster triage and reporting.
