From 1f2eaf69743331a85aa42ba29babb889b8a57c25 Mon Sep 17 00:00:00 2001 From: Max Date: Sun, 27 Jul 2025 15:35:55 +0800 Subject: [PATCH] Refactor Agent API to Chat API for AI interactions - Replaced the Agent API with the Chat API, focusing on AI chat completions with full OpenAI client compatibility and real-time streaming capabilities. - Updated routing to attach chat handlers instead of agent handlers, ensuring OAuth protection for all endpoints. - Revised README documentation to reflect the new Chat API structure, including detailed descriptions of endpoints, features, and usage examples. - Removed the deprecated agent files and their associated documentation to streamline the codebase. --- openapi/README.md | 99 ++-- openapi/agent/README.md | 337 -------------- openapi/chat/README.md | 553 +++++++++++++++++++++++ openapi/{agent/agent.go => chat/chat.go} | 6 +- openapi/openapi.go | 6 +- 5 files changed, 628 insertions(+), 373 deletions(-) delete mode 100644 openapi/agent/README.md create mode 100644 openapi/chat/README.md rename openapi/{agent/agent.go => chat/chat.go} (95%) diff --git a/openapi/README.md b/openapi/README.md index 7f8c6d6a..838d19f3 100644 --- a/openapi/README.md +++ b/openapi/README.md @@ -271,37 +271,56 @@ The DSL Management API provides: All DSL endpoints require OAuth authentication. -## Agent API +## Chat API -Comprehensive API for AI agent interactions and chat completions with real-time streaming capabilities. +Comprehensive API for AI chat completions with **100% OpenAI client compatibility** and real-time streaming capabilities. -**[View Full Agent API Documentation →](agent/README.md)** +**[View Full Chat API Documentation →](chat/README.md)** -The Agent API provides: +The Chat API provides: +- **OpenAI Client Compatibility**: 100% compatible with existing OpenAI client libraries and SDKs - **Chat Completions**: AI-powered chat with streaming responses via Server-Sent Events - **Assistant Selection**: Multiple AI assistants with different capabilities and personalities +- **Standard Compliance**: Full OpenAI API specification compliance - **Context Management**: Persistent chat sessions with conversation history - **Real-Time Streaming**: Server-Sent Events for immediate response delivery -- **Session Management**: Automatic session handling with user identification -- **Flexible Parameters**: Configurable behavior for different client types and use cases +- **Dual Format Support**: Both OpenAI standard and Yao simplified parameter formats **Key Endpoints:** -- `GET /agent/chat/completions` - Stream chat completions with query parameters -- `POST /agent/chat/completions` - Stream chat completions with form data +- `GET /chat/completions` - Stream chat completions with query parameters (Yao format) +- `POST /chat/completions` - Stream chat completions with JSON body (OpenAI format) -**Features:** +**OpenAI Compatibility Features:** -- **Server-Sent Events**: Real-time streaming responses reduce latency -- **Multi-Assistant Support**: Choose from different AI assistants (`mohe`, `developer`, `analyst`, etc.) -- **Context Awareness**: Conversation history and additional context support -- **Silent Mode**: Configurable verbose/quiet response modes -- **Client Customization**: Client-type specific behavior and formatting +- **Zero Code Migration**: Existing OpenAI code works with just URL/token changes +- **Client Library Support**: Works with OpenAI Python, Node.js, Go, and other clients +- **Standard Response Format**: OpenAI-compatible streaming response structure +- **Parameter Compatibility**: Supports `model`, `messages`, `temperature`, `max_tokens`, etc. +- **Error Format**: OpenAI-compatible error response structure -**Note:** This is a temporary implementation for full-process testing, and the interface may undergo significant global changes in the future. +**Yao Extensions:** -All Agent endpoints require OAuth authentication. +- **Simplified Input**: Use `content` parameter for basic interactions +- **Assistant Selection**: Choose from Yao assistants (`mohe`, `developer`, `analyst`, etc.) +- **Context Awareness**: Additional context and conversation history support +- **Session Management**: Automatic session handling with user identification + +**Migration Example:** + +```python +# Before (OpenAI) +openai.api_key = "sk-..." + +# After (Yao - Only 2 lines change!) +openai.api_base = "https://your-yao.com/v1" +openai.api_key = "your-oauth-token" +``` + +**Note:** This is a temporary implementation for full-process testing, and the interface may undergo significant global changes in the future.
