Models Overview - Chatgpt On Wechat

CowAgent supports mainstream large language models from both Chinese and overseas vendors. Model interfaces are implemented under the project's models/ directory. In addition to text chat, some vendors also provide vision understanding, image generation, speech-to-text, text-to-speech, and embedding capabilities, which can be invoked on demand in the Agent flow.

<Note> The following models are recommended in Agent mode; choose based on quality and cost: deepseek-v4-flash, MiniMax-M2.7, claude-sonnet-4-6, gemini-3.5-flash, glm-5.1, qwen3.6-plus, kimi-k2.6, ernie-5.1.

LinkAI is also supported, letting you switch between multiple vendors with a single key while gaining knowledge bases, workflows, and plugins. </Note>

<Tip> Every capability in the Web Console (Vision / Image / Speech-to-Text / Text-to-Speech / Embedding / Web Search) can be configured independently with its own vendor and model; they are not forced to be bound together. </Tip>

How to Configure

Option 1 (recommended): Manage models and capabilities online via the Web Console, with no need to edit the configuration file:

Option 2: Manually edit config.json and fill in the model name and API key according to the selected model. Every model also supports OpenAI-compatible access: set bot_type to openai and configure open_ai_api_base and open_ai_api_key.
