CowAgent supports a wide range of mainstream large language models. Model interfaces live under the project’s models/ directory. Beyond text chat, several providers also provide vision understanding, image generation, speech-to-text, text-to-speech, and embeddings — all of which can be invoked on demand in the Agent flow.
Capability Matrix
A snapshot of each provider’s capabilities. “Text” refers to the main chat model; the remaining columns show which Agent capabilities the provider can power.
Every capability in the Web console (Vision / Image / STT / TTS / Embedding / Web Search) can be configured independently with its own provider and model — there is no forced binding between them.
Option 2: Edit config.json manually and fill in the model name and API key for the selected provider. Every model also supports OpenAI-compatible access — just set bot_type to openai and configure open_ai_api_base and open_ai_api_key.
