zhipu_ai_api_key enables all capabilities.

Image Understanding
glm-5.3-flash is natively multimodal, so when it is the main model the Agent’s Vision tool uses it directly. Text-only chat models (glm-5.2, glm-5.1, glm-5-turbo, etc.) do not support vision; for those, vision calls automatically fall back to the dedicated glm-5v-turbo model. Once zhipu_ai_api_key is configured, no extra setup is needed.
