Streaming: Replace generateContent with streamGenerateContent in the URL to enable streaming responses, receiving content in real-time chunks.
BaseURL: The default BaseURL is https://direct.evolink.ai, which has better support for text models and long-lived connections. https://api.evolink.ai is the primary endpoint for multimodal services and serves as a fallback address for text models.
