genai sdk vs adk #ai #genai #coding

This content compares two approaches for building with Google's AI models: the Gen AI SDK, which provides direct model access (like calling Gemini) with custom logic handling, versus the ADK (Agent Development Kit), which offers a higher-level framework for building AI agents. The distinction highlights the trade-off between low-level control and abstraction.

Key Points

• •Gen AI SDK is a model client that provides direct access to Gemini and other models
• •With Gen AI SDK, you call the model directly and receive responses without built-in orchestration
• •Gen AI SDK requires you to write custom logic around model calls for handling responses
• •ADK (Agent Development Kit) is a higher-level abstraction built on top of model clients
• •ADK provides framework-level features for agent development, reducing boilerplate code
• •Choose Gen AI SDK for fine-grained control and custom workflows
• •Choose ADK for faster agent development with pre-built patterns and abstractions
• •Gen AI SDK is lower-level; ADK is higher-level with more opinionated structure
