Pros	Context is treated like source code with structured assembly of sessions, memory, tool outputs, and artifacts, automatic filtering of irrelevant events, summarization of older turns, lazy-loading of artifacts, and token usage tracking to keep agents fast, efficient, and reliable by default Multi-language support with Python, TypeScript, Go, and Java implementations Model-agnostic and compatible with other frameworks while optimized for Gemini Built-in development UI for testing, evaluating, debugging, and showcasing agents When deploying to Google Cloud, agents inherit managed infrastructure, built-in authentication, Cloud Trace observability, and enterprise-grade security without code changes	True data sovereignty—sensitive enterprise data stays on-premises, never routed through vendor clouds Model agnostic—swap between commercial (OpenAI, Anthropic), open-source, and local models without application refactor Production-grade RAG and orchestration via Haystack on day one, not a stub Multi-platform native support (Windows, macOS, Linux, iOS, Android) from launch Open-source under permissive MPL 2.0 license; auditable and customizable by default
Cons	Optimized primarily for Google Cloud deployment and Gemini models, though model-agnostic capabilities exist Development version builds directly from latest code commits may contain experimental changes or bugs not present in stable release	Early-stage product under active development and mid-security audit; not yet production-ready for regulated buyers Organizations bear full responsibility for self-hosted deployment, patching, hardening, access control, and monitoring Requires DevOps expertise; not designed for ease-of-use like managed competitors (Copilot, ChatGPT Enterprise)
