DeepSeek
- +Free consumer chat assistant and a notably low-cost API versus US frontier providers
- +Open-weight models under the MIT license, so they can be self-hosted, fine-tuned, and run by third parties
- +OpenAI- and Anthropic-compatible API makes it a near drop-in for existing apps and coding tools
- -It is an assistant, not an autonomous agent: it responds when asked and does not act end-to-end
- -China-hosted service raises data-residency and privacy concerns, and the app has faced government bans and scrutiny in several countries
Google Agent Development Kit (ADK)
- +Backed by Google with first-class deployment to Vertex AI and Cloud Run
- +Built around the open A2A protocol for cross-framework agent interoperability
- +Model-agnostic via LiteLLM despite Gemini-first defaults
- -A framework, not a product: you build, host, and secure agents yourself
- -Strongest when paired with Google Cloud, which can imply lock-in
