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
OpenAI Agents SDK
- +Minimal, low-abstraction framework that is quick to learn
- +Built-in handoffs, guardrails, sessions, and tracing
- +Provider-agnostic (100+ LLMs) with Python and JS/TS (and voice) SDKs
- -A framework, not a product: you build, host, and secure the agent yourself
- -Autonomy and safety depend entirely on how the developer configures it
