OpenAI Agents SDK
- +Minimal, low-abstraction framework that is quick to learn
- +Built-in handoffs, guardrails, sessions, and tracing

- -A framework, not a product: you build, host, and secure the agent yourself
- -Autonomy and safety depend entirely on how the developer configures it
Vercel AI SDK
- +De facto standard for building AI features in TypeScript, with a large ecosystem and strong docs
- +Genuinely provider-agnostic: swap models behind one clean API
- +Excellent streaming and generative-UI integration, especially with Next.js
- -TypeScript/JavaScript only; no Python support
- -Agent orchestration is lighter than dedicated multi-agent frameworks
