ChatGPT
- +Broadest, most capable consumer AI assistant: chat, voice, image, search, files, and code in one place
- +Generous free tier plus a clear ladder of paid plans (Go, Plus, Pro, Business, Enterprise)
- +Agentic surfaces (deep research, agent mode) layered on top for users who need multi-step work
- -Mostly an assistant: the base product responds when asked rather than acting autonomously
- -Best agentic and reasoning features are gated to higher-priced paid tiers
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
