ChatGPT Agent
- +Unifies browsing (Operator) and analysis (Deep Research) into one agent
- +Acts on a virtual computer: browses, runs code, and builds deliverables
- +Available across ChatGPT paid plans with no separate product to adopt
- -Agentic browsing can be slow and error-prone on complex sites and login/CAPTCHA flows
- -Requires user oversight; not a hands-off autonomous worker
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
