Claude
- +Strong writing, reasoning, and coding plus interactive Artifacts in one assistant
- +Open MCP Connectors wire it into Gmail, Workspace, Slack, Jira, and Zapier

- -Most of the product is assistant/copilot grade; the agentic modes are newer and narrower
- -Cowork ships as a research preview and (for now) on the desktop app
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
