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
Microsoft Copilot
- +Deepest integration into tools people already live in, grounded in org data via Microsoft Graph
- +A genuine agent platform with open MCP and A2A interop and multi-model choice (OpenAI, Anthropic, in-house)
- +Enterprise-grade controls, with licensed-user agent usage zero-rated in M365 apps
- -Layered, confusing pricing: the $30 seat is an add-on on top of a base license, and agents bill in separate credits that were renamed in 2025
- -The flagship in-app experience is assistant/copilot, not autonomous, so agent marketing can overstate it
