DeepSeek
DeepSeek is the Chinese lab that upended AI pricing with frontier-class reasoning and coding models at a fraction of Western costs. Its consumer chat app is free, and the DeepSeek API is among the cheapest anywhere, with an OpenAI-compatible interface and open-weight model releases developers can self-host. Models in its V-series and reasoning line are genuinely strong on math, code, and logic. The trade-off is China jurisdiction and data-governance concerns that matter for Western businesses.
You.com
You.com began as a web-grounded, citation-first AI search engine and has pivoted hard toward enterprise and agentic search APIs. As of April 2026 the old unlimited consumer free tier is effectively gone -- free users get a ~25-query Pro trial, with Pro at $20/mo and Max at $200/mo. The real strength now is the developer side: Search, Contents, and Research APIs with $100 in free credits, a free MCP endpoint (100 queries/day) for Claude Code and Cursor, SOC 2 certification, and no training on your data. It's a strong choice for building RAG and agents, less so as a casual consumer chatbot.
DeepSeek edges You.com on aggregate — 88 vs 78.
Frontier-class reasoning and coding at rock-bottom prices, with open weights -- held back for Western firms only by China-hosting and compliance concerns. You.com still wins for buyers who prioritise best-in-class web-grounded, cited answers (rag-ready). Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
