⚖️ Pros & Cons
🧠 Claude
- Best writing quality on the market — Opus 4.6 excels at long-form, nuanced editorial content including in French
- Claude Code revolutionizes development — an autonomous coding agent capable of modifying an entire project
- The model that hallucinates the least — among the lowest hallucination rates thanks to Anthropic's constitutional safety
- MCP (Model Context Protocol) — an open integration ecosystem growing fast, connected to GitHub, Slack, databases and more
- Memory and Research mode — persistent conversations and built-in multi-source deep research
- No image or video generation — unlike ChatGPT (DALL-E, Sora) and Gemini (Imagen, Veo)
- Free tier is limited — severe message reduction during peak hours
- No native web search on the free tier — Research mode requires a Pro subscription
🐋 DeepSeek
- Open-source MIT and self-hostable — run the model on your own servers without sending any data to China
- Reasoning and code performance comparable to the best — at up to 30x lower API cost
- Completely free online — no known message limits on the official website
- Multiple model sizes available — from a small model for a laptop to a large model for datacenters
- Innovative MoE (Mixture of Experts) architecture — remarkable efficiency delivering high performance with fewer resources
- Data stored on Chinese servers — banned in Italy and Germany for GDPR violations, major risk for Europeans
- Documented security flaws — database publicly exposed and jailbreak rate among the highest on the market
- Automatic censorship on politically sensitive topics in China — government-imposed limits
🏆 Verdict
🧠 Choose Claude
The best model for writing, code and analysis. Opus 4.6 and Claude Code make it the top choice for demanding developers and writers. The MCP protocol opens an ecosystem catching up to ChatGPT's.
🐋 Choose DeepSeek
Best performance/price ratio on the market for reasoning and code, with a self-hostable model. Ideal for devs who can self-host. Direct use via deepseek.com is a major privacy risk for Europeans.
