⚖️ Pros & Cons
🤖 ChatGPT
- Most complete ecosystem on the market — text, images, video (Sora), voice, agents (Operator) and projects all in one interface
- GPT-5.2 Thinking reasoning accessible from the Plus plan at ~$20/mo — step-by-step complex problem solving
- Persistent memory and projects — the AI retains context between conversations and organizes work by project
- Massive community — millions of users guarantee tutorials, templates and support everywhere
- The Swiss army knife of AI — the default tool when you only want a single subscription
- User data used for training by default — the opt-out option exists but is buried in settings
- Free tier now includes ads — degraded experience and fallback to a less capable model during peak hours
- Pro subscription at ~$200/mo — the most advanced features remain reserved for big budgets
🐋 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 ChatGPT
The Swiss army knife of AI: best-in-class in ecosystem and versatility with Sora, Operator and GPT-5.2. The default choice for anyone wanting a single tool, but configure your privacy settings carefully and note the ads on the free tier.
🐋 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.
