DeepSeek AI review

DeepSeek AI provides frontier-class performance at significantly lower costs than competitors, although businesses face serious privacy concerns. Meanwhile, Duck.ai by DuckDuckGo offers private AI chat without requiring logins. This service includes six free models and paid tiers that grant access to advanced options such as GPT-5.4 and Claude Opus 4.7. Both platforms present distinct trade-offs between high-end AI capabilities, pricing structures, and the level of user data privacy provided to consumers.
