DeepSeek stores data in China under Chinese law. Use caution with sensitive information.
What are ChatGPT limitations in 2026?
ChatGPT still has knowledge cutoffs, hallucination issues, and a smaller context window than Claude.
What are Claude limitations?
Claude cannot generate images, browse the web, or run code natively. It also has strict usage limits.
What are Gemini limitations?
Gemini struggles with creative writing consistency and occasionally produces less accurate responses than competitors.
What are Grok limitations?
Grok trails in reasoning depth and has a smaller ecosystem than ChatGPT or Claude.
Will AI replace programmers?
No, but AI is transforming programming. Developers who use AI tools are significantly more productive.
