Frequently asked questions
Claude or Grok: which is cheaper?
Grok is overall cheaper ($2 per 1M input tokens, $10 per 1M output) than Claude ($3 input, $15 output). The real cost depends on your input/output ratio: heavy output use widens the gap in favor of the cheaper one.
Claude or Grok: which is better for code?
Claude is generally preferred for code by developers in 2026: structured output, few hallucinations, good comments. Grok remains a fair choice depending on context (budget, integrations).
Claude or Grok: which is GDPR-friendly?
Neither Claude nor Grok is European. Both provide GDPR-compliant Data Processing Agreements (DPA), but data transits through the US (or China for DeepSeek). For full sovereignty, Mistral AI remains the European reference.
What's the context window for Claude vs Grok?
Claude accepts 200K tokens of context, Grok 256K. Grok has the larger window, which matters for analyzing long documents (books, dossiers, codebases) in one request.
