Frequently asked questions
GPT or Mistral: which is cheaper?
Mistral is overall cheaper ($2 per 1M input tokens, $6 per 1M output) than GPT ($2.5 input, $10 output). The real cost depends on your input/output ratio: heavy output use widens the gap in favor of the cheaper one.
GPT or Mistral: which is better for code?
GPT is generally preferred for code by developers in 2026: structured output, few hallucinations, good comments. Mistral remains a fair choice depending on context (budget, integrations).
GPT or Mistral: which is GDPR-friendly?
Mistral (built by Mistral AI, EU-based) offers stronger native GDPR alignment than GPT. For EU enterprise use with sensitive data, Mistral is usually the default.
What's the context window for GPT vs Mistral?
GPT accepts 128K tokens of context, Mistral 128K. Mistral has the larger window, which matters for analyzing long documents (books, dossiers, codebases) in one request.
