Free vs paid AI: what's the difference?
Free versions of consumer AIs (ChatGPT, Gemini, Claude.ai, Mistral Le Chat) give access to a downgraded model (often the mini/flash variant) with tight quotas: 10-50 requests per day, no long history, no attachments, no API. Paid versions unlock: the flagship model (Claude Sonnet, GPT-4o, Gemini 2.
Free versions of consumer AIs (ChatGPT, Gemini, Claude.ai, Mistral Le Chat) give access to a downgraded model (often the mini/flash variant) with tight quotas: 10-50 requests per day, no long history, no attachments, no API. Paid versions unlock: the flagship model (Claude Sonnet, GPT-4o, Gemini 2.5 Pro), much higher quotas, file upload (PDF, images), persistent history, access to premium features (image generation, voice mode, web browsing). For occasional use (1-10 questions/day), free is plenty. For productive use, paid becomes necessary. Three paid models exist: (a) $20/month subscription (ChatGPT Plus, Claude Pro, Gemini Advanced) — good if you saturate one subscription, bad if you mix models; (b) direct API access via each vendor's developer portal; (c) pay-as-you-go aggregator platforms like Ask Aurel with top-up from €10 — ideal for moderate use or to compare multiple models without locking in.
