ChatGPT propose un plan gratuit et des offres payantes. Free: $0 — access to current models with usage limits, web search, and basic data analysis. Go: $8/month — ~10x the messages, image generation, and uploads of Free, plus longer memory and context. Plus: $20/month — GPT-5.5, higher message limits, deep research, agent mode, Sora video generation, advanced voice, and early feature access. Pro: $200/month — near-unlimited GPT-5.5 access including GPT-5.5 Pro, the largest context and memory, and the earliest previews of new capabilities. Business (formerly Team): $25/user/month, or $20/user/month billed annually (2+ seats) — a shared workspace, admin controls, and no training on your business data. Enterprise: custom pricing.
