What is ChatGPT?
ChatGPT is OpenAI's conversational AI assistant, launched in November 2022. The free tier offers access to GPT-5 with rate limits; the Plus plan ($20/month) raises limits and adds priority access to new models, advanced voice mode, image generation via DALL-E 3, and custom GPTs. The Pro plan ($200/month) adds o1-pro reasoning, larger context windows, and effectively unlimited use.
ChatGPT supports text, voice, image input/output, code execution, web search, and file analysis. The 128K context window on GPT-4o handles long documents. Custom GPTs let users build no-code AI assistants for specific tasks. The API (priced separately) starts at $0.15/M input tokens for GPT-4o-mini.
Main limitations: knowledge cutoff lags by a few months; hallucinations happen on edge facts; the Plus plan caps messages per 3-hour window; the Pro plan's $200/month is steep for casual use. Team and Enterprise plans add SSO, admin controls, and SOC 2.
