OpenAI's flagship AI chatbot with the largest mainstream user base. GPT-5.x models for chat, search, image generation, voice, code interpreter, and agent workflows.
ChatGPT is OpenAI's flagship consumer AI product, launched in late 2022 and now used by hundreds of millions of people weekly. As of May 2026, the default model is GPT-5.x, with high-reasoning variants (gpt-5.4-high, gpt-5.5-high) regularly placing in the LMArena Chatbot Arena top 10 alongside Claude Opus and Gemini 3. The product bundles several capabilities beyond chat. Web search returns live citations. Image generation (current DALL-E successor) creates photo-quality images from text. Code Interpreter runs Python sandboxed for data analysis and plotting. Advanced Voice Mode supports natural, low-latency conversation. The Agent feature lets ChatGPT browse, click, and complete multi-step tasks autonomously — still early but improving rapidly. Pricing has tiers. Free users get GPT-5 access with daily caps. Plus ($20/mo) raises limits, adds priority access during peaks, and unlocks advanced
earlier. Pro ($200/mo) offers near-unlimited use of the strongest models for power users. Team and Enterprise add admin controls, longer context, and data-handling guarantees. Where ChatGPT wins: distribution and habit (everyone has it), multimodal breadth (text + image + voice + agent in one product), and the broadest ecosystem of custom GPTs and integrations. Where it lags: coding quality vs Claude on hard problems, and pricing transparency (the API and ChatGPT product are priced and behave differently).
