ChatGPT
The chatbot that started the AI revolution. GPT-5.5 'Spud' launched 2026-04-23 -- SOTA agentic coding (Terminal-Bench 2.0 82.7%), 84.9% GDPval, 1M context. ChatGPT Images 2.0 / gpt-image-2 (2026-04-21) brings native-reasoning image gen + 8-image continuity
ChatGPT is the Toyota Camry of AI chatbots. It's not the flashiest or the absolute best at any one thing, but it does everything well, it's reliable, and the ecosystem around it is massive. With GPT-5.5 'Spud' now live (2026-04-23), ChatGPT pulls ahead on agentic coding (Terminal-Bench 82.7%) and long-context (MRCR 74% at 512K-1M, +37pt jump) -- upgrade if you do either. Hold on Free tier (GPT-5.5 excluded) or if you're API-dependent (API 'coming soon', not live at launch). For most people, this is still the only AI chatbot they need.
