| Description | Z.ai (formerly Zhipu AI) is a Beijing-based AI company that develops the open-source GLM family of large language models and offers them through an OpenAI-compatible API and a subscription-based GLM Coding Plan. It's aimed primarily at developers and startups who want Claude-class coding and agentic performance at roughly a tenth of the cost, alongside chat (ChatGLM/Qingyan), vision, image (CogView), and video (CogVideoX) generation. Its main differentiator is pairing genuinely competitive coding models with aggressive pricing and openly licensed weights. | ChatGPT by OpenAI is the world's most popular AI assistant with 200+ million weekly active users. From writing and coding to research and creative tasks, ChatGPT helps people get more done with conversational AI. |
