AI model guides

Independent guides to AI models

New AI assistants and model versions appear constantly, and the names can be confusing. These guides explain the best-known AI model families in plain language: who makes each one, what it is typically good at, where it falls short, how to use it through its official apps and websites, and what to know about privacy.

The guides are written independently. ChatG is not affiliated with any of these companies, nothing here is sponsored, and the guides do not describe ChatG itself. To use one of these products, go to its maker's official site or app, which each guide names.

The model families we cover

• ChatGPT, the assistant from OpenAI, built on its GPT models.
• Claude, the family of models and assistant from Anthropic.
• Gemini, Google's family of models and its assistant app.
• DeepSeek, models and a chat app from the Chinese company DeepSeek.
• Grok, the assistant from xAI.
• Llama, Meta's family of models.
• Qwen, the model family from Alibaba.
• Mistral, models from the French company Mistral AI.

Some of these makers mainly offer their models through their own apps and paid plans, while others have also released open-weight models that developers can download and run themselves. Each guide explains how access works for that family.
