As AI models continue to evolve, they are beginning to give us different products for different kinds of use cases. The three products I find most useful are: - Chat - Work - Code There are also specialized products for things such as design, research, and working with source material—including tools like Claude Design, Gemini Notebook. But for today, let’s stick with the three horsemen: Chat, Work, and Code. Each AI company is known for its models. The large, well-known models—ChatGPT, Claude, and Gemini—are commonly referred to as frontier models and are generally associated with closed, cloud-based systems rather than open-source models running locally. Please refer to the "Frontier AI Ecosystem Matrix" to see what OpenAI, Anthropic, Google, Microsoft, xAI, and Perplexity call their respective models and products. For this series, I will use the follow product naming convention: - Chat - (Co)Work - Code(x) The parentheses are simply my shorthand to cover the names used by ChatGPT and Claude. Please note that these are not official industry terms. They simply save me from repeatedly writing “Work or Cowork” and “Code or Codex.” LOL! Here is the easiest way I have found to explain the difference between the products: Chat: What question can I answer for you, right now? (Co)Work: What can I take off your plate? Code(x): What can I build for you? The goal is not to create a perfect technical definition. It is to give you a simple way to recognize which type of AI product may be the best fit for the task in front of you. In Part 2, we will look more closely at Chat, (Co)Work, and Code(x) product features, how each product is actually used and where the lines between products overlap. In Part 3, we will work through a few practice exercises to help solidify the use cases for each product. If you have any questions, please ask in the comments below. Make it a great AI day!
