Which AI Model Should You Use? AI Model Families Explained

Every new AI model claims to be the best—but best at what? If you’re choosing between different AI model families, the newest and most powerful option may not be the right one for the job. As OpenAI and Anthropic release growing families of AI models, choosing the newest or most expensive option no longer guarantees the best result. Different models are now designed for complex reasoning, everyday work and high-volume routine tasks, and using the wrong one can waste money, consume your usage allowance and produce worse output. In this week’s episode, we explain how to choose the right AI model for each job, why model pricing affects the software your business uses, and what cached context and benchmark scores actually tell you. We also discuss the different strengths of Claude and ChatGPT, before looking at OpenAI Dots and Meta's Muse, the new personal AI agents competing for access to your email, calendar and business tools.
