There is no single best AI model for long. Each one is strong at different jobs, the leaders change every few months, and many people already use two or three. The useful question is which model fits a task today, and what it costs you to change your mind.
These guides compare assistants on the work people actually do: writing, research, analysis, coding and planning. They point to each vendor's own pages for plans and limits, because those change often. They also cover the hidden cost of choosing: the chat history, memory and project setup that stay behind in the app you leave.
fenbs keeps the work outside any one model. Projects, tasks, Decisions and rules and Where we left off stay in one place that Claude, ChatGPT, Gemini CLI, Cursor and others can read, so trying a new model is cheap.
The first guides in this topic are coming soon.
