TapeAgents are like helpful robots that can do tasks for you, like searching the web or filling out forms. TapeAgents use a special list, called a "tape," to keep track of everything they do and think. Imagine it like a notebook where they write down their plans, actions, and observations. TapeAgents can work alone or in teams, and they can even learn from their past experiences (the tapes) to get better at their jobs. For example, the sources discuss a TapeAgent that learned how to fill out forms correctly by studying examples from a "teacher" TapeAgent that used a really big and powerful brain (a large language model). This allows companies to build helpful AI assistants that are cheaper and faster to run. You can see examples of how TapeAgents work in Figures 3 and 5, which show the "tapes" they create while working on different tasks.
