A request can fail at three moments: before you send it, while it runs, or after it returns. Different tools and habits cover different moments. This is a directory grouped by what each one does. Methods you apply yourself You apply these for free, and they rule out several common failures before you reach for a tool. Pick the model that fits the request. A small fast model handles simple calls, and a larger one handles reasoning. One model for
