"Vercel AI SDK - how do I get ai to interpret the tools response?" 👇

I usually just set up maxSteps to be infinity. Is it a bad practice?

Could lead to infinite loops according to the docs.

Stay competitive by balancing cutting-edge AI with automation tools. Forrester shows how.

So, does it mean maxStep is required for Tool Calling?

Nope. If you just need the tool's call result (e.g., displaying the weather widget with data from the weather API), you can directly access it from message.toolInvocations (no need for maxSteps) It's when you need to feed the result of the tool invocation back to LLM for it to interpret and respond that's when you need maxStep

Why does it not work without maxSteps?

It does work, the tool gets called, and you have access to its result in your UI. But if you want to feed the tool's invocation result back to llm to get natural language response, you need more steps
