 def track_me(v):
     return v + 5
 
-weave.init()
+weave.init('add5-GPT')
 track_me(15)
 ```
 
 Calling an op will created a new op version if the code has changed from the last call, and log the inputs and outputs of the function.
 
 :::note
-Functions decorated with `@weave.op()` will behave normally (without code versioning and tracking), if you don't call `weave.init()` before calling them.
