 Models, like any other Redis and RedisAI data structures, are identified by keys. A Model's key is created using the [`AI.MODELSET` command](commands.md#aimodelset) and requires the graph payload serialized as protobuf for input.
 
-In our examples, we'll use one of the graphs that RedisAI uses in its tests, namely 'graph.pb', which can be downloaded from [here](https://github.com/RedisAI/RedisAI/raw/master/tests/test_data/graph.pb). This graph was created using TensorFlow with [this script](https://github.com/RedisAI/RedisAI/blob/master/tests/test_data/tf-minimal.py).

 ??? info "Downloading 'graph.pb'"
     Use a web browser or the command line to download 'graph.pb':
 
     ```
-    wget https://github.com/RedisAI/RedisAI/raw/master/tests/test_data/graph.pb
+    wget https://github.com/RedisAI/RedisAI/raw/master/tests/flow/test_data/graph.pb
     ```
 
 You can view the computation graph using [Netron](https://lutzroeder.github.io/netron/), which supports all frameworks supported by RedisAI.
