Trying various models outside of examples given in TVM

I wanted to try graphs/models outside of the list given in the TVM tutorials.
https://docs.tvm.ai/tutorials/index.html

Could anyone suggest me some examples outside the tutorial’s models ?

Also, in the Relay API , some functions seem to suggest we can compile all graphs from ONNX/ tensorflow/ keras etc. frontends, if we can convet them into relay graphs. Can it be validated ?
https://docs.tvm.ai/api/python/relay/frontend.html#tvm.relay.frontend.from_coreml

What support does TVM Relay API provide for, say , ONNX and tensorflow graphs that are constantly changing opeators, or some complex control flows in graphs .
