I had the same issue with Benchee - I saw someone mention in the elixir forum that Benchee was crashing the LiveBook cells a while back. I’m also on Apple Silicon - LiveBook v0.9.3, Elixir v1.14.2.

I was curious so:  
{exla\_time, exla\_result} = :timer.tc(fn →   
apply(EXLA.jit(&Softmax.softmax/1), [tensor])  
end)

{standard\_time, standard\_result} = :timer.tc(fn →   
Softmax.softmax(tensor)  
end)

IO.puts “exla is #{standard\_time/exla\_time} times faster”  
result (one run):  
exla is 66.25130208333333 times faster

On multiple runs its between 450 and 500 times faster.
