jit cache key should include device (really, device type)

from jax import device_put, devices, jit
import jax.numpy as np
import numpy as onp

def f(x):
    return np.sum(x)

f0 = jit(f, device=devices()[0])
f1 = jit(f, device=devices()[1])

data = onp.random.rand(10000)

x0 = device_put(data, device=devices()[0])
x1 = device_put(data, device=devices()[1])

print("f on gpu 0:", f0(x0))
print("f on gpu 1:", f1(x1))

As I run this code on my machine, there are errors like this

f on gpu 0: 4949.328

Could you give me some advice?
