From the FAQ[1]:

> Can Bard help with coding?

> Bard can’t help you with coding just yet. Bard is still learning to code, and responses about code aren’t officially supported for now.

A little disappointing.

Edit: Ah, on the blog post, they mention they are using their smaller model initially:

> We’re releasing it initially with our lightweight model version of LaMDA. This much smaller model requires significantly less computing power, enabling us to scale to more users, allowing for more feedback.

I wonder how much better the larger model is…
