I know the scaled_dot_product_attention of torch.nn.functional does not and it is a big problem for me. Does FlexAttention support batched mode?

@MiladInk We haven't added support yet but it shouldn't be too hard. I've also been meaning to add vmap support for scaled_dot_product_attention... might do it this weekend.

btw, we just added vmap support for scaled_dot_product_attention: pytorch/pytorch#133964

We'll also look into doing it for FlexAttention soon.
