[43] presents variational score distillation to construct mul-
tiple particles for a single prompt input, sampling the op-
timal 3D representation from the corresponding probabilis-
tic distribution. These works mainly focus on optimizing
an implicit 3D representation for a prompt. Given a new
prompt, they need to repeat the optimization process, tak-
ing more than one hour. In contrast, our Instant3D is able
to generate a high-quality 3D object for a new prompt in
less than one second after training.
