Questions About smolvla-policy

How much GPU memory does smolvla-policy need?

About 1.1 GB at 16-bit and 0.3 GB at 4-bit: the weights (450M parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run smolvla-policy on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

Can I use smolvla-policy commercially?

Yes. smolvla-policy is released under Apache License 2.0. The Apache License 2.0 is a permissive open-source license. It permits commercial use, modification and redistribution. It requires keeping the license and copyright notices and any NOTICE file, stating significant changes, and it includes an express patent grant from contributors.
