## Runs On

What it takes to serve Alpamayo-1.5-10B (11.1B parameters): the memory its weights need at each precision, and the cheapest way to rent enough data-center GPUs to hold them.

Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the [SAVRN Index](https://savrn.com/ai-index/pricing/gpus), read Oct 23, 2026.

## Questions About Alpamayo-1.5-10B

### How much GPU memory does Alpamayo-1.5-10B need?

About 26.6 GB at 16-bit and 6.6 GB at 4-bit: the weights (11.1B parameters) plus a working margin. A long context needs more.

### What is the cheapest GPU to run Alpamayo-1.5-10B 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.

### What license is Alpamayo-1.5-10B released under?

openmdw-1.1, as its publisher declares it. Read the license text before commercial use.

OpenVLA 7B (openvla-7b) is an open vision-language-action model trained on 970K robot manipulation episodes from the Open X-Embodiment dataset. The model takes language instructions and camera images as input and generates robot actions. It supports controlling multiple robots out-of-the-box, and can be quickly adapted for new robot domains via (parameter-efficient) fine-tuning. All OpenVLA checkpoints, as well as our training codebase are released under an MIT License. For full details, please read our paper and see our project page.
