Question 1

How much VRAM does Spatial-SSRL-Qwen3VL-4B need?

Accepted Answer

Spatial-SSRL-Qwen3VL-4B (4.8B) requires approximately 10.788676071166991 GB of VRAM at full precision (FP16), 5.4 GB at 8-bit quantization (Q8), and 2.7 GB at 4-bit quantization (Q4). The actual VRAM usage may be slightly higher due to KV cache and runtime overhead.

Question 2

What GPUs can run Spatial-SSRL-Qwen3VL-4B?

Accepted Answer

We have 10 compatible GPUs indexed for Spatial-SSRL-Qwen3VL-4B, including K80, L4, A40, A100 40GB, A10G and 5 more. Compatibility is determined by whether the GPU's VRAM can fit the model's memory footprint, potentially using quantization to reduce memory usage.

Question 3

What is the cheapest GPU to run Spatial-SSRL-Qwen3VL-4B?

Accepted Answer

The cheapest GPU to run Spatial-SSRL-Qwen3VL-4B in the cloud is the K80 at $0.18/hr. Other affordable options include L4 ($0.20/hr) and A40 ($0.44/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can Spatial-SSRL-Qwen3VL-4B run on consumer hardware?

Accepted Answer

Yes, Spatial-SSRL-Qwen3VL-4B can run on consumer GPUs like the RTX A6000 (48 GB VRAM) at full precision (FP16).

Question 5

What quantization options are available for Spatial-SSRL-Qwen3VL-4B?

Accepted Answer

Spatial-SSRL-Qwen3VL-4B supports the following quantization levels: FP16 (full precision): ~10.788676071166991 GB, Q8 (8-bit): ~5.4 GB, Q6 (6-bit): ~4 GB, Q4 (4-bit): ~2.7 GB. Lower quantization reduces VRAM usage at the cost of some quality loss. Q8 offers a good balance between quality and memory savings, while Q4 provides maximum compression.
