Question 1

How much VRAM does Qwen2.5-3B-Instruct need?

Accepted Answer

Qwen2.5-3B-Instruct (3.1B) requires approximately 6.897610473632812 GB of VRAM at full precision (FP16), 3.4 GB at 8-bit quantization (Q8), and 1.7 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 Qwen2.5-3B-Instruct?

Accepted Answer

We have 10 compatible GPUs indexed for Qwen2.5-3B-Instruct, including L4, M60, RTX A4000, T4, A40 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 Qwen2.5-3B-Instruct?

Accepted Answer

The cheapest GPU to run Qwen2.5-3B-Instruct in the cloud is the L4 at $0.20/hr. Other affordable options include M60 ($0.23/hr) and RTX A4000 ($0.25/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can Qwen2.5-3B-Instruct run on consumer hardware?

Accepted Answer

Yes, Qwen2.5-3B-Instruct can run on consumer GPUs like the RTX A4000 (16 GB VRAM) at full precision (FP16). Other compatible consumer GPUs include RTX 3090 and RTX A4500.

Question 5

What quantization options are available for Qwen2.5-3B-Instruct?

Accepted Answer

Qwen2.5-3B-Instruct supports the following quantization levels: FP16 (full precision): ~6.897610473632812 GB, Q8 (8-bit): ~3.4 GB, Q6 (6-bit): ~2.6 GB, Q4 (4-bit): ~1.7 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.
