Question 1

How much VRAM does bloom-1b1 need?

Accepted Answer

bloom-1b1 (1.1B) requires approximately 2.3811630249023437 GB of VRAM at full precision (FP16), 1.2 GB at 8-bit quantization (Q8), and 0.6 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 bloom-1b1?

Accepted Answer

We have 10 compatible GPUs indexed for bloom-1b1, 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 bloom-1b1?

Accepted Answer

The cheapest GPU to run bloom-1b1 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 bloom-1b1 run on consumer hardware?

Accepted Answer

bloom-1b1 may be able to run on high-end consumer GPUs like the RTX 4090 (24 GB) with 4-bit quantization (Q4), which reduces VRAM usage to approximately 0.6 GB. However, performance may be limited compared to datacenter GPUs.

Question 5

What quantization options are available for bloom-1b1?

Accepted Answer

bloom-1b1 supports the following quantization levels: FP16 (full precision): ~2.3811630249023437 GB, Q8 (8-bit): ~1.2 GB, Q6 (6-bit): ~0.9 GB, Q4 (4-bit): ~0.6 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.
