Question 1

How much VRAM does bloomz need?

Accepted Answer

bloomz (176.2B) requires approximately 393.94335021972654 GB of VRAM at full precision (FP16), 197 GB at 8-bit quantization (Q8), and 98.5 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 bloomz?

Accepted Answer

We currently have no compatible GPUs indexed for bloomz. This may be because the model's VRAM requirements exceed available GPUs in our database, or VRAM data hasn't been computed yet.

Question 3

What is the cheapest GPU to run bloomz?

Accepted Answer

We don't currently have cloud pricing data for GPUs compatible with bloomz. Cloud pricing data is updated regularly — check back soon.

Question 4

Can bloomz run on consumer hardware?

Accepted Answer

bloomz requires approximately 393.94335021972654 GB of VRAM at FP16, and even with 4-bit quantization (Q4) it needs about 98.5 GB. This exceeds the 24 GB available on the highest-end consumer GPU (RTX 4090), so bloomz requires datacenter or cloud GPUs.

Question 5

What quantization options are available for bloomz?

Accepted Answer

bloomz supports the following quantization levels: FP16 (full precision): ~393.94335021972654 GB, Q8 (8-bit): ~197 GB, Q6 (6-bit): ~147.7 GB, Q4 (4-bit): ~98.5 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.
