Question 1

How much VRAM does Ising-Calibration-1.5-31B-BF16 need?

Accepted Answer

Ising-Calibration-1.5-31B-BF16 (31.3B) requires approximately 69.90080075562 GB of VRAM at full precision (FP16), 35 GB at 8-bit quantization (Q8), and 17.5 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 Ising-Calibration-1.5-31B-BF16?

Accepted Answer

We have 10 compatible GPUs indexed for Ising-Calibration-1.5-31B-BF16, including RTX Pro 6000 Blackwell, A100 80GB PCIe, A100 80GB, H100 MEGA, H100 SXM 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 Ising-Calibration-1.5-31B-BF16?

Accepted Answer

The cheapest GPU to run Ising-Calibration-1.5-31B-BF16 in the cloud is the RTX Pro 6000 Blackwell at $1.10/hr. Other affordable options include A100 80GB PCIe ($1.39/hr) and A100 80GB ($1.39/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can Ising-Calibration-1.5-31B-BF16 run on consumer hardware?

Accepted Answer

Yes, Ising-Calibration-1.5-31B-BF16 can run on consumer GPUs like the RTX Pro 6000 Blackwell (96 GB VRAM) at full precision (FP16).

Question 5

What quantization options are available for Ising-Calibration-1.5-31B-BF16?

Accepted Answer

Ising-Calibration-1.5-31B-BF16 supports the following quantization levels: FP16 (full precision): ~69.90080075562 GB, Q8 (8-bit): ~35 GB, Q6 (6-bit): ~26.2 GB, Q4 (4-bit): ~17.5 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.
