Question 1

How much VRAM does falcon-40b-instruct need?

Accepted Answer

falcon-40b-instruct (40B) requires approximately 89.40696716308594 GB of VRAM at full precision (FP16), 44.7 GB at 8-bit quantization (Q8), and 22.4 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 falcon-40b-instruct?

Accepted Answer

We have 10 compatible GPUs indexed for falcon-40b-instruct, including H100 NVL, RTX Pro 6000 Blackwell, MI300X, GH200, H200 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 falcon-40b-instruct?

Accepted Answer

The cheapest GPU to run falcon-40b-instruct in the cloud is the H100 NVL at $1.80/hr. Other affordable options include RTX Pro 6000 Blackwell ($1.89/hr) and MI300X ($1.99/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can falcon-40b-instruct run on consumer hardware?

Accepted Answer

Yes, falcon-40b-instruct 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 falcon-40b-instruct?

Accepted Answer

falcon-40b-instruct supports the following quantization levels: FP16 (full precision): ~89.40696716308594 GB, Q8 (8-bit): ~44.7 GB, Q6 (6-bit): ~33.5 GB, Q4 (4-bit): ~22.4 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.
