Question 1

How much VRAM does Fara1.5-27B need?

Accepted Answer

Fara1.5-27B (27.4B) requires approximately 61.14705330133438 GB of VRAM at full precision (FP16), 30.6 GB at 8-bit quantization (Q8), and 15.3 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 Fara1.5-27B?

Accepted Answer

We have 10 compatible GPUs indexed for Fara1.5-27B, 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 Fara1.5-27B?

Accepted Answer

The cheapest GPU to run Fara1.5-27B 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 Fara1.5-27B run on consumer hardware?

Accepted Answer

Yes, Fara1.5-27B 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 Fara1.5-27B?

Accepted Answer

Fara1.5-27B supports the following quantization levels: FP16 (full precision): ~61.14705330133438 GB, Q8 (8-bit): ~30.6 GB, Q6 (6-bit): ~22.9 GB, Q4 (4-bit): ~15.3 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.
