Question 1

How much VRAM does viscon-contextual-captioner need?

Accepted Answer

viscon-contextual-captioner (8.4B) requires approximately 18.781632006168365 GB of VRAM at full precision (FP16), 9.4 GB at 8-bit quantization (Q8), and 4.7 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 viscon-contextual-captioner?

Accepted Answer

We have 10 compatible GPUs indexed for viscon-contextual-captioner, including L4, A40, A100 40GB, A10G, RTX A6000 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 viscon-contextual-captioner?

Accepted Answer

The cheapest GPU to run viscon-contextual-captioner in the cloud is the L4 at $0.20/hr. Other affordable options include A40 ($0.44/hr) and A100 40GB ($0.93/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can viscon-contextual-captioner run on consumer hardware?

Accepted Answer

Yes, viscon-contextual-captioner can run on consumer GPUs like the RTX A6000 (48 GB VRAM) at full precision (FP16).

Question 5

What quantization options are available for viscon-contextual-captioner?

Accepted Answer

viscon-contextual-captioner supports the following quantization levels: FP16 (full precision): ~18.781632006168365 GB, Q8 (8-bit): ~9.4 GB, Q6 (6-bit): ~7 GB, Q4 (4-bit): ~4.7 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.
