Question 1

How much VRAM does blip2-flan-t5-xxl need?

Accepted Answer

blip2-flan-t5-xxl (12.2B) requires approximately 27.335278701782226 GB of VRAM at full precision (FP16), 13.7 GB at 8-bit quantization (Q8), and 6.8 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 blip2-flan-t5-xxl?

Accepted Answer

We have 10 compatible GPUs indexed for blip2-flan-t5-xxl, including A40, L40S, L40, A100 40GB, 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 blip2-flan-t5-xxl?

Accepted Answer

The cheapest GPU to run blip2-flan-t5-xxl in the cloud is the A40 at $0.44/hr. Other affordable options include L40S ($0.60/hr) and L40 ($0.82/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can blip2-flan-t5-xxl run on consumer hardware?

Accepted Answer

Yes, blip2-flan-t5-xxl can run on consumer GPUs like the RTX A6000 (48 GB VRAM) at full precision (FP16).

Question 5

What quantization options are available for blip2-flan-t5-xxl?

Accepted Answer

blip2-flan-t5-xxl supports the following quantization levels: FP16 (full precision): ~27.335278701782226 GB, Q8 (8-bit): ~13.7 GB, Q6 (6-bit): ~10.3 GB, Q4 (4-bit): ~6.8 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.
