Question 1

How much VRAM does Step-3.7-Flash need?

Accepted Answer

Step-3.7-Flash (201.4B) requires approximately 450.08655524253845 GB of VRAM at full precision (FP16), 225 GB at 8-bit quantization (Q8), and 112.5 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 Step-3.7-Flash?

Accepted Answer

We currently have no compatible GPUs indexed for Step-3.7-Flash. This may be because the model's VRAM requirements exceed available GPUs in our database, or VRAM data hasn't been computed yet.

Question 3

What is the cheapest GPU to run Step-3.7-Flash?

Accepted Answer

We don't currently have cloud pricing data for GPUs compatible with Step-3.7-Flash. Cloud pricing data is updated regularly — check back soon.

Question 4

Can Step-3.7-Flash run on consumer hardware?

Accepted Answer

Step-3.7-Flash requires approximately 450.08655524253845 GB of VRAM at FP16, and even with 4-bit quantization (Q4) it needs about 112.5 GB. This exceeds the 24 GB available on the highest-end consumer GPU (RTX 4090), so Step-3.7-Flash requires datacenter or cloud GPUs.

Question 5

What quantization options are available for Step-3.7-Flash?

Accepted Answer

Step-3.7-Flash supports the following quantization levels: FP16 (full precision): ~450.08655524253845 GB, Q8 (8-bit): ~225 GB, Q6 (6-bit): ~168.8 GB, Q4 (4-bit): ~112.5 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.
