Question 1

How much VRAM does Solar-Open-100B need?

Accepted Answer

Solar-Open-100B (102.7B) requires approximately 227.75713806152342 GB of VRAM at full precision (FP16), 113.9 GB at 8-bit quantization (Q8), and 56.9 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 Solar-Open-100B?

Accepted Answer

We have 2 compatible GPUs indexed for Solar-Open-100B, including MI325X, MI350X. 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 Solar-Open-100B?

Accepted Answer

Question 4

Can Solar-Open-100B run on consumer hardware?

Accepted Answer

Solar-Open-100B requires approximately 227.75713806152342 GB of VRAM at FP16, and even with 4-bit quantization (Q4) it needs about 56.9 GB. This exceeds the 24 GB available on the highest-end consumer GPU (RTX 4090), so Solar-Open-100B requires datacenter or cloud GPUs.

Question 5

What quantization options are available for Solar-Open-100B?

Accepted Answer

Solar-Open-100B supports the following quantization levels: FP16 (full precision): ~227.75713806152342 GB, Q8 (8-bit): ~113.9 GB, Q6 (6-bit): ~85.4 GB, Q4 (4-bit): ~56.9 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. As a Mixture of Experts (MoE) model with 128 experts (8 active), Solar-Open-100B has a larger total weight size but only activates a subset of parameters per token, which can affect effective memory usage during inference.
