Frequently Asked Questions

How much VRAM does Stories15M MOE need?

Stories15M MOE requires 0.3 GB of VRAM at Q4_K_M, or 0.4 GB at BF16.

VRAM = Weights + KV Cache + Overhead

Weights = 36M × 4.8 bits ÷ 8 = 0 GB

KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

Can I run Stories15M MOE on a Mac?

Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Stories15M MOE. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 0.3 GB of usable unified memory (RAM minus macOS overhead).

Can I run Stories15M MOE locally?

Yes — Stories15M MOE can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Stories15M MOE?

At Q4_K_M, Stories15M MOE can reach ~797 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~1360 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)

Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.

Example: NVIDIA B200 → 0.3 GB active ÷ (8000 × 0.65) = 0.0511 ms, plus 6 layers × 0.055 ms = 0.3300 ms, so 1000 ÷ 0.3811 ms = ~2624 tok/s

Estimated speed at Q4_K_M (0.3 GB)

~1360 tok/s
~2624 tok/s
~2419 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
