Frequently Asked Questions
How much VRAM does Distil Lfm25 Shellper need?
Distil Lfm25 Shellper requires 0.6 GB of VRAM at Q4_K_M, or 1.1 GB at BF16. Full 128K context adds up to 1.8 GB (2.4 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 354M × 4.8 bits ÷ 8 = 0.2 GB
KV Cache + Overhead ≈ 0.4 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.
KV Cache + Overhead ≈ 2.2 GB (at full 128K context)
VRAM usage by quantization
What's the best quantization for Distil Lfm25 Shellper?
For Distil Lfm25 Shellper, Q4_K_M (0.6 GB) offers the best balance of quality and VRAM usage. Q5_K_M (0.6 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 0.5 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Distil Lfm25 Shellper on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Distil Lfm25 Shellper. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 0.6 GB of usable unified memory (RAM minus macOS overhead).
Can I run Distil Lfm25 Shellper locally?
Yes — Distil Lfm25 Shellper can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Distil Lfm25 Shellper?
At Q4_K_M, Distil Lfm25 Shellper can reach ~8276 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~1130 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 0.58 × 0.65 = ~8966 tok/s
Estimated speed at Q4_K_M (0.6 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Distil Lfm25 Shellper?
At Q4_K_M, the download is about 0.21 GB. The full-precision BF16 version is 0.71 GB. The smallest option (Q2_K) is 0.15 GB.
