Frequently Asked Questions
How much VRAM does MiniLLM Gpt2 340M need?
MiniLLM Gpt2 340M requires 0.2 GB of VRAM at Q4_K_M, or 0.8 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 340M × 4.8 bits ÷ 8 = 0.2 GB
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
VRAM usage by quantization
What's the best quantization for MiniLLM Gpt2 340M?
For MiniLLM Gpt2 340M, Q4_K_M (0.2 GB) offers the best balance of quality and VRAM usage. Q5_K_M (0.3 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 0.2 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run MiniLLM Gpt2 340M on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run MiniLLM Gpt2 340M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 0.2 GB of usable unified memory (RAM minus macOS overhead).
Can I run MiniLLM Gpt2 340M locally?
Yes — MiniLLM Gpt2 340M can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is MiniLLM Gpt2 340M?
At Q4_K_M, MiniLLM Gpt2 340M can reach ~21818 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~2978 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 ÷ 0.22 × 0.65 = ~23636 tok/s
Estimated speed at Q4_K_M (0.2 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of MiniLLM Gpt2 340M?
At Q4_K_M, the download is about 0.20 GB. The full-precision BF16 version is 0.68 GB. The smallest option (Q2_K) is 0.14 GB.
