Frequently Asked Questions
How much VRAM does Aragpt2 Base need?
Aragpt2 Base requires 0.1 GB of VRAM at Q4_K_M, or 0.3 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 148M × 4.8 bits ÷ 8 = 0.1 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 Aragpt2 Base?
For Aragpt2 Base, Q4_K_M (0.1 GB) offers the best balance of quality and VRAM usage. Q5_K_M (0.1 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 0.1 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Aragpt2 Base on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Aragpt2 Base. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 0.1 GB of usable unified memory (RAM minus macOS overhead).
Can I run Aragpt2 Base locally?
Yes — Aragpt2 Base can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Aragpt2 Base?
At Q4_K_M, Aragpt2 Base can reach ~48000 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~6552 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 ÷ 0.1 × 0.65 = ~52000 tok/s
Estimated speed at Q4_K_M (0.1 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Aragpt2 Base?
At Q4_K_M, the download is about 0.09 GB. The full-precision BF16 version is 0.30 GB. The smallest option (Q2_K) is 0.06 GB.
Which GPUs can run Aragpt2 Base?
52 consumer GPUs can run Aragpt2 Base at Q4_K_M. Top options include AMD Radeon RX 6700 XT, AMD Radeon RX 6800, AMD Radeon RX 6800 XT. 52 GPUs have plenty of headroom for comfortable inference.
Which devices can run Aragpt2 Base?
163 devices with unified memory can run Aragpt2 Base at Q4_K_M (0.1 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
