Frequently Asked Questions
How much VRAM does Ko PlatYi 6B need?
Ko PlatYi 6B requires 4.0 GB of VRAM at Q4_K_M, or 12.4 GB at FP16.
VRAM = Weights + KV Cache + Overhead
Weights = 6B × 4.8 bits ÷ 8 = 3.6 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.
VRAM usage by quantization
What's the best quantization for Ko PlatYi 6B?
For Ko PlatYi 6B, Q4_K_M (4.0 GB) offers the best balance of quality and VRAM usage. Q5_K_M (4.7 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 3.0 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Ko PlatYi 6B on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Ko PlatYi 6B. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 4.0 GB of usable unified memory (RAM minus macOS overhead).
Can I run Ko PlatYi 6B locally?
Yes — Ko PlatYi 6B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Ko PlatYi 6B?
At Q4_K_M, Ko PlatYi 6B can reach ~1191 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~163 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 ÷ 4.03 × 0.65 = ~1290 tok/s
Estimated speed at Q4_K_M (4.0 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Ko PlatYi 6B?
At Q4_K_M, the download is about 3.60 GB. The full-precision FP16 version is 12.00 GB. The smallest option (Q2_K) is 2.55 GB.
Which GPUs can run Ko PlatYi 6B?
52 consumer GPUs can run Ko PlatYi 6B 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 Ko PlatYi 6B?
163 devices with unified memory can run Ko PlatYi 6B at Q4_K_M (4.0 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.
