Frequently Asked Questions
How much VRAM does Hy3 REAP 200B 21B need?
Hy3 REAP 200B 21B requires 120.4 GB of VRAM at Q4_K_M, or 399.8 GB at BF16. Full 262K context adds up to 42.6 GB (163 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 199.6B × 4.8 bits ÷ 8 = 119.8 GB
KV Cache + Overhead ≈ 0.6 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 ≈ 43.2 GB (at full 262K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run Hy3 REAP 200B 21B?
No — Hy3 REAP 200B 21B requires at least 68 GB at IQ2_M, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
What's the best quantization for Hy3 REAP 200B 21B?
For Hy3 REAP 200B 21B, Q4_K_M (120.4 GB) offers the best balance of quality and VRAM usage. Q5_K_M (142.8 GB) provides better quality if you have the VRAM. The smallest option is IQ2_M at 68 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Hy3 REAP 200B 21B on a Mac?
Yes — Mac Studio (M3 Ultra, 96GB) and 20 other Macs can run Hy3 REAP 200B 21B, the smallest at Q2_K. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 120.4 GB of usable unified memory (RAM minus macOS overhead), from Mac Pro M2 Ultra (128 GB).
Can I run Hy3 REAP 200B 21B locally?
Yes — Hy3 REAP 200B 21B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Hy3 REAP 200B 21B?
At Q4_K_M, Hy3 REAP 200B 21B can reach ~55 tok/s on AMD Instinct MI350X. 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 → 11.1 GB active ÷ (8000 × 0.65) = 2.13 ms, plus 80 layers × 0.055 ms = 4.40 ms, so 1000 ÷ 6.53 ms = ~153 tok/s
Estimated speed at Q4_K_M (120.4 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Hy3 REAP 200B 21B?
At Q4_K_M, the download is about 119.75 GB. The full-precision BF16 version is 399.17 GB. The smallest option (IQ2_M) is 67.36 GB.
Which GPUs can run Hy3 REAP 200B 21B?
No single consumer GPU has enough VRAM to run Hy3 REAP 200B 21B at Q4_K_M (120.4 GB). Multi-GPU or professional hardware is required.
Which devices can run Hy3 REAP 200B 21B?
15 devices with unified memory can run Hy3 REAP 200B 21B at Q4_K_M (120.4 GB), including Mac Pro M2 Ultra (128 GB), Mac Pro M2 Ultra (192 GB), Mac Studio (M3 Ultra, 256GB), Mac Studio (M3 Ultra, 512GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
