Frequently Asked Questions
- How much VRAM does Qwen3 Coder REAP 25B A3B need?
Qwen3 Coder REAP 25B A3B requires 15.3 GB of VRAM at Q4_K_M, or 50.1 GB at BF16. Full 262K context adds up to 12.8 GB (28.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 24.9B × 4.8 bits ÷ 8 = 14.9 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 13.2 GB (at full 262K context)
VRAM usage by quantization
Q4_K_M15.3 GBQ4_K_M + full context28.1 GB- Can NVIDIA GeForce RTX 4090 run Qwen3 Coder REAP 25B A3B?
Yes, at Q6_K (20.9 GB) or lower. Higher quantizations like Q8_0 (25.3 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for Qwen3 Coder REAP 25B A3B?
For Qwen3 Coder REAP 25B A3B, Q4_K_M (15.3 GB) offers the best balance of quality and VRAM usage. Q5_K_M (18.1 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 11.0 GB.

- Can I run Qwen3 Coder REAP 25B A3B on a Mac?
Qwen3 Coder REAP 25B A3B requires at least 11.0 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Qwen3 Coder REAP 25B A3B locally?
Yes — Qwen3 Coder REAP 25B A3B can run locally on consumer hardware. At Q4_K_M quantization it needs 15.3 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Qwen3 Coder REAP 25B A3B?
At Q4_K_M, Qwen3 Coder REAP 25B A3B can reach ~313 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~43 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 ÷ 15.3 × 0.65 = ~339 tok/s
Estimated speed at Q4_K_M (15.3 GB)
~339 tok/s~43 tok/s~339 tok/s~313 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
