Frequently Asked Questions
- How much VRAM does Medqwen 0.5B need?
Medqwen 0.5B requires 1.3 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 494M × 16 bits ÷ 8 = 1 GB
KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 0.7 GB (at full 33K context)
VRAM usage by quantization
BF161.3 GBBF16 + full context1.7 GB- Can I run Medqwen 0.5B on a Mac?
Medqwen 0.5B requires at least 1.3 GB at BF16, 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 Medqwen 0.5B locally?
Yes — Medqwen 0.5B can run locally on consumer hardware. At BF16 quantization it needs 1.3 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Medqwen 0.5B?
At BF16, Medqwen 0.5B can reach ~2225 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~500 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 1.3 × 0.55 = ~2225 tok/s
