Frequently Asked Questions
- How much VRAM does Bielik 4.5B V3.0 Instruct need?
Bielik 4.5B V3.0 Instruct requires 10.5 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 4.8B × 16 bits ÷ 8 = 9.5 GB
KV Cache + Overhead ≈ 1 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
BF1610.5 GB- Can I run Bielik 4.5B V3.0 Instruct on a Mac?
Bielik 4.5B V3.0 Instruct requires at least 10.5 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 Bielik 4.5B V3.0 Instruct locally?
Yes — Bielik 4.5B V3.0 Instruct can run locally on consumer hardware. At BF16 quantization it needs 10.5 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Bielik 4.5B V3.0 Instruct?
At BF16, Bielik 4.5B V3.0 Instruct can reach ~278 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~63 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 ÷ 10.5 × 0.55 = ~278 tok/s
Estimated speed at BF16 (10.5 GB)
~278 tok/s~63 tok/s~208 tok/s~172 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
