Frequently Asked Questions
- How much VRAM does RefinedToolCallV5 3B need?
RefinedToolCallV5 3B requires 2.2 GB of VRAM at Q4_K_M, or 6.5 GB at BF16. Full 131K context adds up to 4.8 GB (7.0 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 3.1B × 4.8 bits ÷ 8 = 1.9 GB
KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 5.1 GB (at full 131K context)
VRAM usage by quantization
Q4_K_M2.2 GBQ4_K_M + full context7.0 GB- What's the best quantization for RefinedToolCallV5 3B?
For RefinedToolCallV5 3B, Q4_K_M (2.2 GB) offers the best balance of quality and VRAM usage. Q5_K_M (2.6 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 1.7 GB.

- Can I run RefinedToolCallV5 3B on a Mac?
RefinedToolCallV5 3B requires at least 1.7 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 RefinedToolCallV5 3B locally?
Yes — RefinedToolCallV5 3B can run locally on consumer hardware. At Q4_K_M quantization it needs 2.2 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is RefinedToolCallV5 3B?
At Q4_K_M, RefinedToolCallV5 3B can reach ~1973 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~294 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 ÷ 2.2 × 0.65 = ~2332 tok/s
Estimated speed at Q4_K_M (2.2 GB)
~2332 tok/s~294 tok/s~2332 tok/s~1973 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of RefinedToolCallV5 3B?
At Q4_K_M, the download is about 1.85 GB. The full-precision BF16 version is 6.17 GB. The smallest option (Q2_K) is 1.31 GB.
