Frequently Asked Questions
- How much VRAM does Natural Sql 7B need?
Natural Sql 7B requires 5.5 GB of VRAM at Q4_K_M, or 15.1 GB at FP16. Full 4K context adds up to 1.0 GB (6.5 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 6.9B × 4.8 bits ÷ 8 = 4.1 GB
KV Cache + Overhead ≈ 1.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 2.4 GB (at full 4K context)
VRAM usage by quantization
Q4_K_M5.5 GBQ4_K_M + full context6.5 GB- What's the best quantization for Natural Sql 7B?
For Natural Sql 7B, Q4_K_M (5.5 GB) offers the best balance of quality and VRAM usage. Q5_K_S (6.1 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 3.2 GB.

- Can I run Natural Sql 7B on a Mac?
Natural Sql 7B requires at least 3.2 GB at IQ2_XXS, 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 Natural Sql 7B locally?
Yes — Natural Sql 7B can run locally on consumer hardware. At Q4_K_M quantization it needs 5.5 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Natural Sql 7B?
At Q4_K_M, Natural Sql 7B can reach ~881 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~120 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 ÷ 5.5 × 0.65 = ~954 tok/s
Estimated speed at Q4_K_M (5.5 GB)
~954 tok/s~120 tok/s~954 tok/s~881 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Natural Sql 7B?
At Q4_K_M, the download is about 4.15 GB. The full-precision FP16 version is 13.82 GB. The smallest option (IQ2_XXS) is 1.90 GB.
- Which GPUs can run Natural Sql 7B?
