Frequently Asked Questions
- How much VRAM does Soren 1 Small Heretic need?
Soren 1 Small Heretic requires 4.2 GB of VRAM at BF16. Full 1049K context adds up to 51.4 GB (55.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 1.9B × 16 bits ÷ 8 = 3.8 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 51.8 GB (at full 1049K context)
VRAM usage by quantization
BF164.2 GBBF16 + full context55.6 GB- Can I run Soren 1 Small Heretic on a Mac?
Soren 1 Small Heretic requires at least 4.2 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 Soren 1 Small Heretic locally?
Yes — Soren 1 Small Heretic can run locally on consumer hardware. At BF16 quantization it needs 4.2 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Soren 1 Small Heretic?
At BF16, Soren 1 Small Heretic can reach ~1058 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~158 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 ÷ 4.2 × 0.65 = ~1250 tok/s
Estimated speed at BF16 (4.2 GB)
~1250 tok/s~158 tok/s~1250 tok/s~1058 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
