Frequently Asked Questions
- How much VRAM does Soren 1 Small need?
Soren 1 Small 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 on a Mac?
Soren 1 Small 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 locally?
Yes — Soren 1 Small 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?
At BF16, Soren 1 Small can reach ~701 tok/s on AMD Instinct MI300X. 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: AMD Instinct MI300X → 5300 ÷ 4.2 × 0.55 = ~701 tok/s
Estimated speed at BF16 (4.2 GB)
~701 tok/s~158 tok/s~524 tok/s~433 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Soren 1 Small?
At BF16, the download is about 3.76 GB.
- Which GPUs can run Soren 1 Small?
35 consumer GPUs can run Soren 1 Small at BF16 (4.2 GB). Top options include AMD Radeon RX 6700 XT, AMD Radeon RX 6800, AMD Radeon RX 6800 XT. 35 GPUs have plenty of headroom for comfortable inference.
- Which devices can run Soren 1 Small?
