ποΈ Mathematical Quantization Architecture
ArkCompact quantizes weights into ternary states using Base-3 Packing (5 trits per byte):
This eliminates 16-bit floating-point multiplications, replacing them with integer accumulations and fused Wave32 bitwise masks:
- Zero-Copy Memory-Mapped Loading (
mmap): Model initializes in $< 450\text{ ms}$. - Multi-Head Latent Attention (MLA): KV-Cache footprint reduced by $-85.9%$.
- Chunked Prefill: Eliminates Head-of-Line blocking in continuous batching.
π Quickstart & Inference
1. Run natively with ark-engine (Rust Server)
# Clone and build ArkheionNet
git clone https://github.com/Arkheion/ArkheionNet.git
cd ArkheionNet
cargo build --release -p ark-engine
# Start sovereign server on port 11500
./target/release/ark-engine server --port 11500 --model output/granite-3.2-2b.ark
2. Query via OpenAI-Compatible REST API
curl http://localhost:11500/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"model": "Granite-3.2-2B-ArkCompact-1.58bit",
"messages": [
{"role": "user", "content": "Explain quantum decoherence in simple terms."}
],
"temperature": 0.2,
"max_tokens": 512
}'
3. Use via ark-sdk (Rust)
use ark_sdk::ArkClient;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let client = ArkClient::new("http://localhost:11500");
let mut stream = client.generate_stream("Granite-3.2-2B-ArkCompact-1.58bit", "Hello Arkheion!").await?;
while let Some(chunk) = stream.next().await {
print!("{}", chunk?.response);
}
Ok(())
}
