dystrio/Llama-3.1-8B-Instruct-sculpt-default

10% smaller, quality preserved (1.0641x PPL), drop-in replacement. No custom kernels. No runtime changes.

Dystrio Sculpt structurally compresses transformer models, producing dense models that load with standard transformers — no custom code, no new ops, no deployment friction.

This is the Default tier of Llama 3.1 8B Instruct.

Quick Start

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("dystrio/Llama-3.1-8B-Instruct-sculpt-default", torch_dtype="bfloat16", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("dystrio/Llama-3.1-8B-Instruct-sculpt-default")

inputs = tokenizer("The future of AI inference is", return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=100)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

What is Dystrio Sculpt?

Dystrio Sculpt compiles transformer models into smaller, faster variants. Output models:

• Are dense (not sparse) — standard architecture, fewer parameters
• Load with standard HuggingFace Transformers — no custom code needed
• Require no custom kernels and no runtime changes
• Work as a one-step compile before deployment
• Stack with quantization (AWQ, GPTQ, GGUF) for compound savings

Compatibility

• ✅ HuggingFace Transformers
• ✅ vLLM
• ✅ TGI (Text Generation Inference)
• ✅ llama.cpp / GGUF conversion
• ✅ AWQ / GPTQ quantization
• ✅ Any framework that loads standard safetensors

Benchmark Environment

• GPU: NVIDIA A100-SXM4-80GB
• dtype: bf16
• Torch: 2.10.0+cu128
• Transformers: 5.3.0
• Deterministic: True
• Single-GPU, standard HuggingFace Transformers, no custom kernels.

Metric Definitions

• PPL ratio: WikiText-103 perplexity relative to baseline. <1.0 = quality improved.
• Prefill TPS: Tokens per second during prompt encoding (higher = faster).
• TTFT p95: Time to first token at 95th percentile (lower = faster).
• Decode TPS: Tokens per second during generation (higher = faster).
• Weights (GB): Model parameter memory (deterministic, runtime-independent).
