dystrio/Qwen2.5-3B-Instruct-sculpt-throughput

19% smaller, +16% faster prefill, drop-in replacement. No custom kernels. No runtime changes.

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

This is the Throughput tier of Qwen2.5 3B Instruct.

Quick Start

python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("dystrio/Qwen2.5-3B-Instruct-sculpt-throughput", torch_dtype="bfloat16", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("dystrio/Qwen2.5-3B-Instruct-sculpt-throughput")

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:

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

Compatibility

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

Benchmark Environment

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

Metric Definitions

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