Quick Start

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("continuum-ai/qwen3.5-4b-code-forged",
    torch_dtype="auto", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("continuum-ai/qwen3.5-4b-code-forged")

inputs = tokenizer("def merge_sort(arr):", return_tensors="pt").to(model.device)
output = model.generate(**inputs, max_new_tokens=200)
print(tokenizer.decode(output[0], skip_special_tokens=True))

Methodology

Produced via GGUF quantization. Full methodology, ablations, and per-stage rationale are in the methodology paper and the companion `MODEL_METHODOLOGY.md` in this repository. The pipeline ran as train → quant → eval over 3 cycles on NVIDIA GeForce RTX 5090.
