hikmaai-codebert-base-code-detection

A binary classifier that detects whether the input contains source code, fine-tuned from microsoft/codebert-base by HikmaAI.

Model Description

Task: Binary classification (safe=0, threat=1, where "threat" = code detected)
Base model: microsoft/codebert-base
Export formats: ONNX FP32 + INT8 dynamic quantization

Performance

See model_card.json for detailed metrics.

Optimized threshold: 0.9950 (val recall: 0.9984)

Usage (ONNX)

python

from optimum.onnxruntime import ORTModelForSequenceClassification
from transformers import AutoTokenizer

model = ORTModelForSequenceClassification.from_pretrained(
    "HikmaAI/hikmaai-codebert-base-code-detection",
    subfolder="onnx/int8",
)
tokenizer = AutoTokenizer.from_pretrained(
    "HikmaAI/hikmaai-codebert-base-code-detection",
    subfolder="tokenizer",
)

inputs = tokenizer("def hello():\n    print('hi')", return_tensors="pt")
outputs = model(**inputs)
# outputs.logits -> [safe_score, threat_score]
