ftan-2.0

ftan-2.0 is a fine-tuned DistilBERT sequence classification model for detecting offensive text.

The model predicts one of two labels:

• clean — non-offensive text
• offensive — offensive text

Training

ftan-2.0 is the continuation of the akaruineko/bad-good-classifier-ru_en project.

The new version was trained on the akaruineko/offensively-neutral dataset, containing approximately 1.3 million text samples.

Training used a larger dataset than the previous model and included evaluation across multiple epochs to select the best-performing checkpoint.

The best checkpoint was selected based on evaluation performance rather than simply using the final training checkpoint.

Usage

from transformers import pipeline

classifier = pipeline(
    "text-classification",
    model="akaruineko/ftan-2.0"
)

result = classifier("you are stupid")
print(result)

Example:

[{'label': 'offensive', 'score': 0.965}]

Intended Use

ftan-2.0 can be used for:

• content moderation
• filtering offensive messages
• dataset preprocessing
• text classification experiments
• moderation pipelines
• research and experimentation with text classifiers

Limitations

This model should not be treated as a perfect moderation system.

Offensiveness can depend heavily on context, intent, quotation, sarcasm, reclaimed language, and the surrounding conversation. The model may therefore produce incorrect predictions for ambiguous or context-dependent text.

For example, a sentence discussing an offensive word may still receive a non-trivial offensive score even when the sentence itself is not an insult.

The model also operates on individual text inputs and does not have access to conversation history unless it is explicitly provided as input.

Example Predictions

Some example inference results:

"b****" # censored
→ offensive (0.988)

"you are stupid"
→ offensive (0.965)

"the word \"stupid\" is offensive"
→ offensive (0.695)

"beach"
→ clean (0.922)

These examples are illustrative and should not be interpreted as a formal benchmark.
