Tone Baseline v3

Model Summary

Tone Baseline v3 is a lightweight English text classification model designed to detect the communicative tone of short-form text.

The model predicts a single dominant tone, along with a confidence score and probability distribution across all supported tone categories. It is optimized for real-world production use, including writing assistants, browser extensions, and backend APIs.

Model Details

Model Description

• Developed by: Lokesh P
• Model type: Multi-class text classification (tone detection)
• Language(s): English
• License: Apache 2.0
• Framework: Hugging Face Transformers (PyTorch)
• Base Model: DistilBERT (distilbert-base-uncased)

The model is intended to be used as a pre-processing or analysis component in applications that need to understand how a piece of text is phrased (e.g., polite vs rude, questioning vs informational), rather than what the text is about.

---

Supported Tone Labels

The model predicts one of the following tone labels:

• supportive
• enthusiastic
• frustrated
• rude
• informational
• questioning
• formal
• assertive

Uses

Direct Use

This model can be used directly for:

• Tone detection in messages, emails, or chat inputs
• UX feedback on how a message may be perceived
• Pre-routing text into different rewrite or moderation pipelines
• Writing assistance tools

Example direct usage:

from transformers import pipeline

classifier = pipeline(
    "text-classification",
    model="LokeshDevCreates/tone-baseline-v3",
    top_k=None
)

text = "I strongly disagree with this decision."
result = classifier(text)
print(result)

---

Downstream Use

The model is commonly used as part of a larger system, for example:

• As an input signal for text rewriting systems
• As a decision layer before invoking a generative model
• As part of browser extensions or API services
• As a lightweight moderation or feedback component

---

Out-of-Scope Use

This model should NOT be used for:

• Psychological or mental health diagnosis
• Personality inference
• Detecting intent, deception, or truthfulness
• Legal, medical, or safety-critical decision making
• Surveillance or profiling of individuals

The model classifies text tone only, not user intent or emotional state.

---

Bias, Risks, and Limitations

Known Limitations

• English-only
• Performs best on short to medium-length text
• May misclassify sarcasm or highly contextual statements
• Sensitive to ambiguous phrasing
• Not designed for long documents or multi-paragraph inputs

Bias Considerations

The model reflects patterns present in its training data and may encode biases related to tone interpretation. Outputs should be treated as assistive signals, not absolute judgments.

---

Recommendations

• Use the model as one signal among many, not a final authority
• Avoid high-stakes automated decisions based solely on model output
• Perform task-specific evaluation before deployment in sensitive domains

How to Get Started

Using Transformers

from transformers import pipeline

classifier = pipeline(
    "text-classification",
    model="LokeshDevCreates/tone-baseline-v3",
    top_k=None
)

result = classifier("Can you explain this again?")
print(result)

Example Output

[
  {
    "label": "questioning",
    "score": 0.9992
  },
  {
    "label": "supportive",
    "score": 0.0002
  },
  {
    "label": "informational",
    "score": 0.0001
  }
]
