ModernBERT-GoEmotions

ModernBERT-GoEmotions

Model Summary

ModernBERT-GoEmotions is a fine-tuned Transformer-based model for multi-label emotion classification.
Given a short text input, the model predicts one or more emotions from a predefined set of 27 emotions + neutral, as defined in the GoEmotions dataset.

The model is designed for applications requiring fine-grained emotional understanding, such as affective chat systems, moderation pipelines, and sentiment-aware conversational agents.

Uses

Direct Use

The model can be used directly to:

• Detect multiple emotions in short English texts
• Analyze emotional tone in social media posts or chats
• Power emotion-aware chat or moderation systems

Downstream Use

The model may be integrated into:

• Conversational AI pipelines
• Mental health or well-being analytics (non-diagnostic)
• Emotion-aware recommendation systems
• Research on affective computing

Out-of-Scope Use

The model is not intended for:

• Medical or psychological diagnosis
• Legal or forensic decision-making
• High-stakes autonomous systems
• Real-time moderation without human oversight

Bias, Risks, and Limitations

• The training data is derived from Reddit, which may contain demographic, cultural, and topical biases
• Emotion labels may be subjective and context-dependent
• The model does not explicitly model emotion intensity or temporal dynamics
• Predictions should be interpreted as probabilistic signals, not ground truth

Recommendations

• Use human-in-the-loop validation for sensitive applications
• Calibrate thresholds per emotion for production use
• Avoid over-reliance on single-label interpretations

How to Get Started with the Model

from transformers import pipeline

classifier = pipeline(
    "text-classification",
    model="your-username/ModernBERT-GoEmotions",
    return_all_scores=True
)

classifier("I feel anxious but also hopeful about the future.")
