speedbrain emotion classifier · English (ONNX)

CPU-ready ONNX export (dynamic int8 quantization) of SamLowe/roberta-base-go_emotions-onnx, used by the speedbrain injection-engine / Persona Forge to detect the user's emotion per chat turn and shift the character's Emotion Area (resonance). Label set: goemotions, folded into the canonical 7-emotion space (anger, disgust, fear, joy, neutral, sadness, surprise).

Usage (injection-engine)

python -m injection_pro_persona.fetch en

The engine loads model_quantized.onnx / model.onnx + tokenizer.json with onnxruntime (CPUExecutionProvider).
