This repository contains the size- and memory-optimized ONNX exports of the FP32 model. For intended uses, class definitions, training data, benchmarks, and limitations, see the main model card.
Variants
| Variant | Path | Quantization |
|---|---|---|
| FP16 | onnx/fp16/model.onnx |
FP16 weights |
| INT8 | onnx/int8/model.onnx |
Post-training dynamic INT8 (MatMul/Gemm) |
| INT8 + INT4 embeddings | onnx/int8_int4_embeddings/model.onnx |
Dynamic INT8 plus 4-bit weight-only token embeddings |
The exact quantization parameters are recorded in onnx/quantization_manifest.json.
Benchmark
Quantization parity on the unified_v3 held-out test split (n = 1880; max_length 128, CPU):
| Variant | Accuracy | F1 (macro) | Δ F1 vs FP32 |
|---|---|---|---|
| FP32 reference (main repo) | 0.8984 | 0.8992 | - |
| FP16 | 0.8957 | 0.8966 | -0.0026 |
| INT8 | 0.8941 | 0.8962 | -0.0030 |
| INT8 + INT4 embeddings | 0.8931 | 0.8940 | -0.0052 |
Measured CPU latency (batch 64): ~18.98 ms/text for the INT8+INT4 build.
Full details in metrics/quant_bench.json.
Usage
from optimum.onnxruntime import ORTModelForSequenceClassification
from transformers import AutoTokenizer
model_id = "patronus-studio/panther-read-intent-classifier-edge"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = ORTModelForSequenceClassification.from_pretrained(model_id, subfolder="onnx/int8_int4_embeddings")
inputs = tokenizer("...", return_tensors="pt")
logits = model(**inputs).logits
Post-process the logits as described in the main model card (softmax over the logits, argmax).
