PathFinder Flan-T5 Large Second Try — INT8 ONNX

INT8 ONNX encoder/decoder export stored with standard Optimum filenames for CPU deployment. The source directory is the PathFinderShip My Class/Second Try export.

Files

• encoder_model.onnx
• decoder_model.onnx
• decoder_with_past_model.onnx
• T5 tokenizer, model, and generation configuration files

The local source files used _int8 suffixes. Only the filenames were standardized for Optimum compatibility; the binary contents were not changed. The source-to-published mapping and SHA-256 values are recorded in ARTIFACT_SHA256.json.

Source-model evaluation

These scores belong to the source Second Try LoRA evaluation. They must not be interpreted as a separate ONNX parity benchmark. The complete comparison is included in evaluation/flan_retraining_results.json.

Usage

pip install "optimum[onnxruntime]" transformers

from optimum.onnxruntime import ORTModelForSeq2SeqLM
from transformers import AutoTokenizer

model_id = "Fatihaybasn/pathfinder-flan-t5-large-second-try-onnx-int8"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = ORTModelForSeq2SeqLM.from_pretrained(
    model_id,
    provider="CPUExecutionProvider",
)

Limitations

• The export is intended for ONNX Runtime CPU inference.
• Generation quality depends on the PathFinderShip prompt templates and decoding settings.
• A clean-download smoke test is required before deleting the local source files.
