# flan-t5-base-pt2 — Essay Trait Scorer

This model is a fine-tuned version of `google/flan-t5-base` designed for trait-based essay scoring. It was trained on Sets 7 & 8 of the ASAP AES dataset, extended with floating-point scoring and GPT validation. 

Each input includes:
- a trait (e.g., Ideas, Organization),
- the relevant rubric definition,
- and the student's essay.

The model outputs a trait-specific score between **0.0 and 3.0**, which can be scaled to a final grade out of 100.

🧠 Scoring is optionally cross-validated with OpenAI’s GPT for more reliable results.

## Usage

```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("srutiii/flan-t5-base-pt2")
model = AutoModelForSeq2SeqLM.from_pretrained("srutiii/flan-t5-base-pt2")
