Dapinsky/PIT-4B-FT-202212-math-reasoning-dpo

This repo contains a full merged model produced from Dapinsky/PIT-4B-FT-202212-math-reasoning-sft and a PEFT LoRA adapter. It is intended to be loadable with the same Transformers API used for the base Diamegs PIT model:

from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("Dapinsky/PIT-4B-FT-202212-math-reasoning-dpo", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("Dapinsky/PIT-4B-FT-202212-math-reasoning-dpo", trust_remote_code=True)

Training Summary

• Base model: Dapinsky/PIT-4B-FT-202212-math-reasoning-sft
• Fine-tuning method: LoRA post-training, merged into the base weights for upload.
• Tokenizer files copied from: base model
