Model Description

Training Data

datasets: Ramikan-BR/data-oss_instruct-decontaminated_python.jsonl

Training Procedure

The model was refined using Unsloath. The dataset ise-uiuc/Magicoder-OSS-Instruct-75K was adjusted, leaving only data on python and divided into 10 parts, each refinement occurred for 2 epochs, using adafactor optimizer or adamw_8bit (adafactor seems to deliver less loss).
