The problem

Adapting a general language model to coding tasks needs a reproducible path from instruction examples to training artifacts. Parameter-efficient fine-tuning makes that workflow more approachable.

The approach

  1. Convert CodeAlpaca-20k instruction, input, and response examples into consistent JSONL training records.
  2. Load Gemma in 4-bit precision and configure PEFT LoRA adapters on query and value projections.
  3. Use gradient accumulation during training and save the model and tokenizer artifacts for subsequent inference experiments.

The result

A reproducible workflow for parameter-efficient Gemma fine-tuning on code instruction data.

The engineering decision

Parameter-efficient fine-tuning reduces training memory requirements while keeping the base model frozen. Training data quality and evaluation remain essential to useful coding assistance.
