The workflow includes environment setup, prompt formatting, reward functions, and model evaluation to improve reasoning through group-sampled generations.", "body_md": "We build an end-to-end GRPO training workflow that teaches Gemma-3 to reason through GSM8K math problems. We prepare the environment, authenticate with Hugging Face, load Gemma-3, and wrap examples into a reasoning-plus-answer prompt format. We define reward functions for format adherence and numeric correctness, then attach LoRA adapters to keep training lightweight. We evaluate a baseline, run GRPO to improve the policy through group-sampled generations, and optionally export the merged model.\n\nThe post [Training Gemma-3 for Structured Mathematical Reasoning with Tunix GRPO, LoRA Adapters, and GSM8K Rewards](https://www.marktechpost.com/2026/07/05/training-gemma-3-for-structured-mathematical-reasoning-with-tunix-grpo-lora-adapters-and-gsm8k-rewards/) appeared first on [MarkTechPost](https://www.marktechpost.com).", "url": "https://wpnews.pro/news/training-gemma-3-for-structured-mathematical-reasoning-with-tunix-grpo-lora-and", "canonical_source": "https://www.marktechpost.com/2026/07/05/training-gemma-3-for-structured-mathematical-reasoning-with-tunix-grpo-lora-adapters-and-gsm8k-rewards/", "published_at": "2026-07-06 04:26:58+00:00", "updated_at": "2026-07-07 01:55:06.897269+00:00", "lang": "en", "topics": ["large-language-models", "machine-learning", "ai-research", "ai-tools"], "entities": ["Gemma-3", "Tunix", "LoRA", "GSM8K", "Hugging Face", "MarkTechPost"], "alternates": {"html": "https://wpnews.pro/news/training-gemma-3-for-structured-mathematical-reasoning-with-tunix-grpo-lora-and", "markdown": "https://wpnews.pro/news/training-gemma-3-for-structured-mathematical-reasoning-with-tunix-grpo-lora-and.md", "text": "https://wpnews.pro/news/training-gemma-3-for-structured-mathematical-reasoning-with-tunix-grpo-lora-and.txt", "jsonld": "https://wpnews.pro/news/training-gemma-3-for-structured-mathematical-reasoning-with-tunix-grpo-lora-and.jsonld"}}
