# RAG-FiT vs ARES

*GraphCanon updated Aug 24, 2026*

## Verdict

Pick RAG-FiT if rAG-FiT is a Python framework that enables developers to fine-tune large language models specifically for Retriever-Augmented Generation (RAG) tasks, with strengths in evaluation and information retrieval; pick ARES if automated evaluation for RAG systems with API integrations like OpenAI.

[RAG-FiT](https://intellabs.github.io/RAG-FiT/) reports 769 GitHub stars, 61 forks, and 1 open issues, last pushed Jun 8, 2026. [ARES](https://ares-ai.vercel.app/) has 731 stars, 67 forks, and 21 open issues, last pushed Mar 28, 2025. Figures are from public GitHub metadata via [RAG-FiT's repository](https://github.com/IntelLabs/RAG-FiT) and [ARES's repository](https://github.com/stanford-futuredata/ARES).

## Choose when

### Choose RAG-FiT if…

- Requirements: This framework requires proficiency in Python and an understanding of RAG tasks to be effectively utilized..
- Tags unique to RAG-FiT: evaluation, fine-tuning, information-retrieval, llm.
- Also covers Model Training.
- When seeking to improve performance of LLMs in NLP tasks requiring RAG capabilities, like question-answering or semantic search

### Choose ARES if…

- Tags unique to ARES: automated scoring, human validation sets, python, rag evaluation.
- Evaluating Retrieval-Augmented Generation (RAG) systems that require automatic scoring using human-annotated data and few-shot examples.

## When NOT to use RAG-FiT

- If project needs are more aligned with traditional fine-tuning methods that do not specifically enhance RAG capabilities, another tool might be more suitable
- In scenarios where the development team lacks proficiency in Python, as RAG-FiT is Python-based and may have a steeper learning curve for non-Python developers

## When NOT to use ARES

- Avoid if limited to non-GPU machines with less than ~100GB available disk space, as it encounters CUDA out-of-memory errors without compatible GPU setups.
