⚑ 2-Line RAG Evaluation

bash
# Step 1: Generate QA pairs from your docs
ragscore generate docs/

# Step 2: Evaluate your RAG system
ragscore evaluate http://localhost:8000/query

That's it. Get accuracy scores and incorrect QA pairs instantly.

Code
============================================================
βœ… EXCELLENT: 85/100 correct (85.0%)
Average Score: 4.20/5.0
============================================================

❌ 15 Incorrect Pairs:

  1. Q: "What is RAG?"
     Score: 2/5 - Factually incorrect

  2. Q: "How does retrieval work?"
     Score: 3/5 - Incomplete answer

πŸš€ Quick Start

Install

Terminal
pip install ragscore              # Core (works with Ollama)
pip install "ragscore[openai]"    # + OpenAI support
pip install "ragscore[notebook]"  # + Jupyter/Colab support
pip install "ragscore[all]"       # + All providers

Already installed? Keep up to date β€” new versions add features like failure diagnosis and retrieved context capture:

Terminal
pip install --upgrade ragscore

Option 1: Python API (Notebook-Friendly)

Perfect for Jupyter, Colab, and rapid iteration. Get instant visualizations.

server.ts
from ragscore import quick_test

# 1. Audit your RAG in one line
result = quick_test(
    endpoint="http://localhost:8000/query",  # Your RAG API
    docs="docs/",                            # Your documents
    n=10,                                    # Number of test questions
)

# 1b. Tailored QA β€” target specific audiences
result = quick_test(
    endpoint="http://localhost:8000/query",
    docs="docs/",
    audience="developers",                   # Who asks the questions?
    purpose="api-integration",               # What's the document for?
)

# 2. See the report
result.plot()

# 3. Inspect failures
bad_rows = result.df[result.df['score'] < 3]
display(bad_rows[['question', 'rag_answer', 'reason']])

Rich Object API:

  • result.accuracy - Accuracy score
  • result.df - Pandas DataFrame of all results
  • result.plot() - 3-panel visualization (4-panel with detailed=True)
  • result.corrections - List of items to fix

Option 2: CLI (Production)

Generate QA Pairs

server.ts
# Set API key (or use local Ollama - no key needed!)
export OPENAI_API_KEY="sk-..."

# Generate from any document
ragscore generate paper.pdf
ragscore generate docs/*.pdf --concurrency 10

# Tailored QA generation β€” target specific audiences
ragscore generate docs/ --audience developers --purpose faq
ragscore generate docs/ --audience customers --purpose "pre-sales"
ragscore generate docs/ --audience "compliance auditors" --purpose "security audit"

Evaluate Your RAG

bash
# Point to your RAG endpoint
ragscore evaluate http://localhost:8000/query

# Custom options
ragscore evaluate http://api/ask --model gpt-4o --output results.json

πŸ”¬ Detailed Multi-Metric Evaluation

Go beyond a single score. Add detailed=True to get 5 diagnostic dimensions per answer β€” in the same single LLM call.

python
result = quick_test(
    endpoint=my_rag,
    docs="docs/",
    n=10,
    detailed=True,  # ⭐ Enable multi-metric evaluation
)

# Inspect per-question metrics
display(result.df[[
    "question", "score", "correctness", "completeness",
    "relevance", "conciseness", "faithfulness"
]])

# Radar chart + 4-panel visualization
result.plot()
Code
==================================================
βœ… PASSED: 9/10 correct (90%)
Average Score: 4.3/5.0
Threshold: 70%
──────────────────────────────────────────────────
  Correctness: 4.5/5.0
  Completeness: 4.2/5.0
  Relevance: 4.8/5.0
  Conciseness: 4.1/5.0
  Faithfulness: 4.6/5.0
==================================================
MetricWhat it measuresScale
CorrectnessSemantic match to golden answer5 = fully correct
CompletenessCovers all key points5 = fully covered
RelevanceAddresses the question asked5 = perfectly on-topic
ConcisenessFocused, no filler5 = concise and precise
FaithfulnessNo fabricated claims5 = fully faithful

CLI:

bash
ragscore evaluate http://localhost:8000/query --detailed

πŸ” Failure Diagnosis (--diagnose)

When answers fail, --diagnose tells you why β€” retriever miss, generator hallucination, incomplete answer, or wrong interpretation:

bash
ragscore evaluate http://localhost:8000/query --diagnose
Code
πŸ” Failure Diagnosis:
  Retriever Miss: 3 (42.9%)
  Generator Hallucination: 2 (28.6%)
  Incomplete Answer: 1 (14.3%)
  Wrong Interpretation: 1 (14.3%)

Uses the support_span already generated with each QA pair to give the judge grounding context. Combine with --detailed for full diagnostics:

bash
ragscore evaluate http://localhost:8000/query --diagnose --detailed -o results.json
CategoryMeaning
Retriever MissRAG didn't retrieve the chunk containing the evidence
Generator HallucinationRetrieved correctly but fabricated information
Incomplete AnswerRetrieved correctly but answer is partial
Wrong InterpretationRetrieved correctly but misunderstood the content

πŸ““ Full demo notebook β€” build a mini RAG and test it with detailed metrics.

🎯 Audience & Purpose demo β€” generate tailored QA for developers, customers, auditors, and more.

Ollama Model Recommendations

RAGScore generates complex structured QA pairs (question + answer + rationale + support span) in JSON format. This requires models with strong instruction-following and JSON output capabilities.

ModelSizeMin RAMQA QualityRecommended
llama3.1:70b40GB48GB VRAMExcellentGPU server (A100, L40)
qwen2.5:32b18GB24GB VRAMExcellentGPU server (A10, L20)
llama3.1:8b4.7GB8GB VRAMGoodBest local choice
qwen2.5:7b4.4GB8GB VRAMGoodGood local alternative
mistral:7b4.1GB8GB VRAMGoodGood local alternative
llama3.2:3b2.0GB4GB RAMFairCPU-only / testing
qwen2.5:1.5b1.0GB2GB RAMPoorNot recommended

Minimum recommended: 8B+ models. Smaller models (1.5B–3B) produce lower quality support spans and may timeout on longer chunks.

Ollama Performance Guide

bash
# Recommended: 8B model with concurrency 2 for local machines
ollama pull llama3.1:8b
ragscore generate docs/ --provider ollama --model llama3.1:8b

# GPU server (A10/L20): larger model with higher concurrency
ollama pull qwen2.5:32b
ragscore generate docs/ --provider ollama --model qwen2.5:32b --concurrency 5

Expected performance (28 chunks, 5 QA pairs per chunk):

HardwareModelTimeConcurrency
MacBook (CPU)llama3.2:3b~45 min2
MacBook (CPU)llama3.1:8b~25 min2
A10 (24GB)llama3.1:8b~3–5 min5
L20/L40 (48GB)qwen2.5:32b~3–5 min5
OpenAI APIgpt-4o-mini~2 min10

RAGScore auto-reduces concurrency to 2 for local Ollama to avoid GPU/CPU contention.
