Benchmarks

We evaluate haiku.rag on several datasets to measure both retrieval quality and question-answering accuracy.

Running Evaluations

You can run evaluations with the evaluations CLI:

evaluations run repliqa
evaluations run wix

The evaluation flow is orchestrated with pydantic-evals, which we leverage for dataset management, scoring, and report generation.

Pre-built Databases

Building evaluation databases from scratch can take a long time, especially for large datasets like OpenRAG Bench. Pre-built databases are available on HuggingFace:

# Download a specific dataset
evaluations download repliqa

# Download all datasets
evaluations download all

# Force re-download (overwrite existing)
evaluations download repliqa --force

Available datasets:

Dataset	Size
repliqa	~30MB
hotpotqa	~331MB
wix	~511MB
open_rag_bench	~14GB

After downloading, run benchmarks with --skip-db to use the pre-built database:

evaluations run repliqa --skip-db

Configuration

The benchmark script accepts several options:

evaluations run repliqa --config /path/to/haiku.rag.yaml --db /path/to/custom.lancedb

Options:

• --config PATH - Specify a custom haiku.rag.yaml configuration file
• --db PATH - Override the database path (default: platform-specific user data directory)
• --skip-db - Skip updating the evaluation database
• --skip-retrieval - Skip retrieval benchmark
• --skip-qa - Skip QA benchmark
• --limit N - Limit number of test cases
• --name NAME - Override the evaluation name

If no config file is specified, the script searches standard locations: ./haiku.rag.yaml, user config directory, then falls back to defaults.

Methodology

Retrieval Metrics

Mean Reciprocal Rank (MRR) - Used when each query has exactly one relevant document.

• For each query, find the rank (position) of the first relevant document in top-K results
• Reciprocal rank = 1/rank (e.g., rank 3 → 1/3 ≈ 0.333)
• If not found in top-K, score is 0
• MRR is the mean across all queries
• Range: 0 (never found) to 1 (always at rank 1)

Mean Average Precision (MAP) - Used when queries have multiple relevant documents.

• For each relevant document at position k, calculate precision@k = (relevant docs in top k) / k
• Average Precision (AP) = mean of these precision values / total relevant documents
• MAP is the mean of AP scores across all queries
• Range: 0 to 1; rewards ranking relevant documents higher

QA Accuracy

For question-answering evaluation, pydantic-evals coordinates an LLM judge (Ollama qwen3) to determine whether answers are correct. Accuracy is the fraction of correctly answered questions.

RepliQA

RepliQA contains synthetic news stories with question-answer pairs. We use News Stories from repliqa_3 (1035 documents). Each question has exactly one relevant document, so we use MRR for retrieval evaluation.

Results from v0.19.6

Ollama / mxbai-embed-large	Ollama / qwen3:0.6b	0.28	None

Note the significant degradation when very small models are used such as qwen3:0.6b.

Wix

WixQA contains real customer support questions paired with curated answers from Wix. The benchmark follows the evaluation protocol from the WixQA paper. Each query can have multiple relevant passages, so we use MAP for retrieval evaluation.

We benchmark both the plain text version (HTML stripped, no structure) and HTML version. Since HTML chunks are small (typically a phrase), we use chunk_radius=2 to expand context.

HotpotQA

HotpotQA is a multi-hop question answering dataset requiring reasoning over multiple Wikipedia paragraphs. Each question requires evidence from 2+ documents, making it ideal for testing retrieval and reasoning capabilities. We use MAP for retrieval evaluation since queries have multiple relevant documents.

OpenRAG Bench (ORB)

OpenRAG Bench contains ArXiv research papers with multimodal question-answering pairs. Queries include both text-based and image-based questions, testing retrieval over visual content like figures, charts, and diagrams. We use MAP for retrieval evaluation since each query maps to one relevant document.

Multimodal processing: Picture descriptions are generated using a Vision Language Model (VLM) during document conversion, making embedded images searchable via text queries. See Picture Description configuration.
