What is ÈwéBench?

ÈwéBench is the first standardized benchmark for evaluating Large Language Models (LLMs) on the Ewe language (ɛʋɛgbɛ) a Kwa language spoken by ~7 million people in Togo and Ghana.

Unlike generic multilingual benchmarks that treat African languages as afterthoughts, ÈwéBench is designed from the ground up for Ewe, with culturally relevant tests, native speaker validation, and evaluation criteria that understand Ewe's unique linguistic features (tonality, agglutination, proverbs).

Why ÈwéBench?

  • No existing benchmark specifically evaluates LLM capabilities in Ewe
  • Generic multilingual benchmarks (MMLU, HellaSwag) don't capture Ewe's nuances
  • African languages need dedicated evaluation tools to track real progress
  • Researchers and developers need a common standard to compare models

Key Features

Feature Description
10 categories From linguistic comprehension to agentic capabilities
107 tests Manually crafted, culturally grounded
Weighted scoring ÈwéScore single metric, weighted by category importance
Any model Works with any OpenAI-compatible API (local or cloud)
CLI & API Run from terminal or integrate into CI/CD
Leaderboard Track and compare model progress
Presets One-command evaluation for Gemini, local models

Quick Start

# Clone the repo
git clone https://github.com/joel710/EweBench.git
cd EweBench

# Install dependencies
pip install -r requirements.txt

# Run with a preset
python run_benchmark.py --preset model --verbose

# Run with a custom endpoint
python run_benchmark.py --endpoint http://localhost:11434/v1/chat/completions \
                        --model yawo-v10 --verbose

# Compare two results
python run_benchmark.py --compare results/model_a.json results/model_b.json

# View leaderboard
python run_benchmark.py --leaderboard

Categories

# Category Tests Weight Description
1 Linguistic Comprehension 15 15% Grammar, vocabulary, tonality, morphology
2 Text Generation 12 15% Fluency, coherence, natural Ewe output
3 Reasoning 12 12% Logical reasoning expressed in Ewe
4 Translation 12 12% Bidirectional FR↔Ewe, EN↔Ewe
5 Cultural Knowledge 10 10% Proverbs, traditions, Ewe/Togolese history
6 Instruction Following 10 10% Complex instruction compliance
7 Multi-turn 8 8% Context coherence across turns
8 Agentic 10 8% Function calling, tool use
9 Style Adaptation 8 5% Register switching (formal/informal)
10 Robustness 10 5% Consistency under adversarial inputs
Total 107 100%

Scoring ÈwéScore

The ÈwéScore is a single number (0-100) representing overall Ewe language capability:

ÈwéScore = Σ (category_score × category_weight) / Σ active_weights

Each test is scored 0.0-1.0 using evaluation methods:

  • exact_match Normalized string comparison
  • keywords Presence of expected Ewe keywords
  • multiple_choice QCM answer detection
  • format Output format compliance (markdown, function_call, etc.)
  • ewe_quality Heuristic Ewe linguistic quality (character usage, vocabulary, structure)
  • composite Weighted combination of multiple methods

Passing threshold: A test is "passed" if score ≥ 0.7

Evaluation Methods

Method Use case How it works
exact_match Factual QA Normalized comparison with expected answer
keywords Open-ended Checks presence of expected Ewe keywords in response
multiple_choice QCM Detects correct answer letter (A/B/C/D)
format Structured output Validates format (markdown, function_call, length)
ewe_quality Free generation Scores Ewe character usage, vocabulary, sentence structure
composite Complex tests Average of keywords + ewe_quality + format

API Compatibility

ÈwéBench works with any API implementing the OpenAI chat completions format:

POST /v1/chat/completions
{
  "model": "model-name",
  "messages": [{"role": "user", "content": "..."}],
  "temperature": 0.3,
  "max_tokens": 1024
}

Tested providers:

  • Openai SDK
  • Google Gemini (OpenAI-compatible endpoint)
  • Ollama (local)
  • vLLM (local)
  • Any OpenAI-compatible server

Qu'est-ce qu'ÈwéBench ?

ÈwéBench est le premier benchmark standardisé pour évaluer les grands modèles de langage (LLMs) sur la langue Ewe (ɛʋɛgbɛ) une langue Kwa parlée par ~7 millions de personnes au Togo et au Ghana.

Contrairement aux benchmarks multilingues génériques qui traitent les langues africaines comme des détails, ÈwéBench est conçu de zéro pour l'Ewe, avec des tests culturellement pertinents, une validation par des locuteurs natifs, et des critères d'évaluation qui comprennent les particularités linguistiques de l'Ewe (tonalité, agglutination, proverbes).

Pourquoi ÈwéBench ?

  • Aucun benchmark existant n'évalue spécifiquement les capacités LLM en Ewe
  • Les benchmarks multilingues génériques (MMLU, HellaSwag) ne capturent pas les nuances de l'Ewe
  • Les langues africaines ont besoin d'outils d'évaluation dédiés pour mesurer les vrais progrès
  • Les chercheurs et développeurs ont besoin d'un standard commun pour comparer les modèles

Catégories

# Catégorie Tests Poids Description
1 Compréhension Linguistique 15 15% Grammaire, vocabulaire, tons, morphologie
2 Génération de Texte 12 15% Fluence, cohérence, naturel du texte Ewe
3 Raisonnement 12 12% Raisonnement logique exprimé en Ewe
4 Traduction 12 12% Bidirectionnelle FR↔Ewe, EN↔Ewe
5 Connaissance Culturelle 10 10% Proverbes, traditions, histoire Ewe/togolaise
6 Suivi d'Instructions 10 10% Respect d'instructions complexes
7 Multi-tour 8 8% Cohérence contextuelle sur plusieurs échanges
8 Agentique 10 8% Function calling, utilisation d'outils
9 Adaptation Stylistique 8 5% Registres formel/informel, technique/simple
10 Robustesse 10 5% Cohérence face aux entrées adverses
Total 107 100%

Scoring ÈwéScore

L'ÈwéScore est un nombre unique (0-100) représentant la capacité globale en Ewe :

ÈwéScore = Σ (score_catégorie × poids_catégorie) / Σ poids_actifs

Seuil de réussite : Un test est "réussi" si le score ≥ 0.7
