"""Quality evaluation for exo — matches Artificial Analysis methodology.
|
|
|
|
Runs LLM benchmarks against exo's OpenAI-compatible API using the same
|
|
prompts, temperature settings, and answer extraction as Artificial Analysis.
|
|
|
|
Supported benchmarks:
|
|
gpqa_diamond - Graduate-level science QA (198 questions, 4-choice MC)
|
|
mmlu_pro - Multi-task language understanding (12K questions, 10-choice MC)
|
|
aime_2024 - Math olympiad 2024 (30 problems, integer answers)
|
|
aime_2025 - Math olympiad 2025 (30 problems, integer answers)
|
|
humaneval - Python code generation (164 problems, pass@1)
|
|
livecodebench - Competitive programming (880+ problems, pass@1)
|
|
|
|
Model configs in eval_configs/models.toml auto-detect reasoning/non-reasoning
|
|
settings per model. Override with --reasoning / --no-reasoning.
|
|
|
|
Usage:
|
|
uv run python exo_eval.py --model <model-id> --tasks gpqa_diamond
|
|
uv run python exo_eval.py --model <model-id> --tasks humaneval,livecodebench --limit 50
|
|
uv run python exo_eval.py --model <model-id> --tasks gpqa_diamond --compare-concurrency 1,4
