Complementary text-LLM evaluation: cost + latency + hallucination tracking

Hi OpenCompass team ๐Ÿ‘‹

Your VLM leaderboard is the reference for vision-language benchmarking. For teams who also need to evaluate the text-only LLM backbone of their VLMs, I built a complementary tool.

LLM Evaluation Framework covers the text evaluation side with 5 simultaneous metrics:

โ†’ ๐ŸŽฏ Accuracy on MMLU + TruthfulQA benchmarks
โ†’ โšก Latency โ€” full percentile breakdown (p50/p75/p90/p95/p99)
โ†’ ๐Ÿ’ฐ Cost โ€” precise per-1K-token pricing for every major provider
โ†’ ๐Ÿ” Hallucination Rate โ€” runs locally, zero additional cost
โ†’ ๐Ÿง  Reasoning Quality โ€” structured chain-of-thought scoring

One CLI command. Any LiteLLM-compatible model. Full PDF + JSON report.

Open source, free forever. Would love feedback from the OpenCompass community on benchmark design!
