OpenMark — AI Model Benchmarking Platform
Stop trusting leaderboards. Benchmark your own work.
OpenMark lets you benchmark 100+ AI models on your own tasks with deterministic scoring, stability metrics, and real API cost tracking.
What Makes OpenMark Different
- Your tasks, not generic tests — Write any evaluation task (code review, classification, creative writing, vision analysis) and test models against it
- Deterministic scoring — Same prompt, same score, every time. No vibes-based evaluation
- Stability metrics — See which models change their answer across runs (hint: many do)
- Real API costs — Know exactly what each model costs per task, not just per million tokens
- 100+ models — OpenAI, Anthropic, Google, Meta, Mistral, xAI, and more. Side-by-side comparison
Why It Matters
Generic benchmarks (MMLU, HumanEval, MATH) test models on tasks you'll never use. The only benchmark that matters is yours: does this model, with this prompt, for this task, give you the result you expect — reliably and affordably?
