Compare AI Models
Head-to-head AI model comparisons on the un-leaked meo benchmark. Each matchup lays out accuracy, Effective Value (π), cost per correct answer, speed, context, and pricing side by side β because the winner changes with the metric you care about.
Frequently asked questions
How should I compare two AI models?
Compare on the dimension your workload needs: raw accuracy for correctness, Effective Value (π) for deep agentic chains, cost-per-correct-answer for budget, and speed for latency. The same two models can swap places depending on which metric you weight.
Are these comparisons based on public benchmarks?
No β the head-to-head figures come from the un-leaked, contamination-resistant meo benchmark (a private holdout), cross-referenced with attributed third-party signals. Public benchmarks can be memorized; meo cannot.
