Find and understand every LLM. Compare 300+ models by benchmark, speed, latency, price, context and capability — in one place.
modelgrep aggregates OpenRouter's catalog with independent benchmarks, live performance and pricing so you can compare large language models by intelligence, speed, latency, cost, context and capability.
- Leaderboard — every model, filterable by capability (reasoning, tools, vision, JSON), price, context and provider, sortable on any metric.
- Rankings — data-backed "best LLM for X" pages: smartest, coding, design, fastest, cheapest, free, reasoning, vision, agents, long-context, open-source — and each scoped per maker (e.g. fastest Anthropic model).
- Compare — side-by-side model vs. model.
- Makers & model pages — per-provider breakdowns with live throughput, latency, uptime and per-endpoint pricing.
- Free public API — the same data as read-only JSON, no key required.

Performance refreshes hourly; benchmarks daily. All enrichment is cached so the heavy fan-out runs once per revalidate window.
