The full leaderboard tracks 20+ frontier models. For task-specific picks, see coding, reasoning, and agentic.

How to pick for your task

  • Building an agent? Terminal-Bench and SWE-bench are the signals to trust — see /agentic.
  • Writing code? SWE-bench Verified + Aider Polyglot — see /coding.
  • Reasoning-heavy work? GPQA Diamond + ARC-AGI-2 — see /reasoning.
  • High-volume classification? Optimize for cost — see /cheapest.
  • Whole-codebase or long docs? Prioritize context — see /long-context.

FAQ

What is the best LLM right now?
The single best LLM depends on the task. For overall SOTA reasoning, the top of our leaderboard changes weekly — see the current pick above. For coding specifically, see /coding; for long context, /long-context; for cheapest, /cheapest.
How is 'best' decided?
We aggregate LMArena Elo, Artificial Analysis Intelligence Index, LiveBench, GPQA Diamond, SWE-bench Verified, Terminal-Bench, ARC-AGI-2 and Aider Polyglot. No single benchmark decides — the model that leads across the most signals is called SOTA.
Is the best LLM always the most expensive?
Usually yes on output price — flagship reasoning models are the most expensive per token. But for many tasks, a cheaper model at 90% of the quality is a better business choice. Check /cheapest for the price-optimized picks.
