Best LLM for every task

The right model depends on the job. Each guide below picks the cheapest model that’s still smart enough for that task — ranked by community Arena score and price — so you don’t overpay for capability you can’t use.

Coding Arena
Best LLM for Coding

The best value LLMs for writing and debugging code, ranked by coding Arena score and price. See the cheapest model that's still strong at code.

Overall Arena

Overall Arena
Best LLM for High-Volume Classification

The best value LLMs for high-volume classification and tagging, ranked by cost with a sane quality bar. Tiny outputs make price per call tiny — volume makes it add up.

Best model for your coding tool

Editors and agents like Cursor, Copilot and Aider let you choose the underlying model. These guides rank the models each tool supports by coding value, so you spend your request pool (or your API bill) where it counts.

Intelligence scores are community Arena ratings from LMArena / arena.ai, used under CC BY 4.0. Snapshot last refreshed 28 July 2026. Scores are a relative signal, not an absolute measure of capability. A Measured score was voted on directly; an Estimated score is inherited from an identical base model (a regional/creator-prefixed hosting duplicate). See our methodology.
