Cost vs Coding Index

122 priced models
Most attractive quadrant (cheap + high)
= reasoning model (extended thinking)

Each labelled name links to that model’s page. Curated to the cost-efficiency frontier, top scorers and cheapest so labels stay readable; the full field is in the leaderboard table below (and via “select all”). Reasoning models (extended “thinking” before answering) carry a ring around the dot.

Frequently asked questions

What is the Coding Index benchmark?

Artificial Analysis's composite coding score (0 to 100), averaging coding evaluations such as Terminal-Bench (terminal-based software-engineering and sysadmin tasks) and SciCode (scientific-computing Python problems) and normalising to a 0 to 100 scale. Higher means stronger overall coding performance.

Which AI model scores highest on Coding Index?

Claude Fable 5.1 (Anthropic) leads with 81.6, from $10.00 per 1M input tokens from Anthropic. Artificial Analysis last published scores for this benchmark on Sep 9, 2026. Scores here are frozen at that date, and models released since are not on it.

How many models are ranked on Coding Index?

185 models carry a Coding Index score. Scores come from Artificial Analysis; where a model has a listed API price it is drawn from LiteLLM and OpenRouter, and models with no current price are listed without one.
