Code Arena uses a crowdsourced Elo rating system to judge models on real-world front-end coding tasks through community voting. So this isn’t a tiny sample size: the platform has logged more than 650,000 votes. And unlike old fixed-dataset benchmarks, it leans on multi-step reasoning, tool use, and iterative coding workflows.
GPT-6 Astra and Claude Fable 5.1 are priced the same: $10 per million input tokens and $50 per million output tokens, plus a 1 million token context window.
