Artificial Analysis published its Coding Agent Index evaluating model and harness combinations. Claude Sonnet 5.5 in Claude Code leads with 68 at $14.19 per task, while GPT-6.1 Sol in Codex achieves 63 for $1.04.
Why it matters. Developers can lower agent orchestration bills by up to 93% by routing routine implementation tasks to Codex instead of Claude Code.
