Artificial Analysis: Claude Sonnet 5.5, GPT-6.1 Sol and Gemini 4 Argon Top Coding Agent Index but Costs Vary
Artificial Analysis released the Coding Agent Index, where Claude Sonnet 5.5 (max) in Claude Code tops with 68 points and the highest cost per task at $14.19. Gemini 4 Argon (high) in Antigravity CLI scores 64 at $5.84 per task, under half the cost, but uses promotional pricing and is not yet public. GPT-6.1 Sol (xhigh) in Codex scores 63 at $1.04 per task, about one-sixth of Argon's cost.
- for who
- Teams and developers comparing AI coding agents on performance and price
- why now
- New model releases with varying costs offer timely performance-to-price tradeoffs.
- what changes
- They can weigh the trade-off between benchmark scores and per-task costs to choose a more cost-effective agent
- to do
- Check the Coding Agent Index and compare the listed models' costs for your own coding workloads

score
score 8 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
