Cheap per token, expensive per task: AI model pricing vs. performance [OC]

Reddit r/artificial News

Summary

The article analyzes the cost-effectiveness of AI models like Anthropic's Opus 5.5 and ChatGPT's Astra, using Artificial Analysis scores to compare per-token pricing versus task completion efficiency.

Anthropic's release of Opus 5.5 today sent me down a rabbit hole. I wanted to understand the best effort levels for using this new best-in-class model. That led me to the below, based on Artificial Analysis Intelligence Index v4.3.2 scores. If you look at the first chart, you'll see that in this index Opus 5.5 gets smarter as you dial up the effort level. (That's the result for this scoring model, but it isn't always true: see Best effort level for Opus 5.5) By the first chart, Opus 5.5 is the only model in the best-value quadrant. The second chart shows a different story: what it costs to successfully finish a task. There, ChatGPT's Astra model on xhigh sneaks into the green. It competes head to head with today's best-in-class Opus 5.5 on medium and high effort. Anther thing is the cheap but weaker quadrant. They're only worth the money if you can get accurate results. https://preview.redd.it/lokbgl5xy5rh1.png?width=1472&format=png&auto=webp&s=6379a82e21a7bc72165f25f195516b2e697f9533
