How the intelligence index compares

Claude Opus 5 Max comes out ahead on the intelligence index, 44.2 to 35.5. This is a substantial lead, not a near miss.

For context, that places Claude Opus 5 Max 26th and Grok 4.7 Xhigh 38th out of 109 scored models still on offer.

The catalogue does not yet split either model's score into coding and math indexes.

Running costs

Claude Opus 5 Max lists $5.00 per million input tokens and $25.00 per million output tokens; Grok 4.7 Xhigh lists $2.00 and $6.00. For output tokens, Claude Opus 5 Max is 4.2 times the price of Grok 4.7 Xhigh.

Take 1 million input tokens and 200,000 output tokens: that comes to $10.00 on Claude Opus 5 Max and $3.20 on Grok 4.7 Xhigh. Scale it up to extracting fields from 20,000 pages of 1,500 tokens into 150-token records and the bill is $225 for Claude Opus 5 Max against $78.00 for Grok 4.7 Xhigh. On a 3:1 blend of input to output tokens, that works out to $10.00 versus $3.00 per million.
