Claude Haiku 5.5 Max vs Grok 4.7 Xhigh: which is cheaper?

There is very little daylight between Claude Haiku 5.5 (Max) (Anthropic) and Grok 4.7 (Xhigh) (SpaceXAI) on the overall index. No hands-on testing went into this write-up; it summarises the recorded benchmark, price and speed data for both models. Price separates them more than anything else; on a blended basis Grok 4.7 Xhigh costs 15 times as much as Claude Haiku 5.5 Max.

Token pricing and a sample bill

The list prices are $0.10 in and $0.50 out for Claude Haiku 5.5 Max, and $2.00 in and $6.00 out for Grok 4.7 Xhigh, per million tokens. That makes Claude Haiku 5.5 Max's output 92% cheaper.

For a sample workload of 1 million input tokens and 200,000 output tokens, Claude Haiku 5.5 Max would cost $0.20 and Grok 4.7 Xhigh $3.20, a difference of $3.00. A bigger example, a month of coding-assistant traffic at 30 million input and 3 million output tokens, costs $4.50 on Claude Haiku 5.5 Max and $78.00 on Grok 4.7 Xhigh: a gap of $73.50. On a 3:1 blend of input to output tokens, that works out to $0.20 versus $3.00 per million.

How the intelligence index compares

Claude Haiku 5.5 Max comes out ahead on the intelligence index, 36.5 to 35.5. It is a small margin for an index that averages many evaluations.

Across the 109 active models with an intelligence score in the catalogue, Claude Haiku 5.5 Max ranks 37th and Grok 4.7 Xhigh ranks 38th.

Neither model has a separate coding or math index recorded yet, so those narrower comparisons will have to wait for more data.

Which is newer

Claude Haiku 5.5 Max arrived on October 7, 2026, 16 days after Grok 4.7 Xhigh (September 21, 2026). That is close enough to count them as the same generation.

Value for money

A blunt value measure, blended price over intelligence score, puts Claude Haiku 5.5 Max at $0.0055 and Grok 4.7 Xhigh at $0.085 per point. Claude Haiku 5.5 Max scores higher and costs less per point, so on price per point there is nothing to trade off.

Claude Haiku 5.5 Max is the faster writer

Once a response is under way, Claude Haiku 5.5 Max produces roughly 233 tokens per second against 65 tokens per second for Grok 4.7 Xhigh. That makes Claude Haiku 5.5 Max roughly 3.6 times as fast at writing. Before any text appears, Claude Haiku 5.5 Max takes 4.6 minutes and Grok 4.7 Xhigh 43 seconds. Claude Haiku 5.5 Max writes faster once it starts, but Grok 4.7 Xhigh's head start is large enough that Grok 4.7 Xhigh still finishes first at any typical reply length; Claude Haiku 5.5 Max only catches up beyond about 21,000 tokens. A first-token wait of that length suits background work better than live conversation.

For a 600-token response, first token plus generation comes to roughly 4.7 minutes on Claude Haiku 5.5 Max and 52 seconds on Grok 4.7 Xhigh.
