Choosing between Grok 4.6 (Xhigh) and Muse Spark 1.3 (Max) also means choosing between SpaceXAI and Meta. This page is written automatically from catalogue numbers only: benchmark scores, list prices and measured speed. Throughput is the standout difference: 140 tokens per second for Muse Spark 1.3 Max against 62 tokens per second for Grok 4.6 Xhigh.

Waiting time

Measured output speed is 62 tokens per second for Grok 4.6 Xhigh and 140 tokens per second for Muse Spark 1.3 Max. On long outputs, that is a real advantage for Muse Spark 1.3 Max. Before any text appears, Grok 4.6 Xhigh takes 47 seconds and Muse Spark 1.3 Max 36 seconds. Muse Spark 1.3 Max gets to its first token 1.3 times as fast. 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 57 seconds on Grok 4.6 Xhigh and 40 seconds on Muse Spark 1.3 Max.

The headline benchmark

On the intelligence index, Grok 4.6 Xhigh scores 31.0 against 36.6 for Muse Spark 1.3 Max. A lead of this size is hard to dismiss as noise. In relative terms, Muse Spark 1.3 Max scores 18% higher.

For context, that places Grok 4.6 Xhigh 49th and Muse Spark 1.3 Max 36th out of 109 scored models still on offer.

For coding or maths work specifically, the catalogue has no dedicated index on either side yet.

What they cost

Grok 4.6 Xhigh lists $2.00 per million input tokens and $6.00 per million output tokens; Muse Spark 1.3 Max lists $1.25 and $4.25. That makes Muse Spark 1.3 Max's output 29% cheaper.

Take 1 million input tokens and 200,000 output tokens: that comes to $3.20 on Grok 4.6 Xhigh and $2.10 on Muse Spark 1.3 Max. A bigger example, classifying 100,000 short messages at 150 input tokens and 5 output tokens each, costs $33.00 on Grok 4.6 Xhigh and $20.88 on Muse Spark 1.3 Max: a gap of $12.13. On a 3:1 blend of input to output tokens, that works out to $3.00 versus $2.00 per million.

Cost per point of intelligence

Per point of intelligence index, Grok 4.6 Xhigh costs $0.097 of blended price per million tokens and Muse Spark 1.3 Max $0.055. Muse Spark 1.3 Max scores higher and costs less per point, so on price per point there is nothing to trade off.

Release timing

Grok 4.6 Xhigh came first, on August 12, 2026; Muse Spark 1.3 Max followed on September 2, 2026. That is close enough to count them as the same generation.
