This comparison puts SpaceXAI's Grok 4.7 (Xhigh) next to Thinking Machines's Inkling 2 Small. The clearest gap is on the bill: Grok 4.7 Xhigh is 6.3 times the blended price of Inkling 2 Small. Everything below is read from the benchmark, price and speed data in Franklin AI's catalogue; nothing here comes from a hands-on test.

Token pricing and a sample bill

Grok 4.7 Xhigh lists $2.00 per million input tokens and $6.00 per million output tokens; Inkling 2 Small lists $0.30 and $1.00. Grok 4.7 Xhigh costs 6 times as much per output token.

Take 1 million input tokens and 200,000 output tokens: that comes to $3.20 on Grok 4.7 Xhigh and $0.50 on Inkling 2 Small. Scale it up to summarising 1,000 documents of 8,000 tokens into 400-token summaries and the bill is $18.40 for Grok 4.7 Xhigh against $2.80 for Inkling 2 Small. On a 3:1 blend of input to output tokens, that works out to $3.00 versus $0.475 per million.

Reasoning and overall scores

Grok 4.7 Xhigh records 35.5 on the intelligence index and Inkling 2 Small records 30.6. That is a clear margin for an index that averages many evaluations. In relative terms, Grok 4.7 Xhigh scores 16% higher.

Across the 109 active models with an intelligence score in the catalogue, Grok 4.7 Xhigh ranks 38th and Inkling 2 Small ranks 52nd.

Specialist coding and math indexes are missing for both, so treat the overall score as the only capability signal here.

Release timing

Inkling 2 Small arrived on November 5, 2026, about a month after Grok 4.7 Xhigh (September 21, 2026). That is close enough to count them as the same generation.

Score per dollar

A blunt value measure, blended price over intelligence score, puts Grok 4.7 Xhigh at $0.085 and Inkling 2 Small at $0.016 per point. So Grok 4.7 Xhigh buys its higher score at a premium, while Inkling 2 Small is the value pick, paying 82% less per point.

Waiting time

Measured output speed is 65 tokens per second for Grok 4.7 Xhigh and 139 tokens per second for Inkling 2 Small. That makes Inkling 2 Small roughly 2.1 times as fast at writing. Before any text appears, Grok 4.7 Xhigh takes 43 seconds and Inkling 2 Small 2.2 seconds. Grok 4.7 Xhigh waits 19 times as long before its first token. A first-token wait of that length suits background work better than live conversation.

Put together, an 800-token answer would take about 55 seconds from Grok 4.7 Xhigh and 8.0 seconds from Inkling 2 Small, counting the first-token wait.
