GPT-6.1 Sol (Max) (OpenAI) and Grok 4.7 (Xhigh) (SpaceXAI) are not peers on the headline index, which makes the trade-offs the interesting part. No hands-on testing went into this write-up; it summarises the recorded benchmark, price and speed data for both models. The headline gap is on the intelligence index, where GPT-6.1 Sol Max scores 54.6 and Grok 4.7 Xhigh 35.5.

The headline benchmark

GPT-6.1 Sol Max records 54.6 on the intelligence index and Grok 4.7 Xhigh records 35.5. These scores put the two models in different leagues on overall capability.

For context, that places GPT-6.1 Sol Max 8th and Grok 4.7 Xhigh 38th out of 109 scored models still on offer.

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

Token pricing and a sample bill

Per million tokens, GPT-6.1 Sol Max charges $2.00 for input and $10.00 for output, while Grok 4.7 Xhigh charges $2.00 and $6.00. GPT-6.1 Sol Max costs 1.7 times as much per output token.

For a sample workload of 1 million input tokens and 200,000 output tokens, GPT-6.1 Sol Max would cost $4.00 and Grok 4.7 Xhigh $3.20, a difference of $0.80. Scale it up to summarising 1,000 documents of 8,000 tokens into 400-token summaries and the bill is $20.00 for GPT-6.1 Sol Max against $18.40 for Grok 4.7 Xhigh.

Value for money

A blunt value measure, blended price over intelligence score, puts GPT-6.1 Sol Max at $0.073 and Grok 4.7 Xhigh at $0.085 per point. GPT-6.1 Sol Max scores higher and costs less per point, so on price per point there is nothing to trade off.

Throughput and time to first token

GPT-6.1 Sol Max generates about 60 tokens per second and Grok 4.7 Xhigh about 65 tokens per second. On long outputs, that is a real advantage for Grok 4.7 Xhigh. The wait for the first token averages 5.4 minutes on GPT-6.1 Sol Max against 43 seconds on Grok 4.7 Xhigh. In an interactive app, Grok 4.7 Xhigh will feel noticeably more responsive. Waits that long are felt on every chat-style request, though they matter less for batch jobs.

Put together, a 600-token answer would take about 5.6 minutes from GPT-6.1 Sol Max and 52 seconds from Grok 4.7 Xhigh, counting the first-token wait.

Release timing

Grok 4.7 Xhigh came first, on September 21, 2026; GPT-6.1 Sol Max followed on September 29, 2026. That is close enough to count them as the same generation.
