Gemini 4 Argon vs Grok 4.7 Xhigh: benchmarks, price and speed

Gemini 4 Argon (High) from Google and Grok 4.7 (Xhigh) from SpaceXAI sit in different tiers of the catalogue. Gemini 4 Argon leads the intelligence index 50.4 to 35.5, a gap of 14.9 points. What follows is built entirely from tracked data, so where the catalogue is silent, this page says so instead of guessing.

Gemini 4 Argon leads on the intelligence index

Gemini 4 Argon comes out ahead on the intelligence index, 50.4 to 35.5. A difference this size usually separates one tier of model from the next. Put another way, Grok 4.7 Xhigh would need 42% more on this index to draw level.

For context, that places Gemini 4 Argon 15th 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, Gemini 4 Argon charges $4.00 for input and $20.00 for output, while Grok 4.7 Xhigh charges $2.00 and $6.00. That makes Grok 4.7 Xhigh's output 70% cheaper.

Take 1 million input tokens and 200,000 output tokens: that comes to $8.00 on Gemini 4 Argon and $3.20 on Grok 4.7 Xhigh. For a support assistant answering 10,000 conversations of 2,000 input and 500 output tokens each, Grok 4.7 Xhigh would come in 61% lower: $180 for Gemini 4 Argon against $70.00 for Grok 4.7 Xhigh. On a 3:1 blend of input to output tokens, that works out to $8.00 versus $3.00 per million.

Value for money

Per point of intelligence index, Gemini 4 Argon costs $0.16 of blended price per million tokens and Grok 4.7 Xhigh $0.085. Grok 4.7 Xhigh delivers each index point for 47% less; whether Gemini 4 Argon's extra 14.9 points are worth the premium depends on how often your tasks need them.

Gemini 4 Argon is the faster writer

Gemini 4 Argon generates about 89 tokens per second and Grok 4.7 Xhigh about 65 tokens per second. That makes Gemini 4 Argon roughly 1.4 times as fast at writing. Time to first token is 51 seconds for Gemini 4 Argon and 43 seconds for Grok 4.7 Xhigh. Short replies favour Grok 4.7 Xhigh; beyond about 1,900 tokens, Gemini 4 Argon claws the time back. A first-token wait of that length suits background work better than live conversation.

Add the two numbers up for a 2,000-token reply and Gemini 4 Argon finishes first: 73 seconds for Gemini 4 Argon, 74 seconds for Grok 4.7 Xhigh.

When they came out

Gemini 4 Argon arrived on September 30, 2026, 9 days after Grok 4.7 Xhigh (September 21, 2026). That is close enough to count them as the same generation.
