Questions people ask
Which is better, GPT-5.6 Sol or Grok 4.7?
GPT-5.6 Sol wins seven of the eight areas we test: coding, agents, reasoning, facts, images and charts, math and long documents. Grok 4.7 wins following instructions, and costs 67% less.
Which is better for coding?
GPT-5.6 Sol. It wins 2 of the 4 coding tests both models report; Grok 4.7 wins 1, and 1 is a tie.
Which is cheaper?
GPT-5.6 Sol costs $4.00 per million input tokens and $20.00 per million output tokens; Grok 4.7 costs $2.00 and $6.00. That makes Grok 4.7 about 67% cheaper for the same work.
How do you compare the two?
We use the 31 benchmark tests both models have published scores on. The verdict counts the 21 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 10 are listed but not counted, because several are summary scores or repeat a test. Each score is the one shown on the model's own page.
