Grok 4.7 vs GPT-6.1 Sol
Grok 4.7 lists at $2 / $6 per 1M tokens and GPT-6.1 Sol at $2 / $10. Grok looks cheaper on output, but cost per finished job tells a different story.
Our verdict
GPT-6.1 Sol is the better default. Artificial Analysis scores it higher (52 against 46) and found Grok 4.7 very verbose, using roughly three times as many output tokens per task as GPT-6 Astra, so a finished job costs more than the rate card suggests. GPT-6.1 Sol also has more than twice the context window (about 1.05 million tokens against 500K). Choose Grok 4.7 when you already work in the xAI, X or Cursor ecosystem; otherwise start with GPT-6.1 Sol. On GPT-6.1 Sol, prompts over 272K input tokens bill at double input and 1.5 times output.
Benchmarks measure test tasks, not your business. Run a real job through both models before you commit.
