Grok 4.7 vs GPT-6.1 Sol

A side by side look at published price, context window and benchmark scores for these two models. Every number links to its source. A missing field means that model has not published a number for that metric.

What this means for your work

Grok 4.7 costs less for output ($6 vs $10 per 1M tokens, for prompts under 200K tokens) and starts answering sooner at the settings tested. GPT-6.1 Sol holds about twice as much text (1.05 million tokens vs 500,000) and scores higher on the Artificial Analysis index (52 vs 46) and LMArena WebDev. For long documents, Sol fits more; for shorter, output heavy jobs, Grok costs less.
