GPT-6.1 Sol vs Gemini 4 Argon
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
Both cost the same per token ($2 in, $10 out) and hold about 1.05 million tokens. Gemini 4 Argon is slightly higher on the Artificial Analysis index (53 vs 52) and produces text faster at the settings tested. GPT-6.1 Sol is higher on LMArena WebDev (1749 vs 1674). At the same price, choose by the job: app and site work leans Sol, quicker everyday answers lean Argon.

Output speed
Higher is betterGPT-6.1 Sol: source Artificial Analysis, as of Oct 27, 2026. max; OpenAI API
Gemini 4 Argon: source Artificial Analysis, as of Oct 27, 2026. high; Google API; AA model-page output speed
Time to first token
Lower is betterFor reasoning settings, Artificial Analysis counts thinking time before the first answer token, so long waits are expected on max effort modes.
GPT-6.1 Sol: source Artificial Analysis, as of Oct 27, 2026. max; AA FAQ TTFT, includes thinking on this reasoning setting
Gemini 4 Argon: source Artificial Analysis, as of Oct 27, 2026. high; Google API; AA FAQ label is TTFT; on reasoning models AA sets that equal to time to first answer, so thinking is included
Artificial Analysis Intelligence Index
Higher is betterComposite of several evaluations run by Artificial Analysis at the setting shown.
