GPT-6.1 Sol Max vs GPT-6 Sol Max: benchmark scores compared

If you already build on OpenAI, both GPT-6.1 Sol (Max) and GPT-6 Sol (Max) are on the menu, and they are not interchangeable. Their widest difference is the intelligence index, with GPT-6.1 Sol Max ahead by 10.4 points (54.6 versus 44.2). What follows is built entirely from tracked data, so where the catalogue is silent, this page says so instead of guessing.

GPT-6.1 Sol Max leads on the intelligence index

The catalogue puts GPT-6.1 Sol Max at 54.6 and GPT-6 Sol Max at 44.2 on its intelligence index. A difference this size usually separates one tier of model from the next. Put another way, GPT-6 Sol Max would need 24% more on this index to draw level.

Across the 109 active models with an intelligence score in the catalogue, GPT-6.1 Sol Max ranks 8th and GPT-6 Sol Max ranks 26th.

Specialist coding and math indexes are missing for both, so treat the overall score as the only capability signal here.

Throughput and time to first token

Measured output speed is 60 tokens per second for GPT-6.1 Sol Max and 127 tokens per second for GPT-6 Sol Max. On long outputs, that is a real advantage for GPT-6 Sol Max. The wait for the first token averages 5.4 minutes on GPT-6.1 Sol Max against 91 seconds on GPT-6 Sol Max. In an interactive app, GPT-6 Sol Max will feel noticeably more responsive. Waits that long are felt on every chat-style request, though they matter less for batch jobs.

Put together, a 1,500-token answer would take about 5.8 minutes from GPT-6.1 Sol Max and 103 seconds from GPT-6 Sol Max, counting the first-token wait.

Generation gap

GPT-6 Sol Max came first, on September 22, 2026; GPT-6.1 Sol Max followed on September 29, 2026. They are effectively contemporaries.

Pricing: no difference

GPT-6.1 Sol Max lists $2.00 per million input tokens and $10.00 per million output tokens; GPT-6 Sol Max lists $2.00 and $10.00. Neither is cheaper; the price sheets match exactly.

Score per dollar

A blunt value measure, blended price over intelligence score, puts GPT-6.1 Sol Max at $0.073 and GPT-6 Sol Max at $0.090 per point. With the higher score and the lower cost per point, GPT-6.1 Sol Max is the better value per point on these numbers.
