If you already build on OpenAI, both GPT-6 Astra (Max) and GPT-6 Sol (Max) are on the menu, and they are not interchangeable. Everything below is read from the benchmark, price and speed data in Franklin AI's catalogue; nothing here comes from a hands-on test. Their widest difference is the intelligence index, with GPT-6 Astra Max ahead by 12.7 points (56.9 versus 44.2).

How the intelligence index compares

The catalogue puts GPT-6 Astra Max at 56.9 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 29% more on this index to draw level.

Among 109 active scored models, GPT-6 Astra Max sits 5th and GPT-6 Sol Max 26th.

Neither model has a separate coding or math index recorded yet, so those narrower comparisons will have to wait for more data.

When they came out

GPT-6 Sol Max arrived on September 22, 2026, 19 days after GPT-6 Astra Max (September 3, 2026). They are effectively contemporaries.

Running costs

GPT-6 Astra Max lists $10.00 per million input tokens and $50.00 per million output tokens; GPT-6 Sol Max lists $2.00 and $10.00. For output tokens, GPT-6 Astra Max is 5 times the price of GPT-6 Sol Max.

Take 1 million input tokens and 200,000 output tokens: that comes to $20.00 on GPT-6 Astra Max and $4.00 on GPT-6 Sol Max. Scale it up to extracting fields from 20,000 pages of 1,500 tokens into 150-token records and the bill is $450 for GPT-6 Astra Max against $90.00 for GPT-6 Sol Max. On a 3:1 blend of input to output tokens, that works out to $20.00 versus $4.00 per million.

Is the price in proportion?

Per point of intelligence index, GPT-6 Astra Max costs $0.35 of blended price per million tokens and GPT-6 Sol Max $0.090. GPT-6 Sol Max delivers each index point for 74% less; whether GPT-6 Astra Max's extra 12.7 points are worth the premium depends on how often your tasks need them.

GPT-6 Sol Max is the faster writer

GPT-6 Astra Max generates about 46 tokens per second and GPT-6 Sol Max about 127 tokens per second. That makes GPT-6 Sol Max roughly 2.8 times as fast at writing. The wait for the first token averages 6.8 minutes on GPT-6 Astra Max against 91 seconds on GPT-6 Sol Max. GPT-6 Astra Max waits 4.5 times as long before its first token. A first-token wait of that length suits background work better than live conversation.

Put together, an 800-token answer would take about 7.1 minutes from GPT-6 Astra Max and 97 seconds from GPT-6 Sol Max, counting the first-token wait.

Common questions about GPT-6 Astra Max and GPT-6 Sol Max

Is GPT-6 Astra Max better than GPT-6 Sol Max?

Not across the board: GPT-6 Astra Max scores higher on the intelligence index, 56.9 to 44.2; GPT-6 Sol Max is 80% cheaper on blended price; and GPT-6 Sol Max streams output 2.8 times as fast.

When were GPT-6 Astra Max and GPT-6 Sol Max released?

GPT-6 Sol Max is newer. It was released on September 22, 2026, 19 days after GPT-6 Astra Max (September 3, 2026).

Which model has lower latency?

GPT-6 Sol Max generates output faster, at 127 tokens per second against 46 tokens per second. GPT-6 Sol Max reaches its first token sooner (91 seconds against 6.8 minutes).

Which is cheaper, GPT-6 Astra Max or GPT-6 Sol Max?

GPT-6 Sol Max is cheaper on a blended basis. GPT-6 Astra Max lists $10.00 per million input tokens and $50.00 per million output tokens; GPT-6 Sol Max lists $2.00 and $10.00. For 1 million input and 200,000 output tokens that is $20.00 against $4.00.

Where do these numbers come from?

The figures are the recorded benchmark, price and speed data in Franklin AI's model catalogue. This page is written from that data automatically; neither model was tested by hand for it.

Final whistle

GPT-6 Sol Max is the stronger all-round pick on this data, while GPT-6 Astra Max makes sense in narrower cases. Pick GPT-6 Astra Max if you need the higher overall score (56.9 against 44.2). Pick GPT-6 Sol Max if cost matters ($10.00 against $50.00 per million output tokens) and long outputs need to finish quickly.

Where the numbers come from

The scores, speed and prices in this comparison come from independent third-party model evaluations that Franklin AI syncs each day, and the article was written from a snapshot of them.
