Two OpenAI models meet here: GPT-6 Luna (Max) and GPT-6 Sol (Max). The clearest gap is on the bill: GPT-6 Sol Max is 20 times the blended price of GPT-6 Luna Max. No hands-on testing went into this write-up; it summarises the recorded benchmark, price and speed data for both models.

What they cost

Per million tokens, GPT-6 Luna Max charges $0.10 for input and $0.50 for output, while GPT-6 Sol Max charges $2.00 and $10.00. That makes GPT-6 Luna Max's output 95% cheaper.

Take 1 million input tokens and 200,000 output tokens: that comes to $0.20 on GPT-6 Luna Max and $4.00 on GPT-6 Sol Max. A bigger example, extracting fields from 20,000 pages of 1,500 tokens into 150-token records, costs $4.50 on GPT-6 Luna Max and $90.00 on GPT-6 Sol Max: a gap of $85.50. Blended at three input tokens per output token, the effective rates are $0.20 for GPT-6 Luna Max and $4.00 for GPT-6 Sol Max.

GPT-6 Sol Max leads on the intelligence index

The catalogue puts GPT-6 Luna Max at 27.9 and GPT-6 Sol Max at 44.2 on its intelligence index. A gap this large suggests the two are built for different jobs. Put another way, GPT-6 Luna Max would need 58% more on this index to draw level.

For context, that places GPT-6 Luna Max 62nd and GPT-6 Sol Max 26th out of 109 scored models still on offer.

The catalogue does not yet split either model's score into coding and math indexes.

Waiting time

Measured output speed is 121 tokens per second for GPT-6 Luna Max and 127 tokens per second for GPT-6 Sol Max. There is little to choose between them on raw output speed. The wait for the first token averages 2.0 minutes on GPT-6 Luna Max against 91 seconds on GPT-6 Sol Max. GPT-6 Luna Max waits 1.3 times as long before its first token. A first-token wait of that length suits background work better than live conversation.

Put together, a 1,500-token answer would take about 2.2 minutes from GPT-6 Luna Max and 103 seconds from GPT-6 Sol Max, counting the first-token wait.

Release timing

GPT-6 Luna Max and GPT-6 Sol Max share a release date: September 22, 2026. OpenAI released them together, so neither is an older generation.

Is the price in proportion?

A blunt value measure, blended price over intelligence score, puts GPT-6 Luna Max at $0.0072 and GPT-6 Sol Max at $0.090 per point. So GPT-6 Sol Max buys its higher score at a premium, while GPT-6 Luna Max is the value pick, paying 92% less per point.

FAQ

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

It depends on what you need: GPT-6 Sol Max scores higher on the intelligence index, 44.2 to 27.9; GPT-6 Luna Max is 95% cheaper on blended price; and GPT-6 Sol Max reaches its first token sooner.

Was this comparison tested by hand?

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.

Who makes GPT-6 Luna Max and GPT-6 Sol Max?

Both are OpenAI models, listed as separate models in the catalogue. GPT-6 Luna Max was released on September 22, 2026 and GPT-6 Sol Max on September 22, 2026.

Does GPT-6 Luna Max respond faster than GPT-6 Sol Max?

Their output speeds are close: 121 tokens per second for GPT-6 Luna Max and 127 tokens per second for GPT-6 Sol Max. GPT-6 Sol Max reaches its first token sooner (91 seconds against 2.0 minutes).

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

GPT-6 Luna Max is cheaper on a blended basis. GPT-6 Luna Max lists $0.10 per million input tokens and $0.50 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 $0.20 against $4.00.

Final whistle

In one line: on balance the numbers favour GPT-6 Sol Max, though GPT-6 Luna Max keeps a case of its own. Pick GPT-6 Luna Max if cost matters ($0.50 against $10.00 per million output tokens). Pick GPT-6 Sol Max if you need the higher overall score (44.2 against 27.9) and users are waiting on the first word.

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.
