GPT-6 Sol (Max) (OpenAI) and Muse Spark 1.3 (Max) (Meta) meet here on their recorded benchmark, price and speed data. This page is written automatically from catalogue numbers only: benchmark scores, list prices and measured speed. The biggest separation is in overall capability: 44.2 for GPT-6 Sol Max against 36.6 for Muse Spark 1.3 Max.

How the intelligence index compares

GPT-6 Sol Max comes out ahead on the intelligence index, 44.2 to 36.6. That is a clear margin for an index that averages many evaluations. Put another way, Muse Spark 1.3 Max would need 21% more on this index to draw level.

Among 109 active scored models, GPT-6 Sol Max sits 26th and Muse Spark 1.3 Max 36th.

There are no coding or math index scores for either model in the catalogue, which keeps this comparison at the aggregate level.

How fast they respond

Measured output speed is 127 tokens per second for GPT-6 Sol Max and 140 tokens per second for Muse Spark 1.3 Max. Muse Spark 1.3 Max is ahead by 10% on throughput. Before any text appears, GPT-6 Sol Max takes 91 seconds and Muse Spark 1.3 Max 36 seconds. GPT-6 Sol Max waits 2.5 times as long before its first token. A first-token wait of that length suits background work better than live conversation.

For a 2,000-token response, first token plus generation comes to roughly 107 seconds on GPT-6 Sol Max and 50 seconds on Muse Spark 1.3 Max.

Generation gap

Muse Spark 1.3 Max came first, on September 2, 2026; GPT-6 Sol Max followed on September 22, 2026. They are effectively contemporaries.

Cost: Muse Spark 1.3 Max is cheaper

GPT-6 Sol Max lists $2.00 per million input tokens and $10.00 per million output tokens; Muse Spark 1.3 Max lists $1.25 and $4.25. That makes Muse Spark 1.3 Max's output 57% cheaper.

For a sample workload of 1 million input tokens and 200,000 output tokens, GPT-6 Sol Max would cost $4.00 and Muse Spark 1.3 Max $2.10, a difference of $1.90. Scale it up to a month of coding-assistant traffic at 30 million input and 3 million output tokens and the bill is $90.00 for GPT-6 Sol Max against $50.25 for Muse Spark 1.3 Max.

Is the price in proportion?

Per point of intelligence index, GPT-6 Sol Max costs $0.090 of blended price per million tokens and Muse Spark 1.3 Max $0.055. GPT-6 Sol Max costs 1.7 times as much per point, which is the price of its lead.
