If you only looked at the intelligence index, GPT-6 Luna (Max) and MiMo-V2.6-Pro would be hard to tell apart. MiMo-V2.6-Pro starts answering far sooner, with a time to first token of 3.0 seconds compared with 2.0 minutes for GPT-6 Luna Max. All numbers are the catalogue's recorded values; nobody ran either model by hand for this page.

GPT-6 Luna Max is the faster writer

Measured output speed is 121 tokens per second for GPT-6 Luna Max and 41 tokens per second for MiMo-V2.6-Pro. GPT-6 Luna Max is ahead by 194% on throughput. Before any text appears, GPT-6 Luna Max takes 2.0 minutes and MiMo-V2.6-Pro 3.0 seconds. Short replies favour MiMo-V2.6-Pro; beyond about 7,400 tokens, GPT-6 Luna Max claws the time back. Waits that long are felt on every chat-style request, though they matter less for batch jobs.

Add the two numbers up for a 1,500-token reply and MiMo-V2.6-Pro finishes first: 2.2 minutes for GPT-6 Luna Max, 40 seconds for MiMo-V2.6-Pro.

Token pricing and a sample bill

Per million tokens, GPT-6 Luna Max charges $0.10 for input and $0.50 for output, while MiMo-V2.6-Pro charges $0.435 and $0.87. That makes GPT-6 Luna Max's output 43% cheaper.

Take 1 million input tokens and 200,000 output tokens: that comes to $0.20 on GPT-6 Luna Max and $0.61 on MiMo-V2.6-Pro. For a month of coding-assistant traffic at 30 million input and 3 million output tokens, GPT-6 Luna Max would come in 71% lower: $4.50 for GPT-6 Luna Max against $15.66 for MiMo-V2.6-Pro.

Generation gap

GPT-6 Luna Max arrived on September 22, 2026, one day after MiMo-V2.6-Pro (September 21, 2026). They are effectively contemporaries.

Benchmark scores

The catalogue puts GPT-6 Luna Max at 27.9 and MiMo-V2.6-Pro at 29.9 on its intelligence index. That is a modest edge: real, but small enough that the right set of tasks could reverse it. In relative terms, MiMo-V2.6-Pro scores 7% higher.

Across the 109 active models with an intelligence score in the catalogue, GPT-6 Luna Max ranks 62nd and MiMo-V2.6-Pro ranks 55th.

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

Is the price in proportion?

A blunt value measure, blended price over intelligence score, puts GPT-6 Luna Max at $0.0072 and MiMo-V2.6-Pro at $0.018 per point. MiMo-V2.6-Pro costs 2.5 times as much per point, which is the price of its lead.
