GPT-6 Luna (Max) from OpenAI and MiMo-V2.6-Flash from Xiaomi land within 1.2 points of each other on the intelligence index. The biggest gap is output speed, where GPT-6 Luna Max records 121 tokens per second and MiMo-V2.6-Flash 36 tokens per second. Everything below is read from the benchmark, price and speed data in Franklin AI's catalogue; nothing here comes from a hands-on test.

Throughput and time to first token

Once a response is under way, GPT-6 Luna Max produces roughly 121 tokens per second against 36 tokens per second for MiMo-V2.6-Flash. GPT-6 Luna Max is ahead by 237% on throughput. The wait for the first token averages 2.0 minutes on GPT-6 Luna Max against 3.5 seconds on MiMo-V2.6-Flash. That is a genuine trade-off: MiMo-V2.6-Flash starts sooner, while GPT-6 Luna Max finishes first once outputs run beyond about 6,000 tokens. 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 2.3 minutes on GPT-6 Luna Max and 59 seconds on MiMo-V2.6-Flash.

How the intelligence index compares

GPT-6 Luna Max records 27.9 on the intelligence index and MiMo-V2.6-Flash records 26.7. The lead is visible but narrow, so it should not decide the choice on its own.

Across the 109 active models with an intelligence score in the catalogue, GPT-6 Luna Max ranks 62nd and MiMo-V2.6-Flash ranks 64th.

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

Pricing depends on your mix

GPT-6 Luna Max lists $0.10 per million input tokens and $0.50 per million output tokens; MiMo-V2.6-Flash lists $0.14 and $0.28. Neither is cheaper across the board: GPT-6 Luna Max has the lower input rate and MiMo-V2.6-Flash the lower output rate, so the shape of your traffic decides it.

A sample workload of 1 million input tokens and 200,000 output tokens costs about the same on either: $0.20 against $0.20. Scale it up to classifying 100,000 short messages at 150 input tokens and 5 output tokens each and the bill is $1.75 for GPT-6 Luna Max against $2.24 for MiMo-V2.6-Flash.

Release timing

MiMo-V2.6-Flash came first, on September 21, 2026; GPT-6 Luna Max followed on September 22, 2026. They are effectively contemporaries.

Value for money

Dividing the blended price by the intelligence index gives a rough cost per point: $0.0072 for GPT-6 Luna Max and $0.0066 for MiMo-V2.6-Flash, per million tokens. So neither is a bargain relative to the other; you pay for what the index measures.

Quick answers
