This comparison puts OpenAI's GPT-5.6 Terra (Max) next to Xiaomi's MiMo-V2.6-Flash. All numbers are the catalogue's recorded values; nobody ran either model by hand for this page. Price separates them more than anything else; on a blended basis GPT-5.6 Terra Max costs 26 times as much as MiMo-V2.6-Flash.

Cost: MiMo-V2.6-Flash is cheaper

The list prices are $2.00 in and $12.00 out for GPT-5.6 Terra Max, and $0.14 in and $0.28 out for MiMo-V2.6-Flash, per million tokens. That makes MiMo-V2.6-Flash's output 98% cheaper.

For a sample workload of 1 million input tokens and 200,000 output tokens, GPT-5.6 Terra Max would cost $4.40 and MiMo-V2.6-Flash $0.20, a difference of $4.20. Scale it up to an agent that reads 50 million tokens and writes 5 million in a month and the bill is $160 for GPT-5.6 Terra Max against $8.40 for MiMo-V2.6-Flash.

GPT-5.6 Terra Max is the faster writer

Measured output speed is 116 tokens per second for GPT-5.6 Terra Max and 36 tokens per second for MiMo-V2.6-Flash. That makes GPT-5.6 Terra Max roughly 3.2 times as fast at writing. Time to first token is 3.4 minutes for GPT-5.6 Terra Max and 3.5 seconds for MiMo-V2.6-Flash. GPT-5.6 Terra Max writes faster once it starts, but MiMo-V2.6-Flash's head start is large enough that MiMo-V2.6-Flash still finishes first at any typical reply length; GPT-5.6 Terra Max only catches up beyond about 10,000 tokens. Waits that long are felt on every chat-style request, though they matter less for batch jobs.

Add the two numbers up for a 400-token reply and MiMo-V2.6-Flash finishes first: 3.5 minutes for GPT-5.6 Terra Max, 15 seconds for MiMo-V2.6-Flash.

GPT-5.6 Terra Max leads on the intelligence index

GPT-5.6 Terra Max comes out ahead on the intelligence index, 32.3 to 26.7. It is a meaningful gap rather than a rounding difference.

For context, that places GPT-5.6 Terra Max 46th and MiMo-V2.6-Flash 64th out of 109 scored models still on offer.

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

Score per dollar

Per point of intelligence index, GPT-5.6 Terra Max costs $0.14 of blended price per million tokens and MiMo-V2.6-Flash $0.0066. MiMo-V2.6-Flash delivers each index point for 95% less; whether GPT-5.6 Terra Max's extra 5.6 points are worth the premium depends on how often your tasks need them.

Release timing

The release dates are July 9, 2026 for GPT-5.6 Terra Max and September 21, 2026 for MiMo-V2.6-Flash, about 2 months apart.
