If you only looked at the intelligence index, MiMo-V2.6-Flash and Muse Spark Open (Xhigh) would be hard to tell apart. The clearest gap is on the bill: Muse Spark Open is 11 times the blended price of MiMo-V2.6-Flash. No hands-on testing went into this write-up; it summarises the recorded benchmark, price and speed data for both models.

Price per token

The list prices are $0.14 in and $0.28 out for MiMo-V2.6-Flash, and $1.25 in and $4.25 out for Muse Spark Open, per million tokens. That makes MiMo-V2.6-Flash's output 93% cheaper.

Take 1 million input tokens and 200,000 output tokens: that comes to $0.20 on MiMo-V2.6-Flash and $2.10 on Muse Spark Open. Scale it up to writing 2,000 drafts of 2,000 output tokens from 300-token prompts and the bill is $1.20 for MiMo-V2.6-Flash against $17.75 for Muse Spark Open. On a 3:1 blend of input to output tokens, that works out to $0.175 versus $2.00 per million.

Release timing

Muse Spark Open arrived on October 15, 2026, 24 days after MiMo-V2.6-Flash (September 21, 2026). They are effectively contemporaries.

How fast they respond
