Kimi K3.1 Pro vs Muse Wonder Max: speed, latency and cost

Kimi K3.1 Pro and Muse Wonder (Max) are close rivals from Kimi and Meta. The figures come from tracked catalogue data, not from our own testing, so treat them as a starting point for a trial on your tasks. The biggest gap is output speed, where Muse Wonder Max records 134 tokens per second and Kimi K3.1 Pro 27 tokens per second.

Waiting time

Kimi K3.1 Pro generates about 27 tokens per second and Muse Wonder Max about 134 tokens per second. That makes Muse Wonder Max roughly 5 times as fast at writing. Time to first token is 3.0 seconds for Kimi K3.1 Pro and 26 seconds for Muse Wonder Max. That is a genuine trade-off: Kimi K3.1 Pro starts sooner, while Muse Wonder Max finishes first once outputs run beyond about 800 tokens.

Add the two numbers up for a 1,000-token reply and Muse Wonder Max finishes first: 40 seconds for Kimi K3.1 Pro, 33 seconds for Muse Wonder Max.

Running costs

Kimi K3.1 Pro lists $2.00 per million input tokens and $10.00 per million output tokens; Muse Wonder Max lists $4.00 and $20.00. Muse Wonder Max costs twice as much per output token.

A reference job of 1 million input tokens and 200,000 output tokens costs $4.00 with Kimi K3.1 Pro and $8.00 with Muse Wonder Max, so Kimi K3.1 Pro saves $4.00. For an agent that reads 50 million tokens and writes 5 million in a month, Kimi K3.1 Pro would come in 50% lower: $150 for Kimi K3.1 Pro against $300 for Muse Wonder Max.

When they came out

Muse Wonder Max came first, on October 12, 2026; Kimi K3.1 Pro followed on October 23, 2026. That is close enough to count them as the same generation.

How the intelligence index compares

The catalogue puts Kimi K3.1 Pro at 46.5 and Muse Wonder Max at 43.6 on its intelligence index. That is a modest edge: real, but small enough that the right set of tasks could reverse it. Put another way, Muse Wonder Max would need 7% more on this index to draw level.

Across the 109 active models with an intelligence score in the catalogue, Kimi K3.1 Pro ranks 23rd and Muse Wonder Max ranks 28th.

Specialist coding and math indexes are missing for both, so treat the overall score as the only capability signal here.

Score per dollar

Per point of intelligence index, Kimi K3.1 Pro costs $0.086 of blended price per million tokens and Muse Wonder Max $0.18. Kimi K3.1 Pro scores higher and costs less per point, so on price per point there is nothing to trade off.
