Muse Spark 1.1 vs Kimi K2.6: which scores higher on benchmarks?

Muse Spark 1.1 scores 75.3 and Kimi K2.6 scores 70.5 overall on LiveBench, the mean of its seven categories. That is a 4.8-point lead for Muse Spark 1.1. Category scores differ from the overall figure — a model can lead on reasoning and trail on coding, which the per-category table above breaks out.

Which gives better value for money, Muse Spark 1.1 or Kimi K2.6?

Kimi K2.6. Cost per point divides the measured dollars LiveBench spent running the benchmark by the score it earned, so it captures something token pricing misses: a reasoning model can emit many times more tokens than its per-token rate suggests. Muse Spark 1.1 works out at $0.1139 per point and Kimi K2.6 at $0.0918.

Does Muse Spark 1.1 or Kimi K2.6 have a bigger context window?

Muse Spark 1.1 has the larger context window: 1.0M for Muse Spark 1.1 against 262K for Kimi K2.6. Note that a window you can fill is not a window you should fill — retrieval quality usually degrades well before the limit, and you pay for every token you put in it.

Do Muse Spark 1.1 and Kimi K2.6 support prompt caching?

Both publish a cached-input rate: $0.150 per million for Muse Spark 1.1 and $0.094 for Kimi K2.6, against full input rates of $1.25 and $0.560. On a workload with a long stable prefix — a system prompt, a tool schema, a retrieved corpus — that changes the economics more than the headline price does.

How these numbers are produced

  • Price — provider list price from OpenRouter, refreshed every 15 minutes. “Blended” is a 3:1 input:output mix.
  • ScoresLiveBench release 2026-06-25, using their own category map. Each model shows its strongest published run. A blank means “not evaluated”, never “bad”.
  • Cost per point — the measured dollars LiveBench spent on the run, divided by the score it earned.
  • “Win” — awarded only past a threshold: one full point on a benchmark score, 10% on a price, 25% on a context window. Anything tighter reports as a tie, because effort settings alone move a LiveBench score by more than that.
