How fast they respond

Measured output speed is 121 tokens per second for Gemini 3.8 Flash High and 140 tokens per second for Muse Spark 1.3 Max. That makes Muse Spark 1.3 Max roughly 1.2 times as fast at writing. The wait for the first token averages 27 seconds on Gemini 3.8 Flash High against 36 seconds on Muse Spark 1.3 Max. That is a genuine trade-off: Gemini 3.8 Flash High starts sooner, while Muse Spark 1.3 Max finishes first once outputs run beyond about 7,800 tokens. Waits that long are felt on every chat-style request, though they matter less for batch jobs.

Put together, a 600-token answer would take about 32 seconds from Gemini 3.8 Flash High and 40 seconds from Muse Spark 1.3 Max, counting the first-token wait.

Price per token

Gemini 3.8 Flash High lists $0.75 per million input tokens and $3.75 per million output tokens; Muse Spark 1.3 Max lists $1.25 and $4.25. Muse Spark 1.3 Max costs 1.1 times as much per output token.

For a sample workload of 1 million input tokens and 200,000 output tokens, Gemini 3.8 Flash High would cost $1.50 and Muse Spark 1.3 Max $2.10, a difference of $0.60. Scale it up to an agent that reads 50 million tokens and writes 5 million in a month and the bill is $56.25 for Gemini 3.8 Flash High against $83.75 for Muse Spark 1.3 Max.

Cost per point of intelligence

Dividing the blended price by the intelligence index gives a rough cost per point: $0.049 for Gemini 3.8 Flash High and $0.055 for Muse Spark 1.3 Max, per million tokens. Gemini 3.8 Flash High delivers each index point for 11% less; whether Muse Spark 1.3 Max's extra 5.8 points are worth the premium depends on how often your tasks need them.
