from my first look + experience at using astra + muse spark now.

it's crazy how muse spark 1.3 max is fable / gpt-6 astra high level intelligence at the same price of gpt 5.6 sol high (ish)

comparing all RELATIVE models, spark 1.3 max is the best model per dollar

for pure coding, muse spark 1.3 is better value.
