Please give it a try and let us know ;) judging by the benchmark scores I would not expect too much of a difference.

Main difference seems to be that this one is cheaper/easier to host.

I used spark 1.3 extensively in prime-agent (a pi derivative) and I thought it was great.

Speaks nicely, great at driving linux. Not frontier-level coding, but comparable to luna, deepseek. It was amazing for the price.

Artifical Analysis says is this comparable to DeepSeek 4.1.

But weaker than Muse Spark 1.3: https://i.imgur.com/8ST1rRY.png

    Muse Spark 1.3 (Xhigh)     45
    Muse Spark Open (Xhigh)    39
    DeepSeek V4.1 Flash (Max)  39
