Reasoning and overall scores

On the intelligence index, Muse Spark 1.3 Max scores 36.6 against 24.9 for Muse Spark Open. That is a wide gap for an aggregate score.

Among 109 active scored models, Muse Spark 1.3 Max sits 36th and Muse Spark Open 68th.

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

Which is newer

The release dates are September 2, 2026 for Muse Spark 1.3 Max and October 15, 2026 for Muse Spark Open, 43 days apart. That is close enough to count them as the same generation.

What they cost

The list prices are $1.25 in and $4.25 out for Muse Spark 1.3 Max, and $1.25 in and $4.25 out for Muse Spark Open, per million tokens. The rates are identical, so price will not separate them.

Is the price in proportion?

A blunt value measure, blended price over intelligence score, puts Muse Spark 1.3 Max at $0.055 and Muse Spark Open at $0.080 per point. Muse Spark 1.3 Max scores higher and costs less per point, so on price per point there is nothing to trade off.

Speed and latency

Muse Spark 1.3 Max generates about 140 tokens per second and Muse Spark Open about 207 tokens per second. On long outputs, that is a real advantage for Muse Spark Open. Time to first token is 36 seconds for Muse Spark 1.3 Max and 0.94 seconds for Muse Spark Open. In an interactive app, Muse Spark Open will feel noticeably more responsive. Waits that long are felt on every chat-style request, though they matter less for batch jobs.

For a 2,000-token response, first token plus generation comes to roughly 50 seconds on Muse Spark 1.3 Max and 11 seconds on Muse Spark Open.
