Frequently asked questions
How much does Muse Spark 1.3 cost?
We do not have a supplied price for Muse Spark 1.3, so we show none rather than estimate one. Check Meta's pricing page. When a price is supplied it appears here with the date.
How large is the Muse Spark 1.3 context window?
No context window was supplied for Muse Spark 1.3, so we do not state one.
Is Muse Spark 1.3 an open-weights model?
No. It is recorded as a closed model that you reach through Meta's API or products.
Is Muse Spark 1.3 better than other models?
We cannot say. No quality benchmark for it is published on this site, and the Model Finder orders results by cost, not quality. Use the finder to shortlist models, then test them on your own prompts.
