Which one should you be using?
Muse Spark 1.3 is the newest released model in the family, out on 2026-09-02. Newer is not automatically better for your job, but it is usually the one the lab is optimising, and on this table it is rarely the most expensive.
Why there are so many numbers
A point release is a new model, not a patch. Meta ships a new one under the same family name when the training or the tuning changes, and the old one usually keeps working at its old price until it's deprecated.
That's why two models in this table can hold the same amount of text and cost different amounts. You're picking a specific model, not a family, and the API name in each model's page is what actually goes in your code.
What each one is for
- Muse Spark 1.3Meta's frontier model ships under Muse now, not Llama. A contributor tier drops the input price to ten cents a million if you qualify.
- Muse Spark 1.1The first Muse Spark and the launch of Meta's own model API. It went out as a public preview and is priced the same as the two that followed.
- Muse Spark 1.2Same price and window as 1.3. Meta never posted a launch date for it, only an evaluation follow-up in August, so we've left the date blank.
