September 16, 2026 · correction of this site's reading
Correction of our own reading, not a price change by Meta. From September 11 to September 16, 2026 this site showed Muse Spark 1.3 and Muse Spark 1.2 as 'no published price', because Meta's model pages serve their 'Models and pricing' table only to a browser, and the HTTP client this site verifies with received a JavaScript shell with no pricing text. Read by hand in a browser on September 16, 2026, each page lists two SKUs per model: 'Not used to improve our products' at $1.25 input, $0.15 cached input and $4.25 output per million tokens, and a 'contributor' SKU, 'Used to improve our products', at $0.10 / $0.002 / $0.20, conditional on letting Meta use the traffic to improve its products. The rows now carry the first as the list price, with the contributor price quoted in their notes; Meta changed nothing. Muse Spark 1.1's own model page, read the same day in a browser, carries a benchmark table and no pricing table, and neither of the other two tables lists it, so that row still shows no published price.

Read by hand in a browser on 2026-09-16 from the 'Models and pricing' table of the model page, row 'muse-spark-1.3 | Not used to improve our products. | 1M | $1.25 | $0.15 | $4.25' (input, cached input, output per Mtok). The same table lists a second SKU, 'muse-spark-1.3-contributor | Used to improve our products. | 1M | $0.10 | $0.002 | $0.20', conditional on letting Meta use the traffic to improve its products; it is not the list price and is not shown. The page serves that table only to a browser: a plain HTTP client gets a JavaScript shell with no pricing text, which is why this row said 'no published price' from 2026-09-11 to 2026-09-16 (a reading error of this site, not a change by Meta).
