Muse Spark 1.3
Meta's hosted model for long-horizon coding and agentic work, sold through the Meta Model API (public preview). A Contributor tier at $0.10 / $0.20 is far cheaper but lets Meta use your data to improve its products.
Model ID: muse-spark-1.3
What that means
A worked example
Per-token pricing is hard to feel. Take a moderately chatty production workload: 100 calls a day, roughly 10,000 tokens in and 2,000 out each time. On Muse Spark 1.3 that comes to about:
$63 / month
Before caching, batching or volume discounts, all of which move this number a long way. Illustrative only.
