Meta Releases Muse Spark 1.3 — A High-Performance Model

Meta has introduced Muse Spark 1.3, a model that showcases impressive performance at an affordable price.
Meta Releases Muse Spark 1.3
Meta's Muse Spark 1.3 model demonstrates performance on par with leading models while maintaining a nearly symbolic price.
This time, the release occurred without prior hype. Muse Spark 1.3 first appeared in Meta API and OpenCode, and only then did the company publish the test results.
On Terminal-Bench 2.1, the model scored 88.8, matching GPT-5.6 Sol. On DeepSWE, it achieved 75.4%, placing it among the strongest models for programming. The results in other tests are also quite impressive.
Muse Spark 1.3 is already available in Muse Code and via API.
Zuckerberg also hinted that the next major release will be Watermelon, and the open weights of Muse Spark are promised to be released soon.
