Summary written from the original first-party source — the link to it is at the end of this post.
Meta released Muse Spark 1.3 on September 2, an update to its open-weight image generation line, alongside a contributor-tier variant. It’s an iteration rather than a new flagship — a steady cadence of improvements on the Spark family that Meta has been shipping through 2026.
Who this is for
If you build on the Muse family — self-hosting, fine-tuning, or running it through applications like ComfyUI — 1.3 is the version to pick up, since the Spark line keeps its permissively licensed open weights as the point of differentiation against closed image models. Nothing here changes the competitive picture dramatically, but for teams already on Muse it’s a low-friction jump with the usual iteration-level quality gains. Details and model weights are on Meta’s AI blog.
