# Meta's Muse Spark Open is now available in Buildful

By [Sandeep Panda](https://buildful.ai/authors/sandeep) Oct 16, 2026 

Meta's Muse Spark Open is now in Buildful's model picker on Pro and Team. Pick the open-weight model for a coding task, and it opens a tested pull request on your GitHub repo like any other model.

More models came into the picker the same day: Muse Wonder 1.0, Kimi K3, Qwen 3.8 Max, GLM 5.3, Gemini Argon, Gemini 3.8 Flash and Claude Haiku 5.5\. Each one shows its provider's logo. Models you pick yourself don't use your plan's tasks: you pay for them from prepaid credit. See [pricing](https://buildful.ai/pricing) for how credit works, and [open-weight models](https://buildful.ai/open-weight-models) for how Buildful uses them.

## Archive finished tasks

You can archive a task once it has finished. Open the menu on its row in the task list and choose Archive. The task leaves your list but keeps its conversation and pull requests, and you'll find it under Archived in the sidebar. Choose Unarchive to bring it back, or send it a message.
