## Summary

Meta announced an open‑weight multimodal MoE model called Muse Spark Open on October 15th. The model has 816 billion parameters and can generate text from text, images, audio, and video while specializing in agentic coding, where it writes and executes code autonomously.

The article advises users to shift toward "agentic coding" by clearly stating desired outcomes, delegating low‑risk tasks such as data‑analysis scripts, and leveraging multimodal inputs like handwritten drafts and audio explanations. Early adopters report that tasks that previously took days can now be completed in a few hours, suggesting a potential change in how businesses automate routine work.

## Key points

- Meta announced Muse Spark Open, an open‑weight multimodal MoE model with 816 billion parameters.
- The model generates text from text, images, audio, and video and is built for agentic coding.
- Meta recommends using the model for small delegated tasks and multimodal inputs like handwritten drafts.

## Why it matters

An open‑weight 816 billion‑parameter multimodal model lets developers customize autonomous coding and multimodal workflows, potentially reshaping automation across industries.
