Meta’s Muse Spark Open, a high‑capacity US open‑weight model for agentic software engineering, is now live on Together AI as a Day 0 launch partner. The model supports a 1‑million‑token context window to keep entire codebases—including legacy and complex dependencies—in a single prompt, offers long‑horizon planning, tool calling, and self‑correction, and can consume multimodal inputs (text, image, audio, video) while browsing the web. Early access customers such as Factory and Ollama have deployed it immediately post‑launch and report improved first‑attempt accuracy and efficient developer workflows.
