Description
Muse Spark Open is an open-weight foundation model developed by Meta to support multimodal reasoning, autonomous agents, and complex software development tasks. The model features 816 billion total parameters with approximately 42 billion active parameters and a context window supporting up to one million tokens. Its architecture is designed to process multimodal information while maintaining context across lengthy workflows, extensive codebases, and multistep assignments. Muse Spark Open provides capabilities for software engineering, code generation, debugging, application development, and automated testing. Its agentic functionality supports external tool interactions, task planning, computer-based workflows, and execution of complex objectives over extended sessions. The model can run locally using two Apple M5 Ultra Mac Studio systems with the MLX framework, enabling organizations to process information without relying on hosted inference services. Developers can deploy the model through SGLang, vLLM, TensorRT-LLM, Hugging Face Transformers, llama.cpp, and other supported inference engines. Customization is supported through PyTorch and TorchTitan, allowing organizations to adapt the model to specialized applications and workflows. Muse Spark Open is distributed under the Muse Model License and is available through Hugging Face, major cloud model repositories, and hosted API providers including Together AI, Fireworks AI, and OpenRouter.
Description
Polyant is a collaborative open-source platform designed to assemble teams of specialized AI agents that assist company personnel by managing tasks such as sales briefs, customer triage, document extraction, and compliance reporting.
With its modular and self-hosted framework, teams have the flexibility to select their preferred model providers, including open-weight models, and can utilize their own infrastructure, ensuring they are never tied to a single vendor. From the outset, the platform includes governance and auditing tools tailored to meet EU AI Act requirements, with all agent decisions meticulously recorded in a compliance-friendly audit registry accessible to compliance teams. Organizations maintain comprehensive control over data residency options, allowing deployment on-premises, within their own cloud, or utilizing EU infrastructure managed by Exelab. Furthermore, the deployment of agents can occur in mere days rather than the typical months, all while retaining self-hosting capabilities and adhering to governance standards. This solution is particularly tailored for mid-to-large European enterprises operating in regulated industries such as banking, insurance, and healthcare, where relying solely on a hosted API is not a viable option, ensuring that companies can effectively manage their AI integration in a compliant manner.
