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

gpu.nz is a service that provides cloud-based GPU rentals tailored for developers, machine-learning professionals, researchers, and creators who require immediate computing power for tasks such as AI inference, model training, image and video creation, and rendering. Users can assess various GPU options based on model, memory capacity, geographical location, and hourly pricing, and subsequently initiate servers with pre-established configurations including tools like ComfyUI, Stable Diffusion Forge, Ollama with Open WebUI, vLLM, PyTorch, and Jupyter, or opt for a personalized Docker image. GPU usage is charged by the minute from a preloaded balance, with a fixed rate established at the moment a server is activated; halting the server stops the GPU fees while disk storage continues to incur charges. Additionally, the platform offers a web console, a REST API, a command-line interface, and a hosted Model Context Protocol server to facilitate both manual and automated processes for searching, launching, and managing servers. This comprehensive system ensures that users have the flexibility and tools necessary to optimize their computing tasks effectively.

Pricing Details

$0.067/hour
GPU rental is billed per minute from an account balance at the hourly rate for the selected server; the rate is fixed when the server starts. A $2 minimum top-up applies. Stopping a server ends GPU charges, but disk storage remains billable. Data transfer is billed per gigabyte. Prices and availability vary by offer.
