About

Izuran Pro is a native AI assistant for Apple Silicon Macs that runs open-weight models on the user’s Mac or on a model server within the user’s network. It can work with local files and folders, calendars, reminders, contacts, notes, mail and other enabled Mac apps; organize work into projects; plan and schedule tasks; and show proposed changes for review. The built-in MLX engine supports downloadable models such as Qwen and Gemma, while users can add local model servers and their own MCP tools. Optional connections include Gmail, Signal, Apple services, Philips Hue, web search through xAI, and payments through Link. A paired iPhone app supports conversations and approvals, while voice and Apple Watch capabilities remain in testing. Izuran Pro is currently distributed by invitation in private beta. AIC also offers private-network server deployments for offices and teams.

About

Muse Spark Open is an open-weight, natively multimodal language model for developers and organizations building AI applications, coding systems, and agentic workflows. The released model has 816 billion total parameters, 42 billion active parameters, and a 1-million-token context window. Teams can download the model weights, run inference through supported engines such as vLLM, SGLang, TensorRT-LLM, Hugging Face Transformers, Apple MLX, llama.cpp, or Unsloth, and customize the model using PyTorch. It supports long-context reasoning, software engineering, coding, tool use, and multimodal inputs. Deployment options include cloud inference through listed API providers or self-hosting on compatible GPU systems; Meta documents a desktop setup using two Apple M5 Ultra Mac Studio computers. The model is released under the Muse Model License with limited commercial terms.

Pros & Cons from Real Users

Pros

  • Meta finally opened up a genuinely frontier-level Muse model. The 1M-token context window and 42B active parameters make it strong enough for large repos, long agent sessions, multimodal work, and complex coding without feeling like a stripped-down open model. The local deployment story is also a huge deal. Being able to run something this capable on two M5 Ultra Mac Studios is impressive, especially for teams that want more control over data, infrastructure, and customization. I also like how much of the stack is open around it. Muse Spark Open works with MLX, vLLM, SGLang, TensorRT-LLM, Transformers, llama.cpp, and Unsloth, and Meta is making the weights available through Hugging Face, SageMaker, Google Cloud Model Garden, and Microsoft Foundry.

Cons

  • Even though it is technically desktop-capable, needing two M5 Ultra Mac Studios for the full local experience is still a serious setup, so most developers will probably use hosted inference instead.
