Does Msty AI Work Completely Offline?

Yes. Once a local model is downloaded through Local AI, Llama.cpp, or MLX, Msty Studio runs inference entirely on-device with no internet connection required. Only optional features like Real-Time Data, cloud providers, and model downloads need network access.

What Is The Difference Between Msty Studio, Go, And Nexus?

Studio is the chat and knowledge workspace, Go handles bounded multi-step task agents across desktop and mobile with reviewable execution, and Nexus acts as a local gateway managing runtimes, provider credentials, routes, and app tokens. Each runs standalone or connected.

Which Model Providers Does Msty AI Support?

Msty connects to OpenAI, Anthropic, Google, xAI, Groq, OpenRouter, MiniMax, Z.ai, Azure OpenAI, and AWS Bedrock, plus any OpenAI-compatible endpoint. Locally it supports Ollama, Llama.cpp, MLX, LM Studio, and direct GGUF or Safetensors imports.

How Do Knowledge Stacks Handle Large Document Sets?

Knowledge Stacks vectorize files, folders, webpages, conversations, and projects with configurable embedding models, folder watch sync, pause-resume compose, and re-ranking. Dynamic Mode lets tools search metadata first and pull full files only on demand.

Can Msty Studio Replace A Self-Hosted Chat UI For Teams?

For many organizations, yes. Team deployments add SSO, role-based access, shared Knowledge Stacks and Toolbox artifacts, audit logs, and customer-controlled storage without maintaining your own inference stack or web server infrastructure.
