What it is

Msty is for anyone who regularly asks the same question to a local model and a cloud API, then compares outputs side by side. It bridges Ollama and OpenAI-compatible runtimes with Anthropic, OpenAI, and Gemini endpoints in a single chat window. You can run a 8B Q4_K_M model locally while a cloud model answers the same prompt in the adjacent panel. The UI is polished and the multi-model comparison view is genuinely unique. The catch: Msty is closed-source, and some advanced features require a paid plan. If you're evaluating whether a local model is good enough for your use case, this is the tool.
