Sigma browser runs local LLM Eclipse

Sigma is a privacy-forward Chromium browser that ships with a local LLM called Eclipse, running on hardware via llama.cpp with no account or API key needed. AI Chat, Search, and Agent are the three ways to interact. Agent tasks require an API key from providers like Anthropic or OpenAI. The browser includes a built-in VPN, ad blocker, and open-source codebase.
