Tigran Aivazian

Tigran Aivazian holds master's degrees in both computer science and theoretical physics from Yerevan State University.

He is currently developing Sigma AI, a first multi-model large language model (LLM) chat system.

Sigma AI is a Streamlit-based web application, available at [https://sigmaai.ai](https://sigmaai.ai), and written entirely in Python. The system enables users to engage in dialogue with multiple LLMs simultaneously, including Llama, Gemma, Mixtral, CodeLlama, gpt-4o, gpt-4o-mini, and gpt-3.5-turbo. It supports two basic modes of conversation: parallel (unbiased) and sequential (biased). In the parallel mode, the user's query (and any previous context) is sent to each activated model independently, so the models do not see each other's responses, providing unbiased, independent viewpoints. In the sequential mode, each subsequent model sees not only the query and context but also all previous models' responses, which may influence its own reply.

Tigran has also made significant contributions to the Linux kernel; he authored the BFS (Boot File System) and the Intel Microcode Update Driver, both of which have been part of the official Linux kernel source code since late 1990s.
