Diogo Antunes
AI Scientist & Entrepreneur
Specialized in Machine Learning and Deep Learning with expertise in transformer architectures, reinforcement learning, and enterprise AI systems. Building the future of intelligent software at the intersection of research and practical applications.

Pioneering Value-Driven AI Systems
At 23, I'm redesigning artificial intelligence to be autonomous, safe, and value-aligned. Through Vaisys Inc., we're building the next generation of AI that moves beyond conversation to meaningful action—always with humans in control.
The Value-Driven Approach
As an AI Scientist and entrepreneur, I believe artificial intelligence should serve humanity with clear values: transparency, collaboration, and responsible innovation. My work focuses on moving beyond the limitations of current language models to create systems that can autonomously execute complex tasks while maintaining human oversight.
Through deep expertise in transformer architectures, reinforcement learning, and advanced optimization techniques, I'm building AI systems that understand not just what to do, but why it matters. This perspective drives innovation that creates impactful, trustworthy technology.
My vision extends beyond technical excellence—I'm an entrepreneur who sees AI as a tool for positive societal transformation. Every system I design prioritizes safety, value-alignment, and the principle that AI should amplify human capability, not replace human judgment.
