Altera, an independent research lab founded by Dr. Robert Yang after leaving MIT, is pioneering the development of 'digital humans'—AI agents designed to collaborate with people in meaningful, human-like ways. While not part of OpenAI, Altera's agents are powered by OpenAI's GPT-4o. These agents go beyond assistance to interact, collaborate, and even experience emotions. They can perform tasks autonomously for up to four hours at a time, a substantial increase compared to other AI models on the market. From playing Minecraft with users to tackling long-term autonomy challenges, Altera aims to redefine human-AI collaboration.
