Speaker

Sam Altman, CEO of OpenAI, discusses the company’s origins, AI products and infrastructure, and startup strategy with a Y Combinator host.

Choosing an ambitious mission

Altman says starting OpenAI was uncertain: in 2015, AGI seemed like a distant goal, and DeepMind appeared far ahead. The early team had eight people, no product or revenue, and was trying to produce useful research. He says a distinctive mission helped attract researchers who believed in the goal.

Building products around new model capabilities

Altman says there is a large gap between what reasoning models can do and the products built to use them. He expects model costs to fall and describes an upcoming open-source model that could run powerful systems locally. He sees ChatGPT memory, data connections, and persistent background assistance as steps toward a service that can proactively help users.

Agents, interfaces, and hardware

Altman describes agents such as Codex and Deep Research as junior employees that can handle computer-based tasks for a few hours. He imagines AI interfaces that can act with less interruption, alongside new devices and eventually robots that do useful physical work. He also connects AI and robotics to a possible revival of domestic manufacturing.

Finding room for startups

Altman advises founders not to build a copy of ChatGPT’s core assistant, but to explore the much wider range of problems AI can address. He says companies often earn time to develop defensibility by doing something distinctive before competitors converge. He also argues that faster, cheaper iteration gives startups an advantage when technology changes an industry’s pace.

Scaling capability and scientific discovery

Altman says AI could help individuals and small teams accomplish more by reducing coordination costs. He is especially interested in AI for science, which he sees as a path to faster discoveries and long-term improvements in people’s lives. He links that ambition to energy, which he describes as a fundamental constraint on expanding AI.

Takeaways

  • Choose a market where success could become significant, then focus on getting the first thing to work.
  • Look for product opportunities created by current model capabilities, even as models continue to improve.
  • Build around a distinct problem instead of copying the most popular AI startup idea.
  • Hire for demonstrated work, learning speed, drive, and teamwork rather than prestigious credentials alone.
  • Develop conviction and resilience for work that may stay difficult and out of fashion for a long time.
