The generative AI revolution has created a fascinating divide in the tech world. Over the past three years, we've witnessed a dramatic shift from open-source innovation to increasingly closed APIs, sparking heated debates about the future of AI development. At the HubSpot for Startups annual AI Summit in San Francisco, a distinguished panel of AI leaders tackled this complex landscape, offering invaluable insights for startups navigating these choppy waters.
This session brought together some of the brightest minds in AI: Boris Power, Technical Staff Member at OpenAI; Alex Waibel, Research Fellow at Zoom and Professor at Carnegie Mellon; Percy Liang, Associate Professor at Stanford and Co-founder at Together.xyz; Brian Krausz, Technical Staff Member at Anthropic; and Vijay Narayanan, General Partner at Fellows Fund, who moderated the discussion.
The landscape isn't binary. Percy Liang kicked off the discussion by dismantling the common misconception that companies must choose between purely open or closed source approaches. The reality is far more nuanced.
Key insights on the spectrum approach:
Safety emerged as a critical differentiator between open and closed approaches. Brian Krausz from Anthropic highlighted why closed source models currently offer superior safety tools.
Safety isn't just content moderation—it's about preventing real-world harm as models become more powerful. GPT-4 already demonstrates superhuman capabilities in combining knowledge across domains, making safety considerations increasingly critical.
The panel identified two key safety categories:
The discussion revealed a pressing need for industry standards around AI model transparency. Percy Liang compared the current state to buying electronic parts—you get detailed spec sheets for hardware, but AI models lack similar documentation.
Essential transparency elements users should demand:
Alex Waibel raised a provocative point about the impossibility of universal morality in AI systems. Different regions have different values, and expecting companies to create universal moral frameworks is naive and potentially dangerous.
The solution? Trainable, modular morality systems that can be:
This approach would prevent AI companies from becoming "arbiters of truth"—a role that has proven problematic in social media.
Boris Power emphasized how closed source APIs have democratized AI development, enabling creative individuals without machine learning backgrounds to build incredible applications quickly. This has given birth to the "full-stack engineer as single-person company" phenomenon.
However, the panel noted that API access is orthogonal to the open/closed debate—you can have APIs for both open and closed source models.
The panelists identified several critical research challenges that need addressing:
Technical Challenges:
Governance Challenges:
Percy Liang concluded with a thought-provoking analogy to Wikipedia—a decentralized knowledge system that shouldn't work but does. He challenged the current paradigm of centralized AI development, suggesting we're in a "local optimum" that might benefit from complete reimagining.
Key questions for the future:
For founders navigating this landscape, the message is clear: build with flexibility in mind. The AI ecosystem is moving incredibly fast, and what's optimal today may not be tomorrow. Focus on:
The open vs. closed debate isn't going away, but it's becoming increasingly clear that the future lies not in choosing sides, but in building systems flexible enough to leverage the best of both worlds.
