Open vs. Closed Source AI: Expert Insights on Navigating the Generative AI Landscape

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 False Dichotomy: It's Not Just Open vs. Closed

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:

  • Models are interoperable: Most AI models behave similarly enough that switching costs can remain relatively low
  • Performance characteristics vary: Each model has different cost structures and capabilities that change rapidly
  • Benchmarking is crucial: Rigorous testing helps companies make intelligent switching decisions as needs evolve
  • Adaptation happens fast: The open-source ecosystem enables rapid iteration—within 24 hours of releasing the RedPajama dataset, someone was already training models on it

The Safety Debate: Where Closed Source Still Leads

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:

  • Accidents: Well-intentioned users making careless mistakes (where open source community tools can help)
  • Misuse: Intentional harmful applications (where closed systems provide better control mechanisms)

The Transparency Challenge: What Users Should Demand

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:

  • Performance specifications: Clear descriptions of what models can and cannot do
  • Benchmarking data: Comprehensive performance characteristics across different domains
  • Training data transparency: Information about data sources, potential biases, and ethical considerations
  • Recourse mechanisms: Clear processes for feedback and model improvement
  • Labor practices: Documentation of who produced datasets and under what conditions

The Localization Imperative: One Size Doesn't Fit All

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:

  • Customized for local values and regulations
  • Interactive in handling sensitive topics
  • Transparent in their decision-making processes
  • Adaptable to different cultural contexts

This approach would prevent AI companies from becoming "arbiters of truth"—a role that has proven problematic in social media.

The API Advantage: Democratizing AI Development

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.

Future Challenges: The Road Ahead

The panelists identified several critical research challenges that need addressing:

Technical Challenges:

  • Trainable moral guidelines: Automated, localized ethical frameworks
  • Watermarking and provenance: Knowing when content is AI-generated
  • Confidence metrics: Understanding when models are uncertain
  • Federated learning: Combining public and private model components

Governance Challenges:

  • International coordination: Preventing a "race to the bottom" on safety
  • Regulatory frameworks: Establishing reasonable risk thresholds
  • Value alignment: Determining whose values should guide AI development

The Wikipedia Model: Reimagining AI Development

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:

  • How do we want this technology to develop in society?
  • Who should contribute to AI development, and how?
  • How should the value and profits be shared?
  • How do we maintain safety in decentralized systems?

Bottom Line for Startups

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:

  • Interoperability: Choose solutions that allow easy switching between models
  • Rigorous benchmarking: Test thoroughly before committing to any single approach
  • Safety considerations: Understand the trade-offs between open and closed systems for your use case
  • Future-proofing: Build architectures that can adapt as the landscape evolves

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.
