OpenAI embraces the 'platform paradox' by selling API access to startups that compete directly with its own apps like ChatGPT. The strategy is to foster a broad ecosystem, believing that enabling competitors is necessary to avoid losing the platform race entirely.

In an AI-driven ecosystem, data and content need to be fluidly accessible to various systems and agents. Any SaaS platform that feels like a "walled garden," locking content away, will be rejected by power users. The winning platforms will prioritize open, interoperable access to user data.

The idea of a truly "open web" was a brief historical moment. Powerful, proprietary "organizing layers" like search engines and app stores inevitably emerge to centralize ecosystems and capture value. Today's AI chatbots are simply the newest form of these organizing layers.

OpenAI has a strategic conflict: its public narrative aligns with Apple's model of selling a high-value tool directly to users. However, its internal metrics and push for engagement suggest a pivot towards Meta's attention-based model to justify its massive valuation and compute costs.

Unlike sticky cloud infrastructure (AWS, GCP), LLMs are easily interchangeable via APIs, leading to customer "promiscuity." This commoditizes the model layer and forces providers like OpenAI to build defensible moats at the application layer (e.g., ChatGPT) where they can own the end user.

Startups are becoming wary of building on OpenAI's platform due to the significant risk of OpenAI launching competing applications (e.g., Sora for video), rendering their products obsolete. This "platform risk" is pushing developers toward neutral providers like Anthropic or open-source models to protect their businesses.

Beyond its technical capabilities, OpenAI's app ecosystem within ChatGPT functions as a new distribution platform. For founders, this creates a strategic opportunity to build apps that serve as an interface layer to their product, opening a novel and potentially powerful channel for user acquisition and growth.

Despite its massive user base, OpenAI's position is precarious. It lacks true network effects, strong feature lock-in, and control over its cost base since it relies on Microsoft's infrastructure. Its long-term defensibility depends on rapidly building product ecosystems and its own infrastructure advantages.

Similar to how mobile gave rise to the App Store, AI platforms like OpenAI and Perplexity will create their own ecosystems for discovering and using services. The next wave of winning startups will be those built to distribute through these new agent-based channels, while incumbents may be slow to adapt.
