To survive against subsidized tools from model providers like OpenAI and Anthropic, AI applications must avoid a price war. Instead, the winning strategy is to focus on superior product experience and serve as a neutral orchestration layer that allows users to choose the best underlying model.

The true power of the AI application layer lies in orchestrating multiple, specialized foundation models. Users want a single interface (like Cursor for coding) that intelligently routes tasks to the best model (e.g., Gemini for front-end, Codex for back-end), creating value through aggregation and workflow integration.

Simply offering the latest model is no longer a competitive advantage. True value is created in the system built around the model—the system prompts, tools, and overall scaffolding. This 'harness' is what optimizes a model's performance for specific tasks and delivers a superior user experience.

Navan's CEO sees the debate over which LLM is best as unimportant because the infrastructure is becoming a commodity. The real value is created in the application layer. Navan's own agentic platform, Cognition, intelligently routes tasks to different models (OpenAI, Anthropic, Google) to get the best result for the job.

Instead of being a weakness, Cursor's reliance on multiple foundation models is a key strength. With 50% of developers switching model families daily, this approach allows Cursor to benefit from every improvement in any underlying model. This creates a compounding product flywheel, making the application layer an index of the entire AI ecosystem's progress.

Despite the power of large foundation models from OpenAI and Anthropic, specialized AI companies like Cursor are succeeding. This suggests the AI market is a rapidly expanding pie, not a winner-take-all environment, where "transcendent" companies with superior product execution can capture significant value.

The belief that a single, god-level foundation model would dominate has proven false. Horowitz points to successful AI applications like Cursor, which uses 13 different models. This shows that value lies in the complex orchestration and design at the application layer, not just in having the largest single model.

Like Kayak for flights, being a model aggregator provides superior value to users who want access to the best tool for a specific job. Big tech companies are restricted to their own models, creating an opportunity for startups to win by offering a 'single pane of glass' across all available models.

Instead of building its own models, Razer's strategy is to be model-agnostic. It selects different best-in-class LLMs for specific use cases (Grok for conversation, ChatGPT for reasoning) and focuses its R&D on the integration layer that provides context and persistence.
