Arthur Mensch argues that the core knowledge for training advanced AI models is limited and circulates quickly among top labs. This diffusion of knowledge prevents any single company from creating a sustainable IP-based lead, which is accelerating performance convergence and commoditization across the industry.

While techniques like model distillation can reduce costs for near-frontier AI capabilities, this hasn't dampened demand for the absolute best models. The market shows very little desire for the third-best model, but exceptional demand for the top-performing one for any given task, demonstrating a winner-take-all dynamic.

Leading AI models are becoming increasingly similar in capability. This rapid convergence suggests the underlying technology is becoming a commodity, and competitive advantage will likely shift to user interface, distribution, and specific applications rather than the core model itself.

Top-tier coding models from Google, OpenAI, and Anthropic are functionally equivalent and similarly priced. This commoditization means the real competition is not on model performance, but on building a sticky product ecosystem (like Claude Code) that creates user lock-in through a familiar workflow and environment.

The novelty of new AI model capabilities is wearing off for consumers. The next competitive frontier is not about marginal gains in model performance but about creating superior products. The consensus is that current models are "good enough" for most applications, making product differentiation key.

The current oligopolistic 'Cournot' state of AI labs will eventually shift to 'Bertrand' competition, where labs compete more on price. This happens once the frontier commoditizes and models become 'good enough,' leading to a market structure similar to today's cloud providers like AWS and GCP.

If AI makes intelligence cheap and universally available, its economic value may collapse. This theory suggests that selling raw AI models could become a low-margin, utility-like business. Profitability will depend on building moats through specialized applications or regulatory capture, not on selling base intelligence.

Unlike traditional SaaS where high switching costs prevent price wars, the AI market faces a unique threat. The portability of prompts and reliance on interchangeable models could enable rapid commoditization. A price war could be "terrifying" and "brutal" for the entire ecosystem, posing a significant downside risk.

While the most powerful AI will reside in large "god models" (like supercomputers), the majority of the market volume will come from smaller, specialized models. These will cascade down in size and cost, eventually being embedded in every device, much like microchips proliferated from mainframes.
