On financial analyst benchmarks, top models from Anthropic, Google, and OpenAI are now almost indistinguishable in capability. This convergence suggests the frontier is commoditizing, questioning the return on investment for massive training runs and shifting value up the application stack.

Creating frontier AI models is incredibly expensive, yet their value depreciates rapidly as they are quickly copied or replicated by lower-cost open-source alternatives. This forces model providers to evolve into more defensible application companies to survive.

Contrary to the popular narrative that open-source AI will quickly commoditize the market, there is evidence that the frontier is accelerating faster than the open-source community can keep up. This potential divergence challenges the 'good enough' argument and suggests that proprietary models may maintain a significant, defensible lead for longer than expected.

While US firms lead in cutting-edge AI, the impressive quality of open-source models from China is compressing the market. As these free models improve, more tasks become "good enough" for open source, creating significant pricing pressure on premium, closed-source foundation models from companies like OpenAI and Google.

Recent tests on NVIDIA B200 GPUs show that open-source models like China's GLM 5.2 can match or exceed the performance of proprietary models for tasks like coding. This performance threatens the moats of large, closed AI labs.

Fears of a single AI company achieving runaway dominance are proving unfounded, as the number of frontier models has tripled in a year. Newcomers can use techniques like synthetic data generation to effectively "drink the milkshake" of incumbents, reverse-engineering their intelligence at lower costs.

In the vacuum left by banned US frontier models, Chinese labs are releasing powerful and cost-effective open-source alternatives like ZAI's GLM 5.2. These models are proving competitive on valuable, complex tasks like UI design and coding, but at a fraction of the cost.

While open-source models are improving, frontier models will remain valuable. There is always demand for the most capable model to unlock novel applications, like advanced scientific research. Frontier labs also possess scale advantages in compute access and cost efficiency that are hard to replicate.

The rapid progress of open-source models is evidence that data is the primary driver of AI capability, not proprietary architectures or training tricks. Data can be easily distilled from public APIs, allowing competitors to quickly close the gap with frontier models, which would be impossible if secret architectural tricks were the main advantage.
