Despite fears that cheaper, open-source models would commoditize the market, the opposite is happening. While token usage for cheaper models is rising, the actual share of economic value (wallet share) is increasingly flowing to expensive frontier labs like Anthropic and OpenAI.

China is pursuing a low-cost, open-source AI model, similar to Android's market strategy. This contrasts with the US's expensive, high-performance "iPhone" approach. This accessibility and cost-effectiveness could allow Chinese AI to dominate the global market, especially in developing nations.

Anthropic is positioning itself as the "Apple" of AI: tasteful, opinionated, and focused on prosumer/enterprise users. In contrast, OpenAI is the "Microsoft": populist and broadly appealing, creating a familiar competitive dynamic that suggests future product and marketing strategies.

Despite powerful open-source AI models, companies like Anthropic post record revenue. This indicates the total addressable market (TAM) is dramatically larger than anticipated, supporting both paid and open-source ecosystems simultaneously rather than one cannibalizing the other.

The AI model market has two clear segments: expensive, high-IQ frontier models for critical tasks like cybersecurity, and small, cheap, fast models for high-volume, simple tasks. Mid-tier models are struggling to find a clear product-market fit, as users gravitate to either extreme.

The market for AI models is bifurcating. Users either pay a premium for top-tier frontier models for high-stakes tasks like cybersecurity or use extremely cheap, small models for high-volume, simple tasks. Mid-tier models struggle to find a viable use case, getting squeezed from both ends.

Open and closed source AI models will coexist by serving different parts of the market. Companies with core AI needs and large budgets will "build" on open source for control and customization. Most others will "buy" closed-source APIs for convenience, mirroring the established build-vs-buy dynamic for other technologies.

Analyst Gavin Baker argues a few dominant AI labs create a monopsony (a dominant buyer) for compute, suppressing margins for everyone else. The rise of competitive open-source models decentralizes this power, shifting value back to other layers of the AI stack, from chips to software and cloud providers.

The AI model landscape will likely bifurcate like computer operating systems. Closed-source models (OpenAI, Anthropic) will dominate user-facing applications (like Windows/macOS), while open-source models will become the Linux of AI, powering backend enterprise infrastructure and custom applications.
