Initially a closed-source company, Poolside's founders chose to open source their models. This was a philosophical choice to foster a world with 100 foundation model companies instead of five, driven by the fear that a handful of companies controlling all of intelligence would feel like a dystopian sci-fi novel.
Contrary to fears of a monopoly, the AI market is heading toward a diverse ecosystem. The proliferation of open-weight models and specialized tooling allows companies to build and control their own differentiated AI systems rather than simply renting intelligence token-by-token from a handful of large labs.
The current trend toward closed, proprietary AI systems is a misguided and ultimately ineffective strategy. Ideas and talent circulate regardless of corporate walls. True, defensible innovation is fostered by openness and the rapid exchange of research, not by secrecy.
The open vs. closed source debate is a matter of strategic control. As AI becomes as critical as electricity, enterprises and nations will use open source models to avoid dependency on a single vendor who could throttle or cut off their "intelligence supply," thereby ensuring operational and geopolitical sovereignty.
The choice between open and closed-source AI is not just technical but strategic. For startups, feeding proprietary data to a closed-source provider like OpenAI, which competes across many verticals, creates long-term risk. Open-source models offer "strategic autonomy" and prevent dependency on a potential future rival.
To avoid a future where a few companies control AI and hold society hostage, the underlying intelligence layer must be commoditized. This prevents "landlords" of proprietary models from extracting rent and ensures broader access and competition.
Contrary to past momentum, the most advanced AI startups are increasingly adopting and fine-tuning open-source models. This shift is driven by the need for cost-effective speed and deep customization as their workloads mature and scale.
Developers are adopting open-source models for stability, not just cost. The US government's unpredictable, ad-hoc decisions to pull advanced proprietary models from the market creates significant business risk. Once released, open-source models cannot be taken back, hedging against this regulatory uncertainty.
Instead of competing directly with AI giants like OpenAI and Anthropic, coding tool Warp is open-sourcing its platform. The strategy is to become a neutral environment where developers can run any coding agent they prefer. This shifts the battle from building the best agent to building the best ecosystem and distribution channel.
The idea that one company will achieve AGI and dominate is challenged by current trends. The proliferation of powerful, specialized open-source models from global players suggests a future where AI technology is diverse and dispersed, not hoarded by a single entity.
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.
