How open model ecosystems compound
Summary
The development of leading frontier AI models incurs approximately 80% of its compute costs in research and development (R&D), rather than in the final end-to-end training of the largest model, according to recent research from Ai2 (documenting Olmo 3) and Epoch AI. This R&D-heavy cost structure provides a significant advantage to ecosystems like China, where leading players openly share knowledge and de-risk ideas, effectively reducing redundant R&D compute and infrastructure efforts across labs. Unlike traditional open-source software (OSS) where user feedback reduces costs, open AI models primarily reduce future development and deployment costs for the creator and the broader ecosystem, rather than offering immediate plug-and-play cost reductions for individual users. The current trend of companies forking open-source tools into internal-only versions hinders the full realization of these cost benefits, suggesting a need for a shared, open model consortium to sustain competitive development at the frontier scale.
Key takeaway
For research scientists developing frontier AI models, understanding that R&D constitutes the majority of compute costs is critical. You should evaluate the benefits of participating in or forming open model consortia to share knowledge and infrastructure, as this collaborative approach can significantly reduce redundant R&D efforts and enhance long-term financial viability compared to isolated, proprietary development paths. This strategy is essential for competing effectively at the future frontier scale.
Key insights
Most AI model compute costs stem from R&D, favoring open ecosystems that share knowledge.
Principles
- R&D accounts for ~80% of frontier model compute costs.
- Open knowledge sharing reduces redundant R&D compute.
- Open models reduce future costs for creators and ecosystem.
Method
Chinese labs reduce R&D costs by sharing thorough technical reports and knowledge, de-risking ideas for peer companies and avoiding duplicated resource investment.
In practice
- Consider R&D compute as the primary cost driver.
- Explore open model consortia for shared resource efficiency.
