AI Model Progress vs. Investment Shows Sublinear Efficiency

@martin_casado· August 1, 2026 View original

Key takeaways

  • AI model capabilities are advancing rapidly.
  • Efficiency of AI development may decrease with scale and increased investment.
  • Sublinear returns on investment in large AI labs are a potential concern.
  • The "take off" narrative for AI efficiency might be oversimplified.

Summary

The pace of AI model capabilities is accelerating, but when measured against the financial investment, the efficiency appears to be sublinear, suggesting organizations become less efficient at scale.

The rapid advancement in AI model capabilities and releases is evident, yet a closer look reveals a nuanced trend. When the progress is weighed against the substantial financial investments made by labs, the efficiency gains appear to be less than proportional. This suggests that as AI organizations grow, their ability to convert capital into new capabilities might diminish. The overall picture indicates a complex relationship between funding and innovation, rather than a straightforward exponential "take off" in efficiency.

Why it matters

Professionals should understand that increasing investment in AI research does not necessarily yield proportionally faster or better results, impacting strategic resource allocation and R&D planning.

How to implement this in your domain

  1. 1Evaluate current AI R&D spending against tangible output and innovation metrics.
  2. 2Investigate potential bottlenecks or inefficiencies in large-scale AI development teams.
  3. 3Consider diversifying AI investment strategies beyond just increasing capital into existing large labs.
  4. 4Benchmark internal AI development efficiency against industry peers, if data is available.

"It appears model capabilities / releases are accelerating. But if you divide by the money going into the labs, it looks sublinear. Clearly orgs get less efficient at scale. But the picture is not obvious “take off”."
