Bertagnoli argued that the current dominant paradigm of homogeneous intelligence, characterized by scaling single models on identical hardware, is giving way to a more sophisticated approach: heterogeneous intelligence.

These laws suggested that more data and parameters directly correlated with improved model performance. However, Bertagnoli highlighted that real-world problems are inherently complex, often multi-step, and open-ended. Solving them effectively requires not just larger models, but a more nuanced approach that can adapt to diverse challenges. He explained that the paradigm is already shifting, evidenced by the emergence of concepts like "Mixture of Experts" and multi-agent systems, where different models collaborate. This movement towards heterogeneity is further supported by new generations of silicon designed to unlock new performance levels for specialized tasks. However, Bertagnoli noted a critical gap: the lack of infrastructure to unify these diverse components. ## The Principle of Maximum Heterogeneity Callosum, Bertagnoli's company, has formalized the theoretical foundation for this new paradigm, which they term "Maximum Heterogeneity." This principle suggests that by strategically distributing computational workloads across a diverse set of models and hardware, AI systems can achieve optimal performance. Bertagnoli illustrated this with a conceptual cube, where the axes represent different dimensions of heterogeneity, from model diversity to hardware specialization. He presented research demonstrating that across various domains, including AI, neuroscience, economics, and ecology, heterogeneous resources can indeed push the "Pareto front" of what systems can achieve. This means that by leveraging diversity, systems can simultaneously improve performance and reduce costs, a feat difficult to accomplish with homogeneous approaches. Bertagnoli elaborated on the practical implications, explaining that while homogeneous systems might scale by using many identical components, heterogeneous systems achieve greater efficiency by using the right tool for the right job. This involves mapping different sub-tasks to specialized models and hardware, thereby saving costs and increasing speed. ## Heterogeneous Intelligence in Practice The presentation showcased practical examples of this heterogeneous approach. In the realm of workflows, Bertagnoli highlighted "automated workflow decomposition" and "heterogeneous recursion," where complex tasks are broken down and managed by specialized agents. These agents, he explained, can be multimodal, incorporating various types of data and reasoning, and can be orchestrated to interact with each other. A key aspect discussed was the concept of "heterogeneous hardware orchestration." This involves deploying different models onto specialized hardware, such as CPUs, GPUs, and custom ASICs, optimizing for the specific computational demands of each task. Bertagnoli pointed to the fact that while homogeneous scaling of LLMs on single chips was the norm, the move towards heterogeneous systems is now enabling more efficient inference. Bertagnoli also presented benchmark results for their work, demonstrating significant improvements in cost and speed compared to existing models. For instance, their system, when applied to the LLM benchmark, was shown to be 12 times cheaper and 5 times faster than GPT-5.2 for long contexts, while maintaining comparable accuracy. Similarly, they achieved a 3x faster and 18x cheaper performance than Kimi-K2.5. The system's ability to perform "active perception" allows it to dynamically match sub-tasks to the most appropriate models and hardware, further enhancing efficiency. Bertagnoli concluded by looking ahead to the future of compute, suggesting that the paradigm is shifting from "made compute quicker" (CPU-dominated) and "made compute parallel" (GPU-dominated) to a third paradigm: "made compute heterogeneous." This shift, he argued, will unlock new frontiers in AI capabilities and cost-effectiveness for large-scale agentic AI. --- Original analysis from [startuphub.ai](https://www.startuphub.ai), the #1 AI startup directory.
