Sakana AI introduces a new class of AI models called Continuous Thought Machines (CTMs), designed to mimic dynamic and adaptive human thinking more closely than conventional transformer models. These models combine principles from nature and neuroscience, embracing fluid computation instead of fixed-step processing. CTMs show early promise in tasks that require ongoing reasoning, memory, and flexibility—traits lacking in today's most popular AI architectures.
Modern transformer-based models, like those used in Chat GPT, process information in discrete steps and lack continuous feedback, limiting their reasoning and adaptability. Inspired by biological brains and natural systems such as fish schools and bird flocks, Sakana AI proposes CTMs as an architecture that learns to think in a continuous and self-evolving way. This nature-inspired mechanism reflects Sakana's broader philosophy of nature meets AI, with models that learn, adapt, and interact over time—similar to living organisms.
In a task where the model must navigate mazes, CTMs outperform transformers by generating better internal representations and adapting their thinking as they "move" through the maze. The visualization of the CTM’s internal states over time shows a clear sense of progression and refinement, akin to how humans update their thoughts as they receive more information. This showcases CTMs' capacity for stateful, context-aware computation, a key leap forward.
CTMs were also tested on image classification tasks, where each layer of the model processes and refines its "thoughts" continuously. Instead of treating image recognition as a one-shot process, CTMs iteratively refine their understanding, much like how a person might look twice to be sure. This iterative reasoning leads to higher accuracy, especially in complex or ambiguous images.
Sakana AI sees CTMs as a foundational shift in how we build intelligent systems—moving away from rigid, discrete computations and toward continuous, adaptive thought. The team envisions future AI that can think more fluidly, reason more deeply, and adapt like living organisms. Their commitment to combining biological principles with cutting-edge machine learning is a bold step in the evolution of AI.
