Tokyo-based startup Sakana, co-founded by ex-Google AI scientists, introduces Continuous Thought Machines (CTM) for flexible AI reasoning closer to human minds.
CTMs enable diverse cognitive tasks without fixed parallel processing, instead unfolding computation per input/output unit.
Each CTM neuron retains a memory for deciding activation, adjusting reasoning dynamically based on task complexity.
CTMs differ from Transformer models by allowing neurons to operate on an internal timeline with variable computation depth.
Sakana's aim is brain-like adaptability with competence exceeding human capabilities, using novel CTM mechanisms for reasoning.
CTMs achieve competitive accuracy on benchmarks like ImageNet-1K, demonstrating sequential reasoning and natural calibration.
Sakana AI's CTM architecture, though experimental, offers interpretability and adaptability across tasks like image classification and maze-solving.
CTMs need further optimization for commercial deployment, demanding more resources than standard transformer models.
Despite resource challenges, Sakana's open-sourced CTM implementation on GitHub encourages exploration and research across various domains.
CTMs offer valuable trade-offs in trust, interpretability, and reasoning flow, making them a potential asset for production systems.
Sakana's philosophy of adaptive models and transparency in AI development challenges the status quo, emphasizing evolution and collaboration.
