A new approach to language models exploits latent reasoning to scale computation without depending on token generation. A recurrent network allows processing to deepen dynamically, improving performance with limited resources.

Key points:

• Latent reasoning: The model processes information in latent space, separating internal computation from visible context.
• Dynamic depth: The architecture uses a recurrent block to iterate and deepen reasoning without generating multiple tokens.
• Computational efficiency: Even relatively small models achieve high performance without extended context windows.
• Test scalability: The model dynamically adapts to the complexity of the task, reducing dependence on specific datasets.

The latest evolution in the field of language models introduces a new paradigm based on latent reasoning, an innovation that allows the computation to scale without increasing the length of the processed sequence. Unlike traditional approaches that improve inferential capacity by generating increasing numbers of tokens, this methodology exploits a recursive architecture capable of deepening reasoning internally, without impacting observable context. At the heart of the model is a recursive block that can be unrolled to arbitrary depth in testing, modulating the degree of processing according to the need of the task. This mechanism enables implicit reasoning to be enhanced by capturing logical structures and relationships that are difficult to represent explicitly by text.

The absence of structural dependence on large context windows is a significant step forward from current chain-of-thought-based methods, which require training on specialized data to achieve optimal results. In this case, the model demonstrates the ability to refine its processing through a variable number of iterations in the latent domain, without the need for additional textual information. This results in increased computational efficiency, paving the way for advanced implementations with limited resources and improving performance without the requirement to expand the number of parameters.

A large-scale experiment applied this principle to a 3.5-billion-parameter proof-of-concept model trained on 800 billion tokens. The results obtained show that latent reasoning allows the model to achieve performance levels typical of architectures with up to 50 billion parameters, without requiring the exponential increase in computational capacity.

The impact of this finding is significant: the ability to perform deeper reasoning without compromising efficiency and scalability represents a significant advance in generative AI, with potentially groundbreaking implications for the entire field.
