The quest for more efficient large language models (LLMs) continues, with a focus on reducing computational overhead without sacrificing performance. Current architectures often entwine knowledge storage and reasoning processes, leading to inefficiencies.

Knowledge-Reasoning Separation for Efficiency

Researchers have introduced the Mobius-v0 architecture, a novel framework designed to decouple knowledge storage from reasoning operations. This architecture comprises a globally shared Memory (FFN) for knowledge vectors and multiple Reasoners (Self-Attn) that engage in iterative compositional reasoning. Hidden states act as conduits, allowing reasoners to query memory for necessary knowledge vectors, which are then transmitted back to the reasoning operators. This clear separation is key to achieving better knowledge compression and enhanced reasoning efficiency.

Tangible Performance Gains

The practical implications of the Mobius-v0 architecture are substantial. A 7B model built from scratch using Mobius-v0 demonstrated comparable downstream performance to a standard 7B Transformer baseline, but critically, it achieved this using only 62.6% of the baseline's training data. Furthermore, Intern-S2-Mobius, a model continually pre-trained from Qwen3.5-35B using the Mobius-v0 architecture, matched downstream scores while delivering a nearly 4x end-to-end inference speedup. These results suggest a significant reduction in both training and deployment costs.
