Researchers demonstrate that large multimodal models develop internal visual representations when solving spatial reasoning tasks, improving puzzle-solving accuracy from 83% to 89% by integrating visual tokens into chain-of-thought reasoning.

Researchers developed a method to measure when language models stabilize their answer preferences during generation, before explicitly verbalizing a final answer. Using finite-answer projection analysis on the Qwen3-4B-Instruct model, they found answer preferences stabilize 17-31 tokens before the model states its answer, revealing the internal commitment dynamics of LLM reasoning.
Researchers analyzed internal mechanisms of LLM-based agent memory systems across the Qwen model family, discovering that routing circuits activate before content extraction circuits—a critical gap in small models.

Alibaba has discontinued the free tier of its Qwen Code service, marking another reversal in Chinese AI companies' open-source commitments.
