Local branching for scaling LLMs at inference time
An approach proposes generating previews of possible next tokens, choosing a branch, and continuing generation. The report describes gains in mathematical reasoning against three comparison methods.
A research paper presents Local Branch Routing, an approach to expanding language-model generation during inference. It creates previews of possible next tokens and arranges them into branches.
The system selects one of these options and continues generation from it. According to the report, the approach keeps the model trainable while adding branches at inference time.
The post reports improved mathematical reasoning compared with Chain of Thought (CoT), standard RLVR, and soft-token branching. It provides no metrics or further details to assess the size of these gains.
