An exploratory, single-seed ablation of TALH (Adaptive Latent Hybrid), a decoder-only language model with parallel Multi-head Latent Attention (MLA) and a custom recurrent state-space (SSM) branch supports implementation-specific hypotheses rather than general conclusions about MLA, SSMs, or mixture-of-experts models.
Slicing a byte-level BPE tokenizer allows one language model to operate at several vocabulary sizes, use a control token to indicate the active size, and be deployed at any trained size by slicing its embedding and output head, yielding a falsifiable prediction for future work.
A conventional all-attention model of the same size on the same data and a conventional all-attention hybrid that beats GPT-2 124M, Pythia-160M, OPT-125M and GPT-neo-125M, and exceeds MobileLLM-125M's published score despite that model seeing a trillion tokens.
Intent-Driven Dynamic Chunking (IDC) is introduced, a novel approach that uses predicted user queries to guide document segmentation and aligning document structure with anticipated information needs significantly boosts retrieval performance, particularly for long and heterogeneous documents.
