I built a novel triple-hybrid LLM under 1B parameters for ~$50

Mateusz has developed a full pre-trained language model, Project Inkblot's Titan v1, combining Mamba SSM, Multi-Head Attention, and 32-expert MoE in a single decoder-only architecture under 1B parameters. The model, trained on a single NVIDIA L4 GPU for ~$50, achieves 27.5 validation perplexity and demonstrates efficient scaling via a single-line config update, with all components implemented from scratch in PyTorch. Titan v2's first training cycle is now complete, and dataset expansion is underway.

ScaffoldAgent: Utility-Guided Dynamic Outline Optimization

ScaffoldAgent introduces a utility-guided framework for dynamic outline optimization in open-ended deep research. It models outline evolution through Expansion, Contraction, and Revision operations, guided by a feedback mechanism that evaluates retrieval gain, structural coherence, and generation quality. Experiments show it improves long-form report generation and factual grounding compared to existing agents.

Synthetic Audio Framework Improves ATC Speech Recognition

A synthetic audio generation framework is introduced to address data scarcity in Air Traffic Control speech recognition. It uses neural techniques like Text-to-Speech and accent conversion to simulate non-native English accents, enhancing Automatic Speech Recognition performance. Experiments with the Whisper model on the ATCO2 corpus show reduced word error rates when fine-tuned with synthetic or mixed real-synthetic data.

Two-Stage Alignment Improves Math Tutoring Pedagogy

A two-stage alignment pipeline enhances large language models' pedagogical performance in math mistake remediation. The approach combines supervised fine-tuning with Direct Preference Optimization using synthetic data on scaffolding and factuality, outperforming base and existing tutoring models in both accuracy and teaching quality. Human evaluations show the model competes with a proprietary baseline, offering greater openness and reproducibility.
