TEACHING AN LLM A NICHE DIAGRAMING LANGUAGE

A 7B language model (Qwen2.5-Coder-7B) was successfully trained (with 86% accuracy) to generate and edit diagrams using the less popular Pintora language. The training involved continued pretraining on Pintora diagrams, followed by instruction fine-tuning. Data was generated by an AI agent, cleaned, and used to train the model with limited resources on Google Colab and Runpod.

STACKING DEPENDENCIES

Inspired by the XKCD comic about software dependency towers, this dev created a tool to visualize dependency graphs as physical towers. He encountered an NP-hard problem that required him to explore graph theory and various algorithms, ultimately combining a barycentric heuristic with PQ-tree pruning for fast layout generation. The resulting tool normalizes the dependency graph and then renders it as stackable towers with information about maintainers.

BUILDING DEEP RESEARCH: HOW WE ACHIEVED STATE OF THE ART

Tavily rebuilt its research agent from scratch after overengineering the first version with assumptions that broke when new models arrived. Instead of passing all tool outputs through the agent loop like most systems do, it distilled outputs into compact reflections and only loaded raw sources for final generation. This cut token usage by 66% while hitting SOTA on benchmarks.
