Python – LLM Quantization with Qwen3

Vitosh Sep 9, 2026 Tagged with ai, llm, Python, quantization, qwen, small language model

Quantization is one of the most common techniques to make language models smaller and more practical. The idea is simple – instead of storing model weights with high numerical precision, these are replaced with lower precision approximations. This reduces the …

Breadth-First Search (BFS) algorithm with Python

Vitosh Dec 3, 2025 Tagged with ai, bfs, Python

BFS, DFS, A-Star – these sound like magic spells from a Harry Potter book! And actually, these are magical (especially the A-Star) as far as they are well-defined algorithms, that explore a graph. In our previous article, we have explored …
