MarkItDown is Microsoft's open-source Python library that converts PDFs, Word docs, Excel, PowerPoint, and 12+ formats to clean Markdown for LLM pipelines. 139K GitHub stars, 82% F1 accuracy, zero GPU required. Full setup guide with benchmarks.
Karpathy's Software 3.0 framework reframes how builders should think about AI products. The context window is your program, the LLM is the interpreter. Here's what that means — and what software should stop existing.
Karpathy published a pattern that fixes how builders manage knowledge. Instead of RAG, an LLM incrementally builds and maintains a persistent wiki. Here's the full architecture, operations, and how to start.
Gemini 3.5 Flash launched at Google I/O 2026 with Terminal-Bench 76.2%, 1M token context, 4x speed, and 2x cheaper pricing. Here is what that actually means for builders — where Gemini wins, where Claude still leads, and the dual-model workflow for 2026.
The World Economic Forum projects a net loss of 14 million jobs through 2027. But workers with AI skills already earn $28K more. Here's a 5-level roadmap to future-proof your career by becoming an AI-native builder.
Forget magic words. Prompt engineering is a learnable skill with clear principles. This guide covers chain-of-thought, structured outputs, role prompting, and the patterns that consistently get better results from Claude, GPT-4o, and Gemini.
Stop staring at blank docs. These AI workflows help PMs write sharper PRDs, generate user stories from interviews, run competitive analysis in 20 minutes, and prioritize roadmaps with data.
