Active learning selects the most informative unlabeled samples for human annotation. This tutorial covers uncertainty sampling, diversity-based sampling, and qu

Learn how a feedback loop escalates PDF parsing from cheap to deep only when needed, using LLM self-evaluation to catch silent parse failures.

AI agents face unique security threats like prompt injection and tool misuse. Learn five foundational defense strategies to mitigate them.

Claude Fable 5 has limited weekly usage. Learn how to reserve it for planning and refactoring while using other models for implementation.

Seven Python tools engineers are using in 2026 to build and run AI agents on local infrastructure, from model runtimes to full orchestration frameworks.

Anthropic releases Claude Sonnet 5 as the free default model for all users, with stronger agentic capabilities, lower API costs, and improved reliability.

A routing layer cut AI inference costs by 60%. Three months later, the quality loss was costing four to five times the savings.

Learn how to capture information from multiple sources into an LLM-powered knowledge base and query it automatically using coding agents.

A three-stage RAG retrieval pipeline runs keyword and embedding detectors in parallel, then resolves candidates with a single LLM call.

A real data preprocessing task shows where human problem-solving ends and AI assistance begins - and why the gap matters.

Learn three practical NLTK techniques—MWE tokenization, POS-aware lemmatization, and collocation extraction—to improve text preprocessing pipelines.
