AI Coding Assistants ROI in 2026 — The Honest Numbers
What AI coding assistants actually deliver in 2026. Where they save hours, where they create new work, the productivity research, and the adoption patterns of teams that ship faster vs teams that hit dead ends.
1M-Token Context Windows in 2026 — When They Help, When They Hurt
How to actually use 1M-token context windows. The ‘just put it all in context’ temptation, when it works, when RAG still wins, prompt caching, and cost.
Agentic RAG in 2026 — When Retrieval Becomes a Tool, Not a Pipeline
Why agentic RAG often beats one-shot RAG. Tool-based retrieval, decomposition, query rewriting, self-reflection, citations, and the production patterns that ship in 2026.
