A foundation model alone cannot edit files, run test suites, or debug code. Explore how modern coding agent harnesses like OpenCode, Claude Code, and DeepSeek scaffold raw LLMs with tool dispatch loops, subagent pipelines, and context compaction engines.
A hands-on engineering guide to LLM tokens. We break down Byte-Pair Encoding quirks, hidden whitespace costs, prompt caching mechanics, and the exact context architecture that reduced our production AI bill by 68%.
I spent 30 days building the same project with Cursor, GitHub Copilot, and Claude Code. Here's my brutally honest comparison, including which one I actually kept using, where each one fails, and the exact scenarios where one beats the others by a mile.
Agentic AI is the biggest trend in artificial intelligence for 2026. Learn what autonomous AI agents are, how they differ from chatbots, real-world use cases, and why every developer should pay attention.
