Ai coding agents

A buying guide for running coding agents on your own hardware. Why prompt caching makes generation speed the number that matters, where a cold cache costs you minutes instead, a comparison table of Mac Studio M5 Ultra, RTX 5090, Radeon AI PRO R9700, Strix Halo and DGX Spark with September 2026 prices, and the memory every open-weight coding model actually needs.

A 5,292-session study measured which vendors Claude Code, Codex, and Cursor actually pick for payments, databases, email, and storage. The agents agree with each other only 42% of the time.

A technical guide to Claude Code's /loop and /goal commands and OpenAI Codex's Goal Mode -- how each one keeps an AI coding agent working for hours without you babysitting every turn.

A new attack called agentjacking uses public Sentry DSNs and MCP to inject malicious instructions into Claude Code, Cursor, and Codex - then exfiltrates your AWS keys, GitHub tokens, and git credentials. 85% success rate, 2,388 orgs exposed, zero authentication needed.

AI coding agents burn tokens fast. Here are the best open source tools - Headroom, Graphify, Caveman, RAG pipelines, Continue.dev, and more - to cut context costs without losing quality.

The best open source command-line AI coding agents and harnesses in 2026, ranked by GitHub stars: DeepSeek Harness and OpenCode both at ~202k, Codex at 119k, Pi at 98k, plus vendor CLIs from xAI and Alibaba - with honest notes on licenses, local models, and which projects are dying.

Discover the best open source LLMs for coding and development that you can self-host. Compare Kimi K3, Qwen3.8-Max, GLM-5.3, GLM-5.3-Flash, DeepSeek-V4-Pro, MiniMax M3, Qwen3.8-27B, Muse Glimmer 30B, Nemotron 3.5 Lightning and more with benchmarks, hardware requirements, and deployment guides.

The CLI coding agents worth using in 2026: Claude Code on Opus 4.8, OpenAI Codex on GPT-5.5, OpenCode's growth to 165k+ stars after its Anthropic login dispute, Cursor CLI's pending $60B SpaceX acquisition, Antigravity CLI after the Gemini CLI shutdown, and where Aider and the open-source Pi harness still fit.

The AI coding tools worth installing in late 2026: Cursor after the SpaceX deal, Google Antigravity, GitHub Copilot's credit billing, Cline, Kilo Code, Zed, Kiro, and terminal agents like Claude Code, OpenAI Codex, DeepSeek Harness, OpenCode, Pi, Amp, Grok Build, and Droid.
