Claude, GPT-5, and Gemini each have coding strengths. But the model is only half the equation — context quality determines more of the output than model choice.

Claude Opus 4.6 is the most capable coding model available. But capability without context is expensive. Here's when Opus matters and when context matters more.

The best AI coding setup in 2026 isn't one tool — it's three: an agent for execution, a context engine for intelligence, and an IDE for interface.

Agentic coding means AI agents that autonomously explore, plan, write, and test code. Here's how it works, what's changed in 2026, and where context fits in.

The AI coding stack in 2026 has three layers: the agent (Claude Code, Codex), the IDE (Cursor, Windsurf), and the context layer. All three matter.
