Last verified: September 2026. Every other guide on this site assumes you've chosen Claude. This one is for before that — the choosing itself. Benchmarks, crowd consensus, the honest alternatives list, and the one head-to-head that matters most for developers. Four deep dives, one hub.

A primary-source coding leaderboard for the top models of June 2026 — Claude Fable 5, Claude Opus 4.8, GPT-5.5, and Gemini 3.1 Pro — with price and context alongside the scores. Benchmarks aren't the whole story, but they're the least biased starting point.
