About Terminal-Bench: Evaluates AI agents on real command-line tasks — package management, build systems, git, server config, file manipulation, shell scripting. 🟢 2.1 = official tbench.ai or Anthropic-verified. 🟡 2.0 = vendor-reported from model cards. Scores NOT directly comparable across versions — 2.1 is harder.
🆕 GPT-5.6 Sol leads at 88.8% (2.1) — OpenAI also reports 91.9% with its four-agent Ultra configuration. Terra: 87.4%; Luna: 84.7%. These are OpenAI-reported results.
🆕 Claude Sonnet 5 debuts at 80.4% (2.1) — 97% of Opus 4.8 at 60% of the price. +13.4 pts over Sonnet 4.6. Anthropic System Card. $3/$15 per 1M.
GPT-5.5 remains a useful historical reference at 83.4% (Codex CLI, 2.1). GPT-5.3 Codex (77.3%, 2.0) still beats GPT-5.4 on terminal — Codex specialization holds.
