Anthropic released Claude Opus 4.7 on April 16, 2026, touting frontier-level gains in agentic coding, long-horizon tasks, instruction following, self-verification, and high-resolution vision processing, with a 13% uplift on its 93-task coding benchmark over Opus 4.6. By April 17, the large language model debuted on Arena.ai leaderboards, surging to #1 in Code Arena—+37 Elo points ahead of Opus 4.6 and a massive 130-point lead over GPT-5.4 and Gemini 3.1 Pro—while advancing the price-performance frontier in Text Arena.
