🎮 The Next Input — 29 Jun 2025

👾 Good evening, builders!
Claude just invaded every IDE—Sonnet 4 and Opus 4 are live in Copilot. Strap in.

⚡ XP Boost | Anthropic ships Claude Sonnet 4 + Opus 4 to GitHub Copilot

— Sonnet 4 matches GPT‑4 Turbo on HumanEval (88 %)
— Opus 4 edges past (89 %), runs tool‑use chains out‑of‑the‑box
— 1 M‑token context window for both models

Why it matters
— Pick Sonnet 4 for fast coding loops (huge context)
— Use Opus 4 for agent workflows; vision prompts inside Copilot Chat
— Pay‑as‑you‑go via Anthropic API or free for Copilot Pro+ users

🔑 TL;DR → Claude just went mainstream for devs—no waitlist, no extra cost.

🎯 Builder Input (≤ 3 min)
