Unreleased Claude Model Improves Riemann Hypothesis Bound

On Aug 11, Anthropic announced that an unreleased Claude research build raised the Riemann zeta lower bound from 41.6% → 67.2% — one of math's most famous unsolved problems.

The run:
🧠 Non-mathematician prompted it with "take a real stab at the Riemann hypothesis"
🤖 60 autonomous subagents coordinated via Claude Code
⌨️ 2,400 shell commands, hundreds of Python scripts
📄 54 arXiv papers reviewed and connected
💰 31M output tokens (~$37 API cost)
❌ 650 failed ideas before the breakthrough

Why developers should care:
1️⃣ Autonomous multi-agent workflows are production-ready — human sets direction → AI explores → AI generates code → AI runs experiments → AI iterates
2️⃣ Claude Code = autonomous execution environment — not just a coding assistant, but an orchestration layer
3️⃣ Cost-performance is transformative — $37 for a novel mathematical result

Action: Try giving Claude Code a complex debugging task and letting it run autonomously. Set a generous context, give it repo access, and let it explore.
