Claude Code Wrote a Better AI Scaling Algorithm Than Humans Could — For $40
Researchers from several universities and tech companies developed AutoTTS, a system where Claude Code autonomously discovers test-time scaling algorithms for LLMs rather than having humans design them manually. Operating within a pre-built simulated environment, the AI agent iteratively writes and refines control algorithms, ultimately producing one that reduces token usage by ~70% compared to standard methods while maintaining accuracy. The entire discovery process cost around $40 and took under three hours, and the resulting algorithm uses a dynamic confidence-tracking logic that the authors say would have been nearly impossible for humans to design themselves.
How a Lobster Mascot and a Bunch of Obsessives Dragged the AI Agent Era Into Existence
In late 2025, Anthropic's Claude Code — particularly the Opus 4.5 release — ignited a wave of AI agent enthusiasm among technically skilled users, enabling individuals to build and oversee complex software at a scale previously requiring entire teams. Alongside it, developer Peter Steinberger created OpenClaw, an open-source personal AI agent that became the fastest-growing project in GitHub history, drawing mainstream tech attention including a prominent endorsement from Nvidia's Jensen Huang. While the tools remain imperfect, risky, and expensive, they signal a broader shift toward autonomous AI agents that could soon reshape how all computer users work — and potentially displace many jobs in the process.
DeepSeek Is Building Its Own Coding Agent to Take On Claude Code and Codex
Deepseek is developing a new AI coding agent called "Deepseek Code," designed to compete directly with Anthropic's Claude Code, OpenAI's Codex, and Cursor. The Chinese AI company is forming a dedicated "Harness" team in Beijing, hiring a product manager and developer to build the agent's tooling, planning, and memory capabilities around its existing models. Candidates are expected to have hands-on experience with rival coding tools and expertise in areas like agent loops, multi-agent systems, and context engineering.
Anthropic Quietly Fixed a Claude Code Sandbox Bypass Nobody Told You About
Anthropic quietly fixed two vulnerabilities in Claude Code's network sandbox that could have allowed attackers to bypass network restrictions and exfiltrate sensitive data. The second flaw, discovered by researcher Aonan Guan, involved a SOCKS5 null-byte injection trick that could fool the allowlist filter into permitting connections to unauthorized hosts. Guan has criticized Anthropic for lacking transparency, noting no CVE was assigned to his finding and no public disclosure or release notes warned users — though Anthropic states the fix was deployed before his bug bounty report was submitted.
