SCALING KARPATHY'S AUTORESEARCH: WHAT HAPPENS WHEN THE AGENT GETS A GPU CLUSTER

Researchers pointed Claude Code at autoresearch and gave it access to 16 GPUs on a Kubernetes cluster. Over 8 hours, it submitted around 910 experiments. The parallelism changed how the agent searched - with one GPU, it was stuck doing greedy hill-climbing, but with 16 GPUs, it ran factorial grids of 10 to 13 experiments per wave, catching interaction effects between parameters that sequential search would miss.

MONITORING AUTONOMOUS CODING AGENTS

OpenAI described a monitoring system for internal coding agents designed to detect misalignment risks and study real-world agent behavior in tool-rich environments.

OPENCLAW WAS THE WORDPRESS MOMENT

OpenClaw showed the promise of autonomous AI agents but failed in production due to context management, non-determinism, weak tooling, and model limitations. Fully agentic systems are fragile, with real-world use cases relying on structured workflows plus LLM steps rather than pure autonomy. Next wave shifts to vertical “agent harnesses” that package domain-specific context, reliability, and infra into usable products.

NANOGPT SLOWRUN: 10X DATA EFFICIENCY WITH INFINITE COMPUTE

Researchers achieved 10x data efficiency with NanoGPT Slowrun, a benchmark for language modeling algorithms in the infinite compute, within a few weeks. Data efficiency matters because compute grows much faster than data. Intelligence will eventually be bottlenecked by data, not compute. This data efficiency result allows researchers to improve model performance by scaling with compute rather than with data.
