The Daily Clearing

Across the Stories

The cost reduction in AI inference and the superconductor research progress suggest a broader trend toward more efficient computational methods across fields.

Editor's Skeptic Note

This week's digest contains several exciting announcements, but readers should note that AI benchmarks are increasingly gamed, and superconductor claims have a poor track record. Healthy skepticism is warranted.

The Chinese AI lab's latest release activates only 37B of its 685B parameters during inference, achieving GPT-4 class performance at a fraction of the cost. The paper details a novel sparse attention mechanism.

• 37B active parameters from 685B total using Mixture of Experts
• Achieves 95% of GPT-4 performance on key benchmarks
• Training cost estimated at $5.6M (vs $100M+ for GPT-4)

Why it matters

Cost democratization could reshape the AI landscape, enabling smaller players to compete with tech giants on model capability.

Skeptic's Corner

Benchmark gaming is rampant in AI. Real-world performance on complex reasoning tasks remains to be seen. The training data composition is also undisclosed.

Anthropic's new flagship model introduces "extended thinking" - visible chain-of-thought reasoning that improves accuracy on multi-step problems by 23%.

• Extended thinking shows reasoning process in real-time
• 23% improvement on complex math and coding tasks
• Available through API with new thinking_budget parameter

Why it matters

Visible reasoning makes AI systems more auditable and helps users understand model limitations.

New Superconductor Candidate Shows Promise at Higher Temperatures

A hydride compound shows superconducting properties at -20°C under 100 GPa pressure. While still requiring extreme pressure, this represents significant progress toward practical applications.

• Superconductivity observed at -20°C (253K)
• Requires 100 GPa pressure (vs 267 GPa in previous work)
• Crystal structure confirmed via X-ray diffraction

Why it matters

Reducing pressure requirements is key to making superconductors practical. This is incremental but meaningful progress.

Skeptic's Corner

Previous "breakthroughs" in this field have failed replication. The extreme pressure requirement still makes this impractical. Let's see if other labs can reproduce.
