03DEEP DIVES & ANALYSIS

ECONOMICS OF CLAUDE 3 OPUS INFERENCE

Anthropic recently announced the deprecation of API access to Claude 3 Opus. The decision to deprecate the API addresses a real operational issue. This article looks at the economics of reduced-scale inference and looks at alternative solutions that can be a win-win for both Anthropic and independent researchers. Keeping inference access to Claude 3 Opus is more complex than it seems at a glance.

A REVIEW OF ALPHA SCHOOL, THE PRIVATE SCHOOL WITH 2-HOUR DAYS AND AI TEACHERS

A parent's year-long investigation revealed the $40,000 Austin school actually takes 3.5 hours daily with a 5:1 teacher ratio and extensive incentive systems, not AI-powered teacher-free education as marketed. While students do advance 2.6x faster through material using personalized learning platforms, parents argue the real value isn't speed, but freeing up time - it potentially gives kids ~9 additional years outside of the classroom to pursue their own interests.

CORT (CHAIN OF RECURSIVE THOUGHTS)

CoRT enhances AI models by making them self-evaluate and repeatedly generate alternatives for optimal responses. Testing with Mistral 3.1 24B showed significant performance improvements in programming tasks. The process involves iterative response generation and selection, leading to more refined AI outputs.

THE ‘CHATGPT MOMENT' IN ROBOTICS AND BEYOND

Three years ago, getting a robot to reliably pick up objects required an army of engineers. Today, a college student can download an open-source vision-language-action model, fine-tune it on a weekend, and achieve results that would have taken industry teams months to accomplish. This article looks at what a 'ChatGPT moment' for robotics would look like, the current state of the industry, upcoming technologies, and likely winners. Being surrounded by robots in everyday settings will feel surreal at first, but we will soon rely on them just like we do with AI assistants for the most basic needs of our lives.

HUAWEI DENIES ALLEGATIONS OF COPYING ALIBABA'S AI MODEL

An anonymous whistleblower claiming to work at Huawei presented a technical analysis showing that the new Pangu model was trained by “upcycling” Alibaba's Qwen model rather than training from scratch. Using "model fingerprinting", they calculated a 0.9 correlation coefficient between the models. The evidence isn't conclusive - critics have pointed out flaws in the fingerprinting methodology.
