AI Pioneer Sutton Says Synthetic Data Is"Big mistake": The world is infinitely complex; LLMs hit the data wall

Turing Award winner Richard Sutton calls synthetic data a "big mistake" for scaling large language models. The world is infinitely complex, and any simulation of it is "microscopic," with human expertise acting as a bottleneck that blocks real scaling. Sutton's alternative is agents that learn continually from their own experience instead of relying on frozen models.

Unitree's STAR Market IPO valuation is about 50 billion US dollars, behind it is a circular financing model similar to the US AI industry

Unitree Robotics rose 460 percent in its Shanghai IPO, hitting a valuation of around $50 billion. But an FT report shows much of the demand for its robots comes from state-backed training centers that buy the machines and sell the resulting data back to the manufacturers, a circular business model that echoes the Nvidia criticism in the US.

Agent AI in government hits hard problem: deciding which decisions machines can make for people

The United Arab Emirates (UAE) has been early in adopting artificial intelligence for 9 years. It published a national AI strategy in October 2017 and, days later, created a ministerial post to run it, making Omar Sultan Al Olama the world’s first minister of state for artificial intelligence at 27. In the years since, it has built the digital identity, sovereign cloud and data-sharing layers most governments are still procuring. Agentic AI in government is where that head start either pays off or does not.

Use TRL and LoRA to audit preference bias on Anthropic HH-RLHF and fine-tune language models

In this tutorial, we design an end-to-end preference-learning workflow using the Anthropic HH-RLHF dataset and Direct Preference Optimization (DPO). We begin by preparing a robust Colab environment, loading and parsing chosen–rejected response pairs, and auditing the dataset for structural and length-based preference biases. We then run lexical shortcut diagnostics to determine whether surface-level linguistic patterns can separate preferred from rejected responses, prepare conversational data with tokenizer-aware length filtering, and construc

Terence Tao: AI may trigger the biggest crisis in mathematics since Gödel

In a new essay, Terence Tao warns that AI could push mathematics into a crisis on par with the foundational upheaval around 1900. What's being tested this time isn't mathematical truth but the values of the field: what counts as a contribution, what gets rewarded, and who did the work. His rule of thumb: a proof that no human can explain should be considered incomplete.
