+++ OpenAI is locking in 750MW of Cerebras compute over three years, signaling that even trillion-dollar valuations can't escape the brutal economics of training at scale. +++
+++ The US government simultaneously restricts and permits H200 exports to China while Beijing plays hard to get, creating a masterclass in how geopolitical theater intersects with semiconductor economics. +++
+++ Anthropic's new agent tool looks genuinely capable at delegating Claude's powers, though the prompt injection risks Simon Willison flagged suggest the real work happens after launch, not before. +++
"It has been shown that Large Reasoning Models (LRMs) may not *say what they think*: they do not always volunteer information about how certain parts of the input influence their reasoning. But it is one thing for a model to *omit* such information and another, worse thing to *lie* about it. Here, we..."

"Large Language Models (LLMs) can produce surprisingly sophisticated estimates of their own uncertainty.
