Opus 4.8 Lands, Cipher Cracked After 500 Years

Today's AI news lineup: Anthropic's Opus 4.8 launch and token economics, Sakana Labs' diffusion-block pre-training, an AI cracking a 500-year-old diplomatic cipher, and Cognition's $1B raise for Devin.

The conversation opened on the freshly launched Opus 4.8, weighing Every's review against real-world token efficiency and cost, then moved into how the model reshapes compound-engineering workflows and sub-agent setups. From there it ranged widely: unsettling LLM survival simulations, a breakthrough from Sakana Labs that slashes pre-training compute by avoiding full-density back propagation, and a pair of "cool factor" stories where AI decoded a diplomatic letter that resisted decryption for over 500 years and shed new light on the ancient Antikythera mechanism. The funding picture loomed large too, with Cognition's $1B Series D for Devin and Anthropic's $65B raise at a $965B valuation prompting a hard look at the token economics underneath it all, before wrapping with weekend AI resources to dig into.
