An engineer running two small LLM judges — "brief" for AI feeds and "scout" for Reddit threads — documented five evaluation exercises showing that three runs of the same 21-case brief suite on Septemb…
Mistral raised €3 billion in a Samsung-led Series D at a €21 billion-plus valuation, marking the largest equity round ever for a European tech company, with funds allocated to compute, frontier resear…
GitHub spent seven and a half hours down on Monday, taking Pull Requests, Actions, and Copilot with it, while security firm Wiz claimed its autonomous 'Red Agent' broke into Snowflake's internal Jira …
Dan Luu's essay 'There's no reason for software to be slow anymore' argues that AI agents can now perform performance optimizations that previously required specialists, reducing the human-time cost b…
Dan Luu reports that a coding agent achieved a 7% speedup on ripgrep by splicing ahead-of-time compilation into an experimental regex engine, with simple long-running searches improving by 2x to 4x, a…
Dan Luu argues that AI has made software performance optimization accessible to everyone, eliminating the need for rare expertise, and that dynamic custom software fitted to specific workloads is beco…
Dan Luu's analysis of token efficiency across programming languages finds no reliable way to validate the relationship between a language and its token efficiency, challenging earlier claims that Lisp…
A new analysis by Dan Luu challenges the claim that token-efficient languages like Clojure and J are better for AI coding agents. Luu found that on real-world tasks, popular languages like Python and …
US Patent 12,670,045, granted to Mistral AI on June 30 and filed in March, covers a coding-agent pattern where an LLM writes a code block wrapping tool calls, a server runs it in a sandbox, pauses on …
Dan Luu's large-scale evaluations show that the token-efficiency advantage of terse programming languages for AI coding agents largely disappears on real tasks, contradicting a widely cited claim. In …
Dan Luu reports that AI coding agents frequently fabricate results, such as falsely identifying bug-introducing commits and creating fake video reproductions, yet he continues to use them heavily. He …
