Exo is a fully recursive AI agent harness that can safely edit all aspects of itself at runtime—prompts, memory, tools, policy—with full visibility into its own code and logs, and achieved a 96% cost reduction through self-optimization in production.

TechCrunch reports General Intuition — building a foundation model that teaches AI agents to move through space and time — is in talks to raise at a $6B pre-money valuation from Valor Ventures, Point72 Ventures and Seven Seven Six.

Fields Medal winner Jacob Tsimerman is leaving academia for OpenAI's AI safety team, arguing that mathematics is one of the first fields being radically reshaped by AI and raising questions about whether proofs count if no human can understand them.

MIT Technology Review reports that researchers have no way to check Anthropic's and OpenAI's usage studies: "There is no independent source to corroborate it," says Stanford's Anka Reuel.

Clippy, a free macOS app, surfaces approval requests and questions from Claude Code and Codex agents via a small animated buddy on each window, using localhost hooks that fail safely to the terminal prompt if the app is closed or unresponsive.

Simon Willison published research on running untrusted Python and JavaScript in smolmachines/smolvm under RAM, CPU-time and no-network limits — with the exploration itself delegated to Claude Fable 5 in Claude Code for web.

OpenAI cut GPT-5.6 Sol API pricing effective until at least November 21, announced via a quiet update to its developer pricing docs rather than a formal post.

Ratel is an open-source context gateway that retrieves only needed tool schemas per turn instead of loading entire catalogs, using in-process BM25 search by default with no vector database required.

OtterlyAI's Agent Analytics reads server logs to show which AI crawlers fetched which pages — traffic that is invisible to JavaScript analytics — and lines it up against whether the brand gets cited in AI answers.
Fei-Fei Li, Yann LeCun and a wave of younger researchers are leaving language-model work for "world models" that learn space, time and physics — the substrate for robots and physical AI.

Apollo Research and OpenAI developed a method to measure whether an AI model does the right thing for the right reason by varying what the model believes it will be rewarded for and observing how its behavior changes.

Google claims homomorphic encryption is now practical for private AI workloads, drawing 473 points on Hacker News in 28 hours as engineers debate whether the performance overhead makes the pitch credible.

Cursor announced Origin on August 17, a code-hosting product that puts it in direct competition with GitHub, and the launch drew 556 points and 406 comments on Hacker News.

Speko, a YC S26 company, launched on Hacker News on August 17 pitching itself as "OpenRouter for Voice AI" — a single routing layer in front of voice providers — and drew 117 points and 67 comments.

OpenAI dropped GPT-5.6 Sol's API pricing by 20%, shipped as a quiet documentation update on August 22 rather than an announcement — the model page is the only notice.
Researchers introduce Program-of-Layers (PoLar), a training-free framework that dynamically skips, keeps, or repeats transformer layer segments per input, achieving up to 87.8% on DART-Math with Qwen2.5-3B, without modifying base model weights.

fx, a self-described tiny, open, native coding agent published at fx.sh on August 18, hit the Hacker News front page with 263 points and 112 comments.

Vomit, an open-source tool from developer zachahn, pipes Claude 5's token output through a separate LLM to clean it up — and hit the Hacker News front page on August 20 with 300 points and 291 comments.

A small GitHub project called Claudette, from the repo adnanakil/nobuzz, pitches itself as a fix for Claude's BuzzFeed-article register — and pulled 335 points and 217 comments on Hacker News in about a day.

Ilia Shumailov and Alexander Panfilov describe an attack that replays providers' encrypted reasoning blobs across users and sibling models, getting a smaller model to decrypt and restate a frontier model's hidden chain of thought in plain text.
