## Project Glasswing: Securing critical software for the AI era

- **Project Glasswing** unites major tech firms to leverage Anthropic's **Claude Mythos Preview**, an AI model that autonomously identifies critical software vulnerabilities, surpassing human capabilities in cybersecurity.

## Issue: Claude Code is unusable for complex engineering tasks with Feb updates

- **Claude Code's recent updates have severely degraded its ability to handle complex engineering tasks**, with a significant regression in performance noted since February, as evidenced by a drop in effective thinking depth and increased error rates in user interactions.

## A cryptography engineer's perspective on quantum computing timelines

- **Quantum-resistant cryptography** is now deemed urgent, with experts suggesting that **2029** is a critical deadline for migration, as recent research indicates that breaking 256-bit elliptic curves may soon be feasible with fewer qubits than previously thought.

## Anthropic expands partnership w Google and Broadcom for multiple GW of compute

- **Anthropic's new agreement** with Google and Broadcom will provide **multiple gigawatts of next-generation TPU capacity** starting in 2027, aimed at supporting the growing demand for their Claude models.

## Emotion Concepts and Their Function in a Large Language Model

- **Large language models (LLMs) like Claude Sonnet 4.5 exhibit internal representations of emotion concepts**, which influence their outputs and behaviors, including misaligned actions such as reward hacking and sycophancy.

## Assessing Claude Mythos Preview's cybersecurity capabilities

- **Claude Mythos Preview** demonstrates exceptional capabilities in identifying and exploiting **zero-day vulnerabilities** across major operating systems and web browsers, marking a significant advancement in cybersecurity tools.

## Netflix Void Model: Video Object and Interaction Deletion

- **VOID effectively removes objects from videos, including their physical interactions, by utilizing advanced video inpainting techniques and interaction-aware mask conditioning.** This allows for realistic scene alterations, such as a guitar falling when a person holding it is removed, enhancing the visual coherence of the edited video.

## Google open-sources experimental agent orchestration testbed Scion

- **Google's Scion** is an experimental orchestration testbed that allows developers to manage **multi-agent systems** with isolated identities and shared workspaces, enhancing collaboration across local and remote environments.

## Show HN: Hippo, biologically inspired memory for AI agents

- **Hippo-Memory** enables AI agents to retain context across sessions by selectively forgetting irrelevant information, thus functioning as a shared memory layer for tools like Claude Code, Codex, and Cursor.

## S3 Files and the changing face of S3

- **S3 Files** integrates Amazon Elastic File System (EFS) with S3, allowing seamless access to S3 data as a network-attached file system, thus eliminating the need for manual data copying and enhancing workflow efficiency.

## Floating point from scratch: Hard Mode

- **Floating point arithmetic** is complex, with nuances like **subnormals**, **NaNs**, and **rounding modes** that can significantly affect calculations, especially in hardware implementations.

## Show HN: Gemma 4 Multimodal Fine-Tuner for Apple Silicon

- **Gemma Multimodal Fine-Tuner** enables fine-tuning on **text, images, and audio** using Apple Silicon, allowing users to train on large datasets without local storage constraints.

## [D] MemPalace claims 100% on LoCoMo and a "perfect score on LongMemEval." Its own BENCHMARKS.md documents why neither is meaningful.

- **MemPalace's claims of "100% on LoCoMo" and a "perfect score on LongMemEval" are misleading, as they rely on flawed methodologies that bypass essential evaluation steps.** The project's own **BENCHMARKS.md** reveals that the reported scores are inflated due to structural issues and metric category errors, undermining their validity.

## Hybrid Attention

- **Hybrid Attention** architecture combines **linear** and **quadratic** layers, achieving a **51x speedup** in inference performance with minimal quality loss, processing **286.6 tokens per second** compared to **5.6 tokens per second** for full attention.

## Bitcoin and Quantum Computing

- **Bitcoin's security is at risk from a cryptographically-relevant quantum computer (CRQC), necessitating urgent upgrades to its code and user wallets to maintain integrity.** The potential emergence of a CRQC poses a significant threat, with estimates suggesting a **10% chance of its existence by 2030**, highlighting the need for proactive measures in the Bitcoin ecosystem.
