Signal of the Day#

Anthropic launched Project Glasswing, an urgent cybersecurity initiative powered by its new, unreleased frontier model, Claude Mythos Preview. The project unites major tech and financial players—including Amazon Web Services, Apple, Google, Microsoft, NVIDIA, and JPMorganChase—to systematically find and fix flaws in critical software before models of this capability become widespread.

Key Announcements#

Anthropic · Source Anthropic introduced Claude Mythos Preview, a specialized model capable of finding software vulnerabilities at a level matching highly skilled humans. Backed by up to $100M in usage credits, the initiative partners with tech giants and open-source maintainers to secure global systems. Notably, Mythos Preview will not be made generally available; Anthropic is instead testing safety guardrails for the system on an upcoming Claude Opus model.

Tesla / Intel · Source Intel has officially joined Terafab, a massive semiconductor fabrication initiative partnered with Tesla, xAI, and SpaceX. The project aims to consolidate logic, memory, and advanced packaging under one roof to produce 1 terawatt per year of compute, specifically targeting the acceleration of AI and robotics advancements.

Microsoft / Bing · Source Microsoft’s search team open-sourced Harrier, a new embedding model that currently ranks first on the multilingual MTEB-v2 benchmark. Designed for semantic search and AI agent RAG workloads, Harrier supports over 100 languages and processes long inputs up to 32K tokens, outperforming current models based on Gemini, Llama, and Qwen.

Google · Source Google released Gemma 4, which is capable of running locally on mobile phones without an internet connection. Available through the Google AI Edge App on iOS and Android, the model can execute local agentic tasks like logging and trend analysis, and natively make API calls when the device is reconnected.

Z.ai (Zhipu) · Source Z.ai launched GLM-5.1, a new open-source model that ranks top-tier across SWE-Bench Pro and Terminal-Bench. The model is built specifically for long-horizon autonomous tasks, capable of running independently for up to eight hours to refine strategies across thousands of iterations.

Exa / Coinbase · Source Exa partnered with Coinbase to launch x402, an open protocol governed by the Linux Foundation that enables AI agents to natively pay for web search. When an agent makes an API request without a key, Exa returns a 402 HTTP status code with actionable payment information that the agent can fulfill autonomously.

AWS · Source AWS announced Amazon S3 Files. The launch brings fully-featured, high-performance file system access directly to its cloud object store, merging the scalability of S3 with standard file system capabilities.
