Codex Security: How a Security-Researcher-Style Agent Finds, Validates, and Fixes Repo Vulnerabilities

Codex Security combines a repo-aware threat model, sandbox validation, and minimal patch suggestions to reduce false positives. Its open-source CLI and TypeScript SDK let teams scan owned repositories, export findings (including SARIF), and integrate security checks into CI or pre-commit hooks.

From Softmax to Kimi Delta Attention: the “obvious” path you missed

Kimi Delta Attention (KDA) turns attention into a recurrent “fast-weight” state update. By starting from softmax attention, removing the softmax bottleneck, then adding delta-rule correction and diagonal (channel-wise) forgetting, KDA becomes an almost inevitable refinement of linear attention.

Translating Ancient Astronomy: A Practical Blueprint for AI-Ready Texts

Translating rare Hebrew and Latin astronomy texts isn’t just about language. A real pipeline must preserve exact sexagesimal math, tabular values, and diagram structure while tracking uncertainty and reconciling discrepancies. Ars Astronomica’s approach shows how AI-assisted translation can be engineered for manuscript-grade fidelity.

MAI-Cyber-1-Flash inside MDASH: AI that proves vulnerabilities (not guesses)

MAI-Cyber-1-Flash inside MDASH aims to make AI vulnerability discovery evidence-first. Instead of guessing, the multi-agent harness prepares, scans, validates, deduplicates, and proves bugs—while routing work to control token cost. The result is a security workflow built for continuous defense, not occasional scanning.
