Why AI Coding Companies Are Reworking Code Hosting Infrastructure
QbitAI reports that OpenAI, Cursor, and Anthropic are building or expanding code hosting systems as AI coding increases infrastructure workloads, while GitHub upgrades its own services. OpenAI’s Pando handles internal Git traffic, and it plans to bring Pierre’s code storage capabilities into Codex after its acquisition closes. Anthropic moved its main codebase to Scion, while Cursor’s Origin offers developers another hosting option.

Vals AI Benchmarks Show Open Models Closing the Cyber Capability Gap
Vals AI’s CyberOffense benchmark finds that Deepseek V4.1 Flash 1017 approaches GPT-6 Sol Daybreak in the Nova test and completes 21 of 31 objectives in the harder Lighthouse scenario, compared with Daybreak’s 27. The report says Deepseek costs about $3 per Nova run versus roughly $22 for Daybreak, and that its Lighthouse progress came mostly after 100 million tokens. The results align with an AI Security Institute analysis that put the open and closed model gap at four to seven months.

Jeff Dean and Fei-Fei Li Discuss Recursive Self-Improvement and Its Limits
In a Stanford HAI talk and conversation with Fei-Fei Li, Jeff Dean said automated research systems can speed up parts of model development but cannot make recursive self-improvement run infinitely fast, because training, computation, data storage, and evaluation take time. He also described Discovery Loop, his new company, which he said has about 20 automated improvement loops running and aims to increase domain experts’ productivity by 20 to 50 times.

Alex Stamos on AI’s Cybersecurity “Dark Age” and What Could Shorten It
In a Decoder interview, Cognition chief security officer Alex Stamos argues that AI is making cyberattacks faster and cheaper by helping attackers find vulnerabilities and write exploits in real time. He says defenders need cheaper ways to monitor and respond to attacks, alongside automated bug fixes and, in some cases, rewriting vulnerable legacy software. Stamos describes the current period as a “dark age” and points to fewer major breaches and critical infrastructure vulnerabilities as signs of progress.
