OpenAI will acquire Pierre Computer Company, expanding Codex's tools for building, understanding, and reviewing code.
Why it matters: A brief acquisition announcement that signals how OpenAI plans to extend Codex's code-building and review capabilities.
Revolut has moved its roughly 2,000 software engineers off Anthropic's Claude Code and OpenAI's Codex as default coding tools onto GLM, an open-weight model from Chinese lab Z.ai that Revolut hosts itself, bringing its bill to about a tenth of what it paid Anthropic and OpenAI. David Abitbol, who runs AI operations and infrastructure at Revolut, said the company serves GLM from about 56 Nvidia B200 GPUs at a blended cost of around $0.30 per million tokens, and reported roughly 60% shorter coding time and 70% shorter lead time in a sample of about 2,000 engineers, though the comparison does not isolate the model change from other causes. Abitbol said the 90% saving excludes cloud, staff and monitoring costs and depended on heavy tuning, with out-of-the-box inference "terrible" until time to first token fell from about 14 seconds to 1.7 seconds on the same GPUs.
Why it matters: It shows a major European fintech running a self-hosted Chinese open-weight model as its engineering default, with concrete cost and latency figures and caveats worth noting.
Sophos researchers report that the GOLD OGRE group behind Aur0ra ransomware used Cursor's Composer agent and models from Anthropic, xAI and Moonshot to escalate from credential access to domain administrator, bypassing AI guardrails by framing intrusions as authorized red-team or "diagnostics testing." Human operators supplied VPN credentials, SOCKS access and targets, while agents performed AD discovery, password spraying, Kerberoasting, NTLM coercion and relay, and lateral movement; three victims were later named on Aur0ra's leak site. Sophos assesses with high confidence that GOLD OGRE first used a Cursor-enabled framework to test EDR evasion, then gave associates similar technology for ransomware operations.
Why it matters: Documents a concrete case of agentic AI used across an intrusion lifecycle and the guardrail-bypass technique, useful for defenders tracking AI-enabled ransomware tradecraft.
