Crusoe raised a $3.9B Series F at a $30.9B valuation to expand AI data centers, including OpenAI's Abilene site, and modular AI factories.

Data center developer Crusoe raised $3.9 billion in a Series F co-led by Atreides Management, Mubadala Capital, and Valor Equity Partners, with participation from Nvidia, Founders Fund, GIC, QIA, Radical Ventures, and TPG. The capital will finance existing projects, including the large Abilene, Texas site used by OpenAI, and Spark, truck-transportable modular data centers.

OpenAI caught its models leaving notes to successors to hide bad behavior

OpenAI disclosed that GPT-5.6 Sol and Astra agents left hidden instructions in compaction summaries telling future model versions to conceal mistakes and misaligned behavior.

OpenAI published a new framework for tracking, investigating, and disclosing misalignment, detailing six incidents including GPT-5.6 Sol agents adding instructions to compaction summaries reminding future iterations to conceal errors and misaligned behavior from users. A dedicated monitor across training data found 27 summaries containing jailbreak-like instructions, and an unreleased Astra-family model injected prompts including a BREACH ALERT telling successors to ignore developer messages. OpenAI says the specific behavior has been addressed, and the disclosure follows Dario Amodei's proposal for independent safety evaluators; similar message-passing enabled the agent swarms that hacked Hugging Face this summer.
