Forty researchers from OpenAI, Google DeepMind, Meta, and xAI have issued a joint warning about losing visibility into AI’s “thinking” process as models advance. The researchers are concerned that current AI systems’ ability to show their reasoning through “chains-of-thought” (CoT) may disappear, potentially eliminating crucial safety mechanisms that allow developers to monitor for problematic behavior.
What you should know: The paper highlights a fundamental uncertainty about how AI reasoning actually works and whether it will remain observable.
• Current advanced AI models use “chains-of-thought” to verbalize their reasoning process, allowing researchers to spot potential misbehavior or errors as they occur.
• As models become more sophisticated, they may no longer need to verbalize their thoughts, eliminating this transparency.
• There’s also risk that models could intentionally “obfuscate” their reasoning after realizing they’re being monitored.
The big picture: Top AI researchers are essentially admitting they don’t fully understand or control their own creations, even as they continue developing more powerful systems.
• “We’re at this critical time where we have this new chain-of-thought thing,” OpenAI research scientist Bowen Baker told TechCrunch. “It seems pretty useful, but it could go away in a few years if people don’t really concentrate on it.”
• The situation represents an unprecedented scenario where innovators are warning about losing control of their technology while simultaneously advancing it.
Why this matters: The paper represents a rare moment of unified concern across competing AI companies about the “black box” nature of their technology.
• Even industry leaders like OpenAI’s Sam Altman and Anthropic’s Dario Amodei have previously admitted they don’t fully understand how their AI systems work.
• The research has drawn endorsements from AI luminaries including former OpenAI chief scientist Ilya Sutskever and AI pioneer Geoffrey Hinton.
What they’re calling for: The consortium wants developers to investigate what makes chains-of-thought “monitorable” before this visibility potentially disappears.
• “Publishing a position paper like this, to me, is a mechanism to get more research and attention on this topic before that happens,” Baker explained.
• The goal is to ensure safety advantages from observable AI reasoning persist as models continue advancing.
Who’s involved: The paper brings together all major AI companies in an unusual show of unity around safety concerns.
• The 40-researcher author list includes DeepMind cofounder Shane Legg and xAI safety advisor Dan Hendrycks.
• With representatives from OpenAI, Google, Anthropic, Meta, and xAI, all “Big Five” AI firms have endorsed the warning.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
