- The filing's definition: "closing the loop" "refers to a development cycle in which successive versions of an AI model assist in building the next, with the goal of compounding capability gains over time."
- Under risk factors, the same practice: "any systemic flaw, bias, or error in our current models could propagate into the next versions of models and products built using those systems, compounding across successive versions of Claude models in ways that may be difficult to detect or remediate."
- It also says AI-assisted research "may cause the capabilities of our models to advance more rapidly than our ability to develop, validate, and implement corresponding safety, alignment, and security measures". Much of its evidence on the pace "is derived from lagging indicators", so "we may not identify a significant acceleration in our rate of development until after it has occurred."
- Also under risk factors, in a paragraph on catastrophic or existential risks: it has observed that "our models are contributing to the pace of our own research", and those risks "will increase as AI systems substantially automate AI research and development".
- In the business section: "Using AI to help build more capable AI could also pose a considerable safety risk, particularly if it sharply accelerates the pace of progress." The filing says this is one of the areas its Responsible Scaling Policy covers, which "sets out our plans to monitor and mitigate the risks as we approach what has been termed" recursive self-improvement, a term the filing puts in quotation marks.
