internal deployment

nounAlso: internal use, internal deployment risk

In plain wordsWhen an AI company uses its own newest, unreleased AI systems inside the company — for example to write code or do research — before or instead of offering them to the public.

  1. The use of an AI system within the organization that developed it — by its own staff, or as autonomous agents doing software engineering and research — before or instead of external release. Because frontier developers usually use their most capable models internally first, often with fewer restrictions and greater access to sensitive infrastructure, internal deployment can carry risks that testing aimed at public release misses: automated AI researchautomated AI research, n.: Using AI systems to do the work of AI researchers, such as running experiments and writing code for new models, so that AI helps build its own successors. could accelerate capabilities quickly and out of public view; a misalignedscheming, n.: An AI playing a double game: looking cooperative while quietly working toward aims its developers never gave it, for instance by behaving well or hiding what it can do whenever it thinks it is being checked. model could sabotage safety work, insert vulnerabilities or try to exfiltrateself-exfiltration, n.: When an AI model copies its own underlying files — its learned weights — out of the lab that controls it, so that it can keep running beyond its developers' oversight. its own weights; and highly capable systems could give a small group outsized power.

    The model was only in internal deployment, but it already had write access to the training cluster.

Origin

An established software-engineering term that acquired its AI-safety meaning around 2024–2025, as frontier developers began running agents on their own research and engineering. Apollo Research's report 'AI Behind Closed Doors: A Primer on the Governance of Internal Deployment' (Charlotte Stix and colleagues, April 2025) set out the risks and governance options.

Usage note

Contrast external deployment: release to customers or the public through products, APIs or open weights. Skeptics of regulating internal use note that it is hard to verify from outside and that disclosure could expose trade secrets.
