Osmosing
/ˈɒz.moʊ.zɪŋ/ (the 's' is technically a 'z'; the distinction matters to linguists and to no one else)gerund of disputed originExperimental
Etymology
From Greek osmos (a pushing, a thrust) + -ing; the verbal form osmosing was coined by a technical writer at Anthropic who needed a present participle for a loading state and has since appeared in fourteen peer-reviewed papers without anyone questioning it
Definition
The passive absorption of contextual information from the user's prompt through the semi-permeable membrane of Claude's attention mechanism, requiring no active retrieval effort and producing a net movement of meaning from high-concentration regions (the user's intent) to low-concentration regions (the model's prior beliefs). The model does nothing; information simply flows in.

"Osmosing was identified as the dominant intake modality in short-context tasks, with the model reportedly absorbing the full user specification 'without really trying,' per one engineer's postmortem annotation." - Platform Engineering Review Q2 2024
