Encodes companies, institutions, and collective entities.
What It Does
Identity.Organization neurons activate on references to collective entities that operate as unified agents in the world: companies (Apple, Toyota), governments and agencies (the European Union, the FDA), universities (MIT, the Sorbonne), non-profits, religious institutions, and other organized groups with distinct identities. They encode the organization as a coherent actor, not just a name-string.
How It Behaves
Organization neurons concentrate in the middle layers, where contextual disambiguation determines whether 'Apple' means the tech company or the fruit, and where pronoun resolution links 'they' back to the correct organizational entity. They co-activate frequently with Number.Money neurons (organizational financial references), Time neurons (founding dates, historical periods), and Relation.Reference neurons (linking pronouns back to organizations).
Research Example
In OLMo 3 7B, Identity.Organization neurons fire on 'the company announced' when tracking a tech company discussion, even when 'the company' contains no organization name — the coreference resolution that links the pronoun to the organization is partially handled by these neurons maintaining the entity's activation state across multiple sentences.
