    Description
    Eleuther's "Default" Explainer, which shows the auto-interp model a sample from activating texts (with max activations highlighted) and asks the model to think through possible patterns, and then provide the explanation. This is an alternate version that doesn't use quantiles.

    The highlighted tokens represent partial words or word fragments that appear within larger words. These fragments are typically 2-4 characters long and occur mid-word across diverse contexts including plant species names (Pistacia), proper nouns (Kishwaukee, Sisk), technical terms (pistol, memristance), and informal language (pis). The pattern suggests identification of morphologically interesting substrings or phonetic components embedded within words across different text domains.

    The marked tokens appear in technical and scientific documentation across diverse domains (software licenses, source code, academic papers, HTML/web content). The marked tokens represent various linguistic elements: common noun phrases ("KIND"), URL protocol prefixes ("://"), LaTeX commands and symbols ("begin", "!"), HTML entities ("amp", "lementary"), and mathematical notation markers ("!"). These are content-specific tokens that serve structural or semantic purposes within their respective contexts rather than expressing a single unified pattern.

    The highlighted tokens appear in healthcare and procedural contexts, marking phrases related to obtaining or receiving medical services, undergoing treatments, or attending appointments. They serve as connectors or action verbs that bridge the subject with a medical intervention or visit.

    The phrase "behind" (or "behind the") appears consistently across examples to convey the meaning of something occurring out of public view, in private, or not visible to observers. This includes idiomatic uses like "behind closed doors" (private interrogation or decision-making), "behind the scenes" (hidden processes or preparation work), and literal spatial uses like "behind the counter" or "behind the wheel" (positioned at a location). The pattern reflects how "behind" functions as a preposition denoting concealment, privacy, or a position not immediately apparent to an audience.

    The marked phrases represent adjectives or adjectival phrases used to describe modifications, enhancements, or distinctive qualities added to nouns. These phrases typically convey customization, personalization, or refinement—such as "with a twist," "a fresh spin," "added sophistication," "an extra layer," or "a welcome shot." The pattern demonstrates how descriptive language emphasizes the value-addition or improvement of the preceding noun, creating emphasis on uniqueness, style, or enhancement.

    The marked tokens represent electrical and technical specifications, particularly numerical values and units (voltage measurements like "5 volt," "1 Volt," "0.7 v," "220V," "100 mV") and action phrases describing the application or control of voltage ("applied," "is applied," "applying a dc voltage," "voltage is applied"). These appear in technical and scientific documentation where precise electrical parameters and their operational context are being described.

    The word "trend" (and related forms like "trending," "trends," "trend-setting," "trend-driven," "trend-line") appears in academic and technical contexts across scientific papers, reports, and professional writing. The term is used to describe general patterns, directions of change, or prevailing tendencies in data analysis, fashion, social behavior, research collaboration, and material science. The marked instances occur as standalone nouns or as components of compound adjectives, consistently referring to observable directional patterns or contemporary movements in their respective domains.

    The marked tokens represent contractions where an apostrophe is elided or appears in contexts where it marks the abbreviated form of "not" or possessive pronouns (e.g., "hadn't," "didn't," "I'm," "shouldn't," "wasn't"). These represent standard English contraction patterns in narrative and conversational text.

    The marked tokens represent short phrases, clauses, and single words that serve as logical break points in narrative flow—typically at sentence boundaries, clause transitions, or between independent thoughts. These include period punctuation, conjunctions, prepositions introducing new clauses, and noun phrases that mark shifts in time, location, or topic within casual blog-style prose and personal narratives.

    The marked tokens are adjectives or modifiers that precede nouns to describe qualities or characteristics. These words typically function as descriptive attributes that specify or enhance the meaning of the noun that follows, appearing in formal and technical contexts across medical, legal, and scientific writing.

    The marked tokens represent short phrasal or conjunctive elements that connect ideas or provide alternatives within sentences. These include coordinating conjunctions (or, and), prepositions (with, by), and short phrases that express combination, modification, or alternative possibilities (a hybrid, a synergistic, a linear, their cooperation). They function as cohesive bridges between clauses or noun phrases, often indicating multiple options, concurrent actions, or compositional relationships in technical, descriptive, and expository writing.

    Small function words and punctuation marks are marked as important across product descriptions, technical specifications, and informational texts. These include articles (the, a), prepositions (of, in, for), conjunctions (and, or), commas, and parentheses that structure lists and clarifications. The pattern suggests these tokens are significant for parsing compound noun phrases, feature enumerations, and technical specifications where grammatical connectors organize product attributes and comparisons.
