    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.

    INDEX 14393
    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.

    INDEX 45
    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.

    INDEX 42
    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.

    INDEX 40
    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.

    The conjunction "and" appearing between two adjectives, adverbs, or descriptive phrases that together characterize or modify a noun or concept. This pattern shows "and" functioning as a coordinating connector between parallel descriptive elements in a series, particularly in contexts emphasizing compound qualities or paired characteristics.

    These examples contain fragments of words with selected syllables or morphemes marked, representing partial morphological units that appear within larger words across diverse technical and non-technical contexts (such as "libuv" from libraries, "NSU" from code, "edu" from place names, medical terms, and legal documents). The pattern reflects mid-word substrings that don't consistently correspond to meaningful linguistic boundaries, suggesting the selection marks text segments that may be important for tokenization, morphological analysis, or language model behavior at the subword level.

    The phrase "so far" or "thus far" appearing in academic, technical, or formal writing contexts, often indicating a temporal boundary or limitation on progress, findings, or achievements up to the present moment. The word "to" appears in the phrase "to date" serving a similar function of indicating temporal scope up to the present.

    The marked tokens represent function words and prepositions (such as "from," "to," "of," "for," "and," "in") that connect phrases and clauses within sentences, along with occasional adjectives modifying nouns related to agriculture and farming. These tokens function as grammatical connectors that structure sentences involving agricultural topics, government programs, institutional relationships, and technical descriptions.

    INDEX 21
    The marked tokens appear to be fragments of words that have been split across delimiters, often appearing within proper nouns, technical terms, or compound words in diverse academic and technical texts. The patterns suggest these are either OCR/text encoding artifacts, reference citations within brackets, or deliberate word segmentation where parts of a single word are delimited separately from their surrounding context.
