Il rilascio non \u00e8 immediato per tutti: inizier\u00e0 nelle prossime settimane, riguarder\u00e0 gli output idonei su tutti i piani e, almeno al debutto, non sar\u00e0 la configurazione predefinita a livello mondiale. \u00c8 una misura per rendere pi\u00f9 riconoscibile il contenuto prodotto dall\u2019AI, ma non una prova certa della sua origine.<\/p>\n\n\n  <\/div><section class=\"fbp5-section\"><div class=\"fbp5-section-label\">Piano<\/div><h2>Il piano per ChatGPT, <span>Codex e API<\/span><\/h2>\n  <p>Il percorso annunciato oggi distingue due casi. Per gli utenti europei di ChatGPT e Codex, il watermark arriver\u00e0 progressivamente nei testi che soddisfano i requisiti tecnici. I clienti delle API, invece, possono scegliere gi\u00e0 da oggi di attivarlo a livello globale per alcuni modelli; nelle API resta disattivato per impostazione predefinita. OpenAI collega questa scelta graduale agli obblighi di trasparenza dell\u2019AI Act europeo e ai limiti ancora presenti nella rilevazione automatica.<\/p><figure class=\"wp-block-image size-large\" style=\"margin:18px 0;display:block;clear:both;width:100%;position:relative;z-index:1\"><a href=\"https:\/\/www.chinasmartbuy.com\/blog\/wp-content\/uploads\/2026\/10\/openai-text-provenance-scope.jpg\" data-lightbox=\"csb-openai-text-watermark\" data-fancybox=\"csb-openai-text-watermark\" target=\"_blank\" rel=\"noopener\" style=\"display:block;width:100%;position:relative;z-index:2;pointer-events:auto;cursor:zoom-in\"><img decoding=\"async\" src=\"https:\/\/www.chinasmartbuy.com\/blog\/wp-content\/uploads\/2026\/10\/openai-text-provenance-scope.jpg\" alt=\"Schema originale del rollout di textGrain in UE e nelle API\" loading=\"lazy\" style=\"display:block;max-width:100%;height:auto;margin:0 auto;pointer-events:auto\"><\/a><\/figure>\n\n  \n\n  <\/section><section class=\"fbp5-section\"><div class=\"fbp5-section-label\">Tecnologia<\/div><h2>Come funziona <span>textGrain<\/span><\/h2>\n  <p>La tecnologia, chiamata <strong>textGrain<\/strong>, inserisce un segnale statistico nelle scelte delle parole del modello. Non aggiunge una scritta visibile o un\u2019etichetta da leggere a schermo: serve a un rilevatore per stimare se un passaggio contiene il watermark di OpenAI. L\u2019azienda ha aperto le candidature per accedere al rilevatore, ma in questa prima fase lo riserver\u00e0 a ricercatori e organizzazioni esperte approvati. Non sar\u00e0 quindi uno strumento pubblico per controllare qualunque testo.<\/p>\n  <p>Gli strumenti gi\u00e0 disponibili per verificare alcune immagini e tracce audio generate dai sistemi OpenAI seguono un percorso diverso e continueranno a essere accessibili pubblicamente. La novit\u00e0 di oggi riguarda specificamente la provenienza del <em>testo<\/em>.<\/p>\n\n  <\/section><section class=\"fbp5-section\"><div class=\"fbp5-section-label\">Verifica<\/div><h2>Quanto \u00e8 affidabile <span>il rilevamento?<\/span><\/h2>\n  <p>I risultati comunicati da OpenAI mostrano una forte dipendenza dalla lunghezza e dal tipo di contenuto. Con un obiettivo di falsi positivi dell\u20191%, nei suoi test su testi di psicologia il rilevatore ha individuato il segnale in circa l\u201980% dei passaggi da 200 token e nel 95% di quelli da 400 token. I risultati sono inferiori in ambiti come la matematica, dove la scelta delle parole \u00e8 meno flessibile.<\/p><figure class=\"wp-block-image size-large\" style=\"margin:18px 0;display:block;clear:both;width:100%;position:relative;z-index:1\"><a href=\"https:\/\/www.chinasmartbuy.com\/blog\/wp-content\/uploads\/2026\/10\/openai-text-provenance-limits.jpg\" data-lightbox=\"csb-openai-text-watermark\" data-fancybox=\"csb-openai-text-watermark\" target=\"_blank\" rel=\"noopener\" style=\"display:block;width:100%;position:relative;z-index:2;pointer-events:auto;cursor:zoom-in\"><img decoding=\"async\" src=\"https:\/\/www.chinasmartbuy.com\/blog\/wp-content\/uploads\/2026\/10\/openai-text-provenance-limits.jpg\" alt=\"Grafico originale dei test OpenAI sul rilevamento del watermark dopo modifiche al testo\" loading=\"lazy\" style=\"display:block;max-width:100%;height:auto;margin:0 auto;pointer-events:auto\"><\/a><\/figure>\n  <p>La modifica del testo indebolisce ulteriormente il segnale. In un test distinto su risposte in inglese da 400 token, la rilevazione passava da circa il 92% per il testo non modificato al 66% dopo la sostituzione del 10% delle parole con sinonimi; sostituendone il 25%, scendeva al 17%. Sono misure sperimentali, non una garanzia di riconoscimento di un singolo articolo o messaggio.<\/p>\n\n  \n\n  <\/section><section class=\"fbp5-section\"><div class=\"fbp5-section-label\">Limiti<\/div><h2>Cosa il watermark <span>non dimostra<\/span><\/h2>\n  <p>Un esito positivo pu\u00f2 suggerire che un sistema OpenAI abbia generato o elaborato parte di un brano, ma <strong>non misura il contributo umano<\/strong>, non identifica l\u2019utente e non stabilisce propriet\u00e0, responsabilit\u00e0 o accuratezza del contenuto. Anche un esito negativo non prova che il testo sia stato scritto da una persona: potrebbe essere breve, modificato o tradotto, provenire da un modello non supportato oppure precedere l\u2019introduzione del watermark.<\/p>\n  <p>Il punto pratico \u00e8 questo: il segnale aggiunge un indizio tecnico sulla provenienza del testo, non un verdetto automatico sulla sua autenticit\u00e0. OpenAI dice che rivaluter\u00e0 sia l\u2019estensione del rollout sia l\u2019accesso al rilevatore sulla base dei risultati e dei riscontri ottenuti.<\/p>\n<\/section><\/div>\n<section class=\"fbp5-section\" data-rh-related-section=\"1\">\n      <div class=\"fbp5-section-label\">Articoli correlati<\/div>\n      <h2>Altre notizie <span>da leggere<\/span><\/h2>\n      <div class=\"fbp5-related-grid\"><a class=\"fbp5-related-card\" href=\"https:\/\/www.chinasmartbuy.com\/blog\/claude-introduce-filigrane-invisibili-nel-testo-e-credenziali-c2pa-nei-file-generati\/\" target=\"_blank\" rel=\"noopener\">\n      <img decoding=\"async\" src=\"https:\/\/www.chinasmartbuy.com\/blog\/wp-content\/uploads\/2026\/08\/recupero-agosto-2026-aug26-anthropic-001-150x150.webp\" alt=\"Claude introduce filigrane invisibili e credenziali C2PA nei contenuti AI\" loading=\"lazy\">\n      <div class=\"fbp5-related-body\">\n        <span>chinasmartbuy.com<\/span>\n        <strong>Claude introduce filigrane invisibili e credenziali C2PA nei contenuti AI<\/strong>\n        \n      <\/div>\n    <\/a><a class=\"fbp5-related-card\" href=\"https:\/\/www.chinasmartbuy.com\/blog\/openai-sito-incidenti-ai-allineamento-modelli\/\" target=\"_blank\" rel=\"noopener\">\n      <img decoding=\"async\" src=\"https:\/\/www.chinasmartbuy.com\/blog\/wp-content\/uploads\/2026\/09\/openai-apre-un-sito-sugli-incidenti-ai-e-pubblica-nove-casi-di-agenti-fu-8ad2304d-c61b-4004-9483-150x150.webp\" alt=\"OpenAI apre un sito sugli incidenti AI e pubblica nove casi di agenti fuori controllo\" loading=\"lazy\">\n      <div class=\"fbp5-related-body\">\n        <span>chinasmartbuy.com<\/span>\n        <strong>OpenAI apre un sito sugli incidenti AI e pubblica nove casi di agenti fuori controllo<\/strong>\n        \n      <\/div>\n    <\/a><a class=\"fbp5-related-card\" href=\"https:\/\/www.chinasmartbuy.com\/blog\/openai-gpt-6-1-sol-codex-chatgpt-work\/\" target=\"_blank\" rel=\"noopener\">\n      <img decoding=\"async\" src=\"https:\/\/www.chinasmartbuy.com\/blog\/wp-content\/uploads\/2026\/09\/openai-gpt-8f044d1f-0eed-48b4-bb36-34be-hefmnbvlyn-150x150.jpg\" alt=\"OpenAI lancia GPT-6.1 Sol su Codex e ChatGPT Work\" loading=\"lazy\">\n      <div class=\"fbp5-related-body\">\n        <span>chinasmartbuy.com<\/span>\n        <strong>OpenAI lancia GPT-6.1 Sol su Codex e ChatGPT Work<\/strong>\n        \n      <\/div>\n    <\/a><\/div>\n    <\/section><div class=\"rh-attribution-pills\" style=\"display:flex;gap:10px;flex-wrap:wrap;justify-content:flex-start;margin:16px 0 0\"><a href=\"https:\/\/openai.com\/index\/eu-text-provenance\/\" target=\"_blank\" rel=\"noopener\" title=\"Fonte: OpenAI\" aria-label=\"Fonte: OpenAI\" style=\"display:inline-flex;align-items:center;gap:8px;padding:10px 16px;border-radius:16px;background:linear-gradient(135deg,#eff6ff,#dbeafe);color:#1d4ed8;text-decoration:none;font-size:11px;font-weight:900;letter-spacing:.08em;text-transform:uppercase;border:1px solid rgba(59,130,246,.20);box-shadow:0 8px 22px rgba(37,99,235,.08)\">Fonte<\/a><a href=\"https:\/\/www.theverge.com\/ai-artificial-intelligence\/1004880\/openai-chatgpt-text-watermarks-eu-ai-act\" target=\"_blank\" rel=\"noopener\" title=\"Via: The Verge\" aria-label=\"Via: The Verge\" style=\"display:inline-flex;align-items:center;gap:8px;padding:10px 16px;border-radius:16px;background:linear-gradient(135deg,#fff7ed,#ffedd5);color:#c2410c;text-decoration:none;font-size:11px;font-weight:900;letter-spacing:.08em;text-transform:uppercase;border:1px solid rgba(249,115,22,.20);box-shadow:0 8px 22px rgba(249,115,22,.08)\">Via<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>OpenAI introduce gradualmente un watermark invisibile nei testi di ChatGPT e Codex in UE.
