L'azienda Google ha annunciato la pubblicazione di un grande modello di linguaggio per il machine learning, Gemma, costruito utilizzando tecnologie impiegate per sviluppare il modello del chatbot Gemini, intento a competere con ChatGPT. Il modello \u00e8 disponibile in quattro varianti, coprendo 2 e 7 miliardi di parametri, in versioni base e ottimizzate per i sistemi di dialogo. Le varianti con 2 miliardi di parametri sono adatte per l'uso in applicazioni per consumatori e possono essere elaborate utilizzando solo CPU. Le varianti con 7 miliardi di parametri richiedono hardware pi\u00f9 potente e la presenza di GPU o TPU. <\/p>\n

Tra i campi di applicazione del modello Gemma si citano la creazione di sistemi di dialogo e assistenti virtuali, generazione di testi, formulazione di risposte a domande poste in linguaggio naturale, sintesi e riassunto di contenuti, spiegazione del significato di concetti e termini, correzione di errori nel testo, aiuto nell'apprendimento delle lingue. \u00c8 supportata la creazione di vari tipi di dati testuali, inclusi poesie, codice in linguaggi di programmazione, riscrittura di opere con parole diverse, e formulazione di lettere seguendo un template. Inoltre, il modello ha dimensioni relativamente contenute, permettendo l'uso su hardware personale con risorse limitate, ad esempio su normali laptop e PC. <\/p>\n

La licenza sul modello consente l'uso e la distribuzione gratuiti non solo in progetti di ricerca e personali, ma anche in prodotti commerciali. \u00c8 inoltre consentita la creazione e pubblicazione di varianti modificate del modello. Tuttavia, le condizioni d'uso vietano di impiegare il modello per compiere azioni dannose e prescrivono di utilizzare, per quanto possibile, la versione pi\u00f9 aggiornata di Gemma nei propri prodotti. <\/p>\n

Il supporto per lavorare con i modelli Gemma \u00e8 gi\u00e0 stato aggiunto agli strumenti di Transformers e al Responsible Generative AI Toolkit. Per ottimizzare il modello, \u00e8 possibile utilizzare il framework Keras e i backend per TensorFlow, JAX e PyTorch. \u00c8 anche garantita la possibilit\u00e0 di usare Gemma con i framework MaxText, NVIDIA NeMo e TensorRT-LLM. <\/p>\n

La dimensione del contesto considerato dal modello Gemma \u00e8 di 8.000 token (il numero di token che il modello pu\u00f2 elaborare e memorizzare durante la generazione del testo). A titolo di confronto, la dimensione del contesto dei modelli Gemini e GPT-4 \u00e8 di 32.000 token, mentre il modello GPT-4 Turbo supporta fino a 128.000 token. Il modello supporta solo la lingua inglese. In termini di prestazioni, il modello Gemma-7B \u00e8 leggermente inferiore al modello LLama 2 70B Chat e leggermente superiore ai modelli DeciLM-7B, PHI-2 (2.7B) e Mistral-7B-v0.1. Rispetto a Google, il modello Gemma-7B \u00e8 leggermente superiore a LLama 2 7B\/13B e Mistral-7B.
