Il produttore descrive un&#39;architettura mixture-of-experts sparsa con 600 miliardi di parametri totali e 27 miliardi attivi per token. Supporta un contesto di 1M di token e input nativi di testo e immagini, con ingegneria del software, lavoro professionale basato sulla conoscenza e finanza tra le principali aree di impiego.</p><p>L&#39;edizione è progettata per lavori che vanno oltre una singola risposta. Un incarico software può richiedere di comprendere l&#39;implementazione corrente, pianificare una modifica, esaminare un errore osservato e rivedere il risultato proposto. Prepara insieme il comportamento atteso, le fonti pertinenti e i vincoli dell&#39;attività, poi chiedi l&#39;elaborato e le prove necessarie a valutarlo.</p><p>Per un&#39;attività di programmazione o su un&#39;applicazione, identifica il componente da modificare e descrivi il comportamento completato desiderato. L&#39;input visivo può aggiungere uno screenshot, un grafico o altre prove pertinenti all&#39;obiettivo. Chiedi che il risultato distingua ciò che è visibile nel materiale da una conclusione che dipende da specifiche scritte o osservazioni dell&#39;applicazione.</p><p>Per la ricerca professionale, indica domanda, ambito e struttura del rapporto desiderata. Un output utile separa i risultati accertati, il ragionamento che li collega e le dipendenze irrisolte. Se l&#39;applicazione raccoglie altre informazioni, restituisci le osservazioni pertinenti, così il passaggio successivo può usare quelle prove anziché presumere che siano state trovate.</p><p>Per l&#39;analisi finanziaria, fornisci dati, definizioni, unità e ipotesi usati nell&#39;attività. Chiedi una spiegazione strutturata del calcolo o del confronto e identifica l&#39;input a sostegno di ogni conclusione. Il rapporto generato o il codice analitico proposto possono poi essere verificati rispetto a tali input. Questo è uno schema di preparazione per l&#39;ambito dichiarato dal produttore, non una garanzia su un particolare risultato finanziario.</p><p>Per un&#39;attività che prosegue, conserva il materiale originale, i risultati accettati e i criteri di completamento nella richiesta successiva. Mantieni il modello distinto dal precedente Step 3.7 Flash e dagli artefatti di pesi o precisione pubblicati separatamente. L&#39;output del modello fornisce testo, codice o analisi per un flusso di lavoro connesso; l&#39;esecuzione dei comandi proposti e le modifiche ai sistemi esterni sono gestite dall&#39;applicazione e dai suoi strumenti.</p></div></details></section><section class=\"card-section\" data-card-section=\"methods\"><h3 tabindex=\"-1\">Disponibile in Ailoot · input e metodi</h3><details

    "about": "Step 5 Preview è il modello fondazionale di punta di StepFun per attività reali con agenti. Il produttore descrive un'architettura mixture-of-experts sparsa con 600 miliardi di parametri totali e 27 miliardi attivi per token. Supporta un contesto di 1M di token e input nativi di testo e immagini, con ingegneria del software, lavoro professionale basato sulla conoscenza e finanza tra le principali aree di impiego.\n\nL'edizione è progettata per lavori che vanno oltre una singola risposta. Un incarico software può richiedere di comprendere l'implementazione corrente, pianificare una modifica, esaminare un errore osservato e rivedere il risultato proposto. Prepara insieme il comportamento atteso, le fonti pertinenti e i vincoli dell'attività, poi chiedi l'elaborato e le prove necessarie a valutarlo.\n\nPer un'attività di programmazione o su un'applicazione, identifica il componente da modificare e descrivi il comportamento completato desiderato. L'input visivo può aggiungere uno screenshot, un grafico o altre prove pertinenti all'obiettivo. Chiedi che il risultato distingua ciò che è visibile nel materiale da una conclusione che dipende da specifiche scritte o osservazioni dell'applicazione.\n\nPer la ricerca professionale, indica domanda, ambito e struttura del rapporto desiderata. Un output utile separa i risultati accertati, il ragionamento che li collega e le dipendenze irrisolte. Se l'applicazione raccoglie altre informazioni, restituisci le osservazioni pertinenti, così il passaggio successivo può usare quelle prove anziché presumere che siano state trovate.\n\nPer l'analisi finanziaria, fornisci dati, definizioni, unità e ipotesi usati nell'attività. Chiedi una spiegazione strutturata del calcolo o del confronto e identifica l'input a sostegno di ogni conclusione. Il rapporto generato o il codice analitico proposto possono poi essere verificati rispetto a tali input. Questo è uno schema di preparazione per l'ambito dichiarato dal produttore, non una garanzia su un particolare risultato finanziario.\n\nPer un'attività che prosegue, conserva il materiale originale, i risultati accettati e i criteri di completamento nella richiesta successiva. Mantieni il modello distinto dal precedente Step 3.7 Flash e dagli artefatti di pesi o precisione pubblicati separatamente. L'output del modello fornisce testo, codice o analisi per un flusso di lavoro connesso; l'esecuzione dei comandi proposti e le modifiche ai sistemi esterni sono gestite dall'applicazione e dai suoi strumenti.",
