Il passaggio chiave \u00e8 la migrazione da Python a Rust, scelta che ha gi\u00e0 portato il nuovo sistema a gestire <strong>il 95% delle richieste di produzione<\/strong> con un netto salto di efficienza.<\/p><p>I numeri aiutano a capire la scala del progetto: Habitat supera i <strong>70 milioni di richieste al secondo<\/strong>, serve oltre 1 miliardo di utenti ogni settimana e gestisce pi\u00f9 di 500 PB di dati. In questo contesto, ridurre consumo di CPU, memoria e latenza non \u00e8 solo un miglioramento tecnico, ma un passaggio necessario per sostenere la crescita della piattaforma.<\/p>\n  <\/div><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\/09\/openai-porta-habitat-da-python-a-rust-1d4ba8d7-6012-4d18-955e-7401-1p8knova22.webp\" 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\/09\/openai-porta-habitat-da-python-a-rust-1d4ba8d7-6012-4d18-955e-7401-1p8knova22.webp\" alt=\"OpenAI \u5c06 Habitat \u4ece Python \u8fc1\u79fb\u81f3 Rust\uff1aCPU \u6548\u7387\u63d0\u5347 6 \u500d\uff0c\u670d\u52a1 10 \u4ebf ChatGPT \u7528\u6237\" loading=\"lazy\" style=\"display:block;max-width:100%;height:auto;margin:0 auto;pointer-events:auto\"><\/a><\/figure>\n  \n\n      <section class=\"fbp5-section\">\n        \n        <h2>Habitat \u00e8 diventato un servizio centrale per <span>l\u2019infrastruttura OpenAI<\/span><\/h2>\n        <p>Habitat era nato come libreria Python che dialogava con Azure Cosmos DB e permetteva ai team prodotto di leggere e scrivere dati senza dover gestire direttamente il database. Nel tempo si \u00e8 evoluto in un sistema di storage distribuito capace di occuparsi di identificazione dei tipi di dato, instradamento delle richieste, autorizzazioni, cifratura, serializzazione e gestione del pool di connessioni.<\/p><p>Con l\u2019aumento del numero di prodotti e del volume dei dati, il modello basato su libreria condivisa ha per\u00f2 mostrato limiti pratici. Ogni modifica richiedeva il coordinamento del deploy su decine di servizi, con maggiore complessit\u00e0 operativa e pi\u00f9 rischio di errori. Per questo OpenAI ha trasformato Habitat in un servizio indipendente, cos\u00ec da centralizzare aggiornamenti, monitoraggio e funzioni di piattaforma.<\/p><p>Questa scelta porta anche vantaggi sul fronte della sicurezza. Un punto di controllo unico consente di applicare in modo pi\u00f9 coerente policy di accesso, log di audit e permessi sulle risorse di storage, riducendo il rischio di accessi non autorizzati ai dati degli utenti da parte di componenti esterni, interni o intermediari software.<\/p>\n        \n        \n        \n        \n        \n      <\/section>\n    \n\n      <section class=\"fbp5-section\">\n        \n        <h2>Perch\u00e9 OpenAI ha lasciato Python e quali risultati ha <span>ottenuto con Rust<\/span><\/h2>\n        <p>OpenAI aveva inizialmente scelto Python per privilegiare stabilit\u00e0 e velocit\u00e0 di sviluppo, ma nei carichi ad alta concorrenza sono emersi i classici limiti del linguaggio in termini di overhead CPU, consumo di memoria e latenza di rete, soprattutto nelle code pi\u00f9 lente delle richieste.<\/p><p>Un intervento interessante ha riguardato anche il riuso delle connessioni. Il comportamento predefinito del client aiohttp seguiva una logica LIFO, ci\u00f2\u00e8 ultimo entrato primo uscito, che poteva finire per concentrare il traffico sugli stessi processi pi\u00f9 lenti. Passando a una logica FIFO, quindi primo entrato primo uscito, OpenAI ha migliorato la distribuzione del carico.<\/p><p>La svolta vera \u00e8 arrivata nel secondo trimestre del 2026, quando Habitat \u00e8 stato riscritto completamente in Rust da due ingegneri con il supporto di Codex e GPT-5.5. I dati condivisi parlano di <strong>efficienza CPU migliorata di 6 volte<\/strong> e di <strong>efficienza della memoria migliorata di 15 volte<\/strong>, insieme a una riduzione sia della latenza media sia di quella di coda.<\/p>\n        \n        \n        \n        \n        \n      <\/section>\n    \n\n      <section class=\"fbp5-section\">\n        \n        <h2>Un\u2019architettura pi\u00f9 controllata anche per query e <span>analisi dei dati<\/span><\/h2>\n        <p>Habitat espone inoltre un\u2019API NoSQL volutamente limitata, cos\u00ec da impedire ai client di eseguire query SQL non controllate, join complesse o scansioni estese dei dati. Per gli scenari che richiedono interrogazioni pi\u00f9 sofisticate, OpenAI usa il rilevamento delle modifiche ai dati per sincronizzare in tempo reale o quasi reale le informazioni verso Rockset, piattaforma destinata ad analisi offline e ricerca.<\/p><p>Il quadro che emerge \u00e8 quello di un\u2019infrastruttura costruita per tenere insieme scala, affidabilit\u00e0 e controllo operativo. OpenAI ha gi\u00e0 anticipato che torner\u00e0 sull\u2019argomento con approfondimenti dedicati all\u2019espansione del livello di storage su Azure Cosmos DB e all\u2019ottimizzazione
