Open source AI models are increasingly winning out over closed systems like GPT-4 in the enterprise. This is what Matt Marshall reports for VentureBeat after numerous conversations with executives. The open models, such as Metas Llama, have now reached comparable quality and offer enterprises more control, customization, and cost efficiency. Major technology vendors such as Salesforce, Oracle, and SAP have integrated open source models into their enterprise applications. Meta’s open source models alone have been downloaded more than 400 million times – ten times more than last year. Well-known companies such as AT&T, Goldman Sachs and IBM are already successfully using these open systems. The main benefits cited are better control over security and privacy, and the ability to customize.
