Meta’s internal coding assistant Metamate combines both OpenAI’s GPT-4 and Meta’s own Llama AI model to support developers, according to a report by Kali Hays in Fortune. The tool has been using GPT-4 since early 2024, despite CEO Mark Zuckerberg’s public promotion of Llama as a leading AI model. Current and former Meta employees, speaking anonymously, indicated that Metamate selects between Llama and GPT-4 depending on the specific query. The tool performs basic coding tasks effectively but struggles with complex engineering work. Additionally, the Chan Zuckerberg Initiative, Mark Zuckerberg’s philanthropic organization, is developing an educational AI tool using OpenAI’s technology and has appointed OpenAI CEO Sam Altman to its AI advisory board.
