Meta Drops 405B Llama Bomb

Description

What a week for builders! Meta just dropped a seismic release: Llama 3.1, crowned by a monstrous 405B parameter model, the largest open-weight model to date. The community is buzzing, not just about its power, but about the very definition of 'open source,' as Meta's new license introduces restrictions for major tech players. This release isn't happening in a vacuum. It's part of a massive wave of innovation, with Meta also unveiling its native multimodal model, Chameleon, Cohere pushing multilingual boundaries with Aya 23, and Perplexity letting users create custom AI Personas. For developers, this translates to an unprecedented arsenal of specialized, powerful tools. The barrier to building sophisticated, multi-modal, and multi-lingual agents just got obliterated. It's time to build.
