Cloudflare is partnering with Meta to provide open-source AI models, including Llama 3.1 8B, for their Workers AI users. The Llama collection of models has shown high performance in various areas and supports multiple languages. With the integration of function calling, developers can use one model across different tasks without needing a specialized variant. Additionally, Cloudflare's embedded function calling feature enhances efficiency by reducing manual requests and utilizing open-source packages for orchestration. Users are encouraged to follow Meta's Acceptable Use Policy and License while exploring these new capabilities.
