What is Llama harness?
Llama harness is a conceptual framework and infrastructure developed by various entities that enables developers and organizations to utilize Meta AI's Llama models for building functional AI agents. It equips large language models with capabilities such as tool integration, memory management, and safety protocols. The underlying Llama models, developed by Meta AI, include versions like Llama 3 and Llama 4, which feature architectural shifts to mixture-of-experts (MoE) design and native multimodal capabilities. For instance, Llama 4 Scout operates with 17 billion active parameters across 16 experts and a 10-million-token context, while Llama 4 Maverick utilizes 17 billion active parameters across 128 experts with 400 billion total parameters. These models are classified as general-purpose AI models under the EU AI Act, requiring providers to fulfill obligations such as providing information on model architectures and training methods, and publishing a summary of training content. The Llama API, available in limited preview, facilitates programmatic access to these models.
