LLaMA
Large Language Model Meta AI, is Meta’s family of open‑weight large language models first released in 2023 as a research‑focused alternative to proprietary systems. Designed for flexibility, LLaMA models come in multiple sizes from lightweight versions for local or edge deployment to massive multi‑hundred‑billion‑parameter variants for advanced reasoning and generation. Over successive releases, Meta has expanded capabilities with longer context windows, improved efficiency through Mixture‑of‑Experts architectures, and native multimodality that can process both text and images. The open‑weight licensing allows researchers, startups, and enterprises to fine‑tune and self‑host models, enabling privacy‑preserving and cost‑efficient AI development. By 2025, LLaMA had evolved into a competitive, community‑driven ecosystem powering applications from chat assistants to large‑scale knowledge systems.
