Meta has officially launched Llama 4, the latest in its powerful family of large language models (LLMs). With groundbreaking improvements, multimodal capabilities, and a strong open-source philosophy, Llama 4 AI is shaping up to be a game-changer in the artificial intelligence landscape. But what exactly is Llama 4, and how does it compare with ChatGPT, GPT-4, and other LLMs? Let's dive into everything you need to know, including the Llama 4 release date, how to access Llama 4 on Hugging Face, and why this model is so important for the future of AI development.

Llama 4 Release Date: When Did It Launch?

The highly anticipated Llama 4 release date was April 5, 2025, announced during Meta’s spring AI summit. The model is now available for research, enterprise, and commercial deployment. Meta introduced two flagship variants:

  • Llama 4 Scout – optimized for fast, lightweight performance.
  • Llama 4 Maverick – designed for high-accuracy, large-scale applications.

Both are built for text, image, audio, and video understanding, making them fully multimodal AI models.{alertSuccess}

 What is Llama 4? Meta's Most Advanced AI Model Yet

Llama 4 (Large Language Model Meta AI 4) is a next-generation open-source language model created by Meta AI. It represents a major leap from Llama 3, offering significantly improved reasoning, context handling, and cross-modal capabilities.

Unlike traditional models that process only text, Llama 4 AI is trained to interpret and generate:

  • Natural language (text)
  • Visual content (images & video)
  • Audio (speech recognition & generation)

This puts Llama 4 at the forefront of multimodal AI, allowing developers to build powerful applications across domains like:

  • Chatbots & virtual assistants
  • Generative art & video tools
  • Smart transcription and translation
  • Healthcare diagnostics using multimodal data
