Meta Releases Llama 4: Open Source AI Closes Gap with Frontier Models

Meta AI released Llama 4, its fourth-generation open-source language model family. The flagship Llama 4 405B achieves GPT-4o-level performance on most benchmarks while remaining fully open for commercial use. The smaller Llama 4 Scout (17B) and Maven (109B) models deliver exceptional quality for their size. Enterprise adoption is accelerating as organizations prefer open-source models for data privacy, cost control, and customization. Llama 4 is available on Hugging Face and major cloud providers.
