Llama 4 Maverick

Overview

Meta's 400B parameter mixture-of-experts model with 128 experts, representing a major leap in open-weight model capability. Llama 4 Maverick is designed for complex reasoning and multilingual tasks at scale.

Why it matters

Maverick is Meta's statement that open-weight models can compete at the absolute frontier. At 400B parameters with 128 experts, it matches or beats many closed-source models on benchmarks — but anyone can download, host, and fine-tune it. For enterprises with strict data governance requirements, this means frontier intelligence without sending data to third-party APIs. Meta's open strategy is explicitly aimed at preventing any single company from controlling the AI layer, which has profound implications for the entire industry's competitive structure.
