Meta's ambitious Llama 4 Behemoth, a 2-trillion parameter Mixture-of-Experts (MoE) model, has encountered a significant delay. Originally announced in April 2025 as a frontier 'teacher model' meant to redefine AI capabilities, the model remains unreleased and officially 'in training' as of April 23, 2026—a full year behind schedule.
This protracted development has allowed competitors to seize the initiative. Models like Gemini 2.5 Pro, Claude Opus 4.7, GPT-5.4, and Kimi K2.6 have already launched, filling the market gap Llama 4 was intended to dominate. The delay raises serious questions about Llama 4's eventual competitive edge and its impact on Meta's broader AI strategy.
