Meta's 'Avocado' Frontier Model Delayed Again as Llama 4 Behemoth Struggles; Scout's 10M Token Context Stands Out

Meta's next flagship frontier model, codenamed 'Avocado,' missed its expected March 2026 launch after engineers struggled to improve capabilities, mirroring ongoing delays with the Llama 4 Behemoth teacher model. Despite these setbacks, Meta's Llama 4 Scout — featuring an impressive 10-million-token context window — remains a notable capability in the open-model landscape, with the full Llama 4 family (Scout, Maverick, Behemoth) trained on multimodal text, image, and video data. No new Llama model releases were published during the April 2–5, 2026 window, suggesting Meta is in a consolidation phase ahead of a potential next-generation release.
