Meta’s Mango model, an image and video generation system developed alongside the text-focused Avocado LLM under Chief AI Officer Alexandr Wang, was internally targeted for a first-half 2026 launch following its December 2025 reveal. Development has faced headwinds, including a March 2026 delay for Avocado after internal benchmarks showed it lagging rivals like Gemini 3.0 in reasoning and coding. An April 2026 report indicated plans to eventually open-source versions of these models from Meta’s Superintelligence Labs, though proprietary elements and safety reviews remain in play. Traders are watching for any official announcements, developer conferences, or earnings commentary that could clarify whether Mango meets the original H1 window or slips further amid competitive pressure from OpenAI, Google, and Anthropic.
