Meta's New AI Models Avocado and Mango: First Releases Under Alexandr Wang
April 8, 2026 · 6 min read · Happycapy Guide
Meta is preparing to launch Avocado and Mango — its first AI models built under Alexandr Wang's Superintelligence unit. They will be partially open-source, with proprietary versions of the strongest capabilities kept closed. No release date confirmed yet. Claude and GPT-5.4 remain the production benchmarks to beat.
Axios broke news on April 6, 2026: Meta is preparing to release its first AI models under Alexandr Wang, the Scale AI founder who now runs Meta's AI division. The models are internally named Avocado and Mango. They represent the first output from Meta's Superintelligence unit — and a significant test of whether Wang can reverse Meta's underperforming AI track record.
Who Is Alexandr Wang and What Changed at Meta?
Alexandr Wang founded Scale AI, which became the dominant AI training data platform used by nearly every major lab — including OpenAI, Google DeepMind, and the US Department of Defense. Meta acquired Scale AI in early 2026, simultaneously installing Wang as head of AI to replace the leadership behind Meta's prior underperforming products.
Wang's arrival coincided with a personnel shift that drew criticism: multiple senior researchers reportedly left rather than work under new leadership, leading to r/LocalLLaMAcommentary that “nobody worth a damn stayed.” That context matters for evaluating Avocado and Mango — these models reflect Wang's team, not the researchers behind LLaMA 3 and earlier Meta frontier work.
Meta acquired Scale AI in early 2026, bringing Alexandr Wang in as head of AI. Scale AI was the dominant training data company used by every major lab.
Meta's LLaMA family was fully open-source. Avocado and Mango mark a strategic shift: partial open-source, with proprietary high-capability versions kept closed.
Meta simultaneously laid off 2,200 workers in 2026 while accelerating AI spending — a signal that it is restructuring around AI-driven efficiency, not headcount.
Open-source versions build developer ecosystem and goodwill. Proprietary versions are where Meta monetizes and retains competitive edge on frontier capabilities.
What Are Avocado and Mango?
Based on reporting from Axios and AI Daily, Avocado and Mango are distinct models in a new family — not just a new LLaMA version. Key confirmed details:
- First models from Meta's Superintelligence unit — a new division separate from the original FAIR research team
- Partial open-source strategy — versions of both models will be open-sourced after safety review; strongest proprietary versions will stay closed
- Consumer-facing AI product — designed to power Meta AI inside WhatsApp, Instagram, Facebook, and Ray-Ban smart glasses, not just developer APIs
- No benchmark results yet — no MMLU, GPQA, or Arena scores published at time of writing
Meta previously used plain versioned names (LLaMA 3, LLaMA 3.1). Using fruit codenames (Avocado, Mango) follows Google's Gemini family pattern and signals that these are distinct flagship models — not incremental updates to the existing architecture.
The Open-Source Shift: What It Means
Meta's LLaMA family was a genuine open-source contribution — weights fully downloadable, no restrictions on commercial use above a certain user threshold. That strategy built enormous developer goodwill and community adoption. The shift to partial open-source with Avocado and Mango signals that Meta is trying to monetize its AI frontier more directly — keeping the most capable model versions proprietary while releasing lighter open-source versions to maintain developer ecosystem.
This is the same playbook as Mistral (open weights for smaller models, API-only for frontier) and xAI (open Grok versions, closed API for full capability). The practical effect: the open-source Avocado/Mango releases will likely lag the proprietary versions by capability, similar to how LLaMA 3.1 70B lagged GPT-4 at launch.

What to Watch For at Launch
The models have not launched yet. When they do, these are the metrics that will determine whether the Wang-era Meta AI is a genuine frontier competitor or a repackaged also-ran:
- LMSYS Arena ranking— the community benchmark Meta's MAI-Image-2 already reached #3 in vision. Can Avocado/Mango crack top-3 in the text category?
- Context window — frontier models now compete at 1M+ tokens. What will Meta ship?
- Agentic capability — tool use, multi-step planning, and structured output quality are the battleground for 2026
- Open-source timeline — how long after proprietary launch before open weights are released?
Until launch data is available, claims about Avocado and Mango's capabilities are speculation. The honest assessment: Wang's access to Scale AI's training data infrastructure is a genuine competitive advantage. Whether the modeling talent retained at Meta can execute is the open question.

What are Meta's Avocado and Mango AI models?
Avocado and Mango are the codenames for the first AI models developed under Alexandr Wang, Meta's new AI chief and founder of Scale AI. They are the first output of Meta's Superintelligence unit and will be partially open-sourced after safety review.
Who is Alexandr Wang and why does he matter to Meta AI?
Alexandr Wang founded Scale AI, acquired by Meta in 2026. Zuckerberg put Wang in charge of Meta's AI research to replace underperforming leadership. Wang's training data expertise is Meta's stated competitive advantage for the new model family.
Will Meta's Avocado and Mango models be open source?
Partially. Meta plans to open-source versions of both models after safety review, but will keep proprietary versions of the strongest capabilities closed — a departure from the fully open LLaMA approach.
How do Meta's new models compare to Claude and ChatGPT?
No benchmarks have been published yet. Avocado and Mango have not launched as of April 8, 2026. Claude (Anthropic) and GPT-5.4 (OpenAI) remain the leading production models until launch data is available.
When will Avocado and Mango be released?
No firm release date has been confirmed. Axios reported in April 2026 that Meta is 'preparing to release' the models, suggesting a near-term launch. A phased rollout — proprietary API access first, open-source versions later — is the reported plan.
