Meta is reportedly working on a new AI model called 'Avocado' and it might not be open source

Meta is developing a new AI model codenamed "Avocado" that could mark a dramatic shift from the company's open-source approach, with the model expected in 2026 and likely to be proprietary. This pivot comes as CEO Mark Zuckerberg faces mounting pressure to compete with OpenAI and Google, while Meta's current Llama 4 model has been delayed and reportedly disappointing. The change represents a complete reversal for Zuckerberg, who previously championed open-source AI development but now appears willing to abandon that philosophy to avoid falling behind rivals.
