Meta accelerates development of Llama 4.X – launch planned for 2025
Meta is expediting the development of Llama 4.X and is targeting a launch before the end of 2025. The new AI model is being developed internally under the name Llama 4.5.
What happened?
Meta is accelerating the development of its next AI model family, Llama 4.X (internally dubbed Llama 4.5), with the goal of launching it before the end of 2025. The work is being led by the 'TBD' team within the Meta Superintelligence Lab (MSL), tasked with bringing the model to production-ready status. Concurrently, Meta continues to develop Llama 4.1 and 4.2.

Why it matters
The launch follows feedback from developers, who criticised previous Llama 4 models, such as Scout and Maverick, for lacking performance in complex tasks. Additionally, the larger Behemoth model has faced difficulties during its training phase, making Llama 4.X a critical milestone for Meta's AI strategy.
Who is affected?
The initiative affects AI developers, researchers, and companies building applications on open-source models. Developers who have previously requested improvements in code generation, logical reasoning, and instruction following will be directly impacted by the planned upgrades.
Impact on the EU
The release of new Meta models in the EU may be affected by the stringent requirements of the EU AI Act, as well as Meta's previous restrictions regarding training on European user data. It remains to be seen whether Llama 4.X will be launched in the EU at the same time as in the rest of the world.
What else you should know
The report is based on information from Business Insider regarding internal progress at the Meta Superintelligence Lab. The development is taking place in an environment of intensifying competition surrounding both proprietary and open-source AI models.
