Llama 4’s Rocky Debut

Meta Platforms on Saturday released two versions of Llama 4, the newest generation of its flagship open-source large language model, called Llama 4 Scout and Llama 4 Maverick. The release came a day after we reported that Meta had hit some snags with the new model, which had delayed its release a bit. 

At first glance, the new AI seemed to work well. LMArena, an organization that benchmarks LLMs, ranked a version of Llama 4 Maverick as the best-performing open-source LLM out there. 

But as developers dug into the new models, they quickly realized that there was more to the story. It’s beginning to look like Meta may have rushed the release.
