Meta this week announced its latest large language model, Muse Spark. The LLM, which select users can access through a private API preview, fills the shoes left vacant by Llama 4. Meta moved on from Llama 4 after disappointing uptake.
The biggest difference?
Whereas Llama 4 was open-source, Muse Spark is closed, putting it on a collision course with Google Gemini, Anthropicβs Claude Opus, OpenAIβs ChatGPT, and xAIβs Grok. According to benchmark test results released by Meta, Muse Spark is βcompetitiveβ with all four but lands in the middle overall.
Meta has gone to great lengths to win the AI race, bringing Alexandr Wang over from Scale AI, aggressively headhunting engineers, and, recently, shifting its focus away from the metaverse.
Now, itβll need to do a bit more to pull people away from their preferred models. While itβs prepping its launch, competitors arenβt standing pat.
This week alone, OpenAI launched ChatGPT on CarPlay, and Anthropic came out with Claude Managed Agents and its Claude Advisor tool.
