⚡️ Muse Spark: Meta's Answer to GPT-5.4 and Opus 4.6

Meta Superintelligence Lab, founded by Zuckerberg last year following the disappointing performance of the Llama 4 models, has released its first neural network: Muse Spark.

According to benchmarks, Muse Spark comfortably outperforms Grok 4.20, and in most tests covering coding, agentic tasks, general knowledge, and abstract reasoning, it holds its own against Claude Opus 4.6 and GPT-5.4.

✖️ The End of Open Source

Muse Spark is already running across Meta's services, with API access set to roll out soon—but releasing the model weights to the public doesn't appear to be on the table anymore.

Llama models are still widely used by the community and researchers: the smaller versions are easy to fine-tune for specific tasks, free to use, and come without licensing headaches (though Chinese open-source models are steadily eating into Llama's dominance).

That said, the billions poured into the Superintelligence Lab have to pay off somehow, so AI at Meta, at least on the chatbot side, is now first and foremost a commercial play.

✅ On the flip side, greater responsibility to paying users also means greater accountability, so you can be pretty confident Meta has no intention of staying in the AI second division.

Do you think Meta can become an AI leader?

❤️ — maybe, they've got a shot
🔥 — no way, they're too far behind
