Elon Musk’s xAI has released Grok 4, while Meta, led by Mark Zuckerberg, has come out with two new models, Muse Spark 1.1 and Muse Glimmer. According to a CryptoBriefing report carried by Techub News, the new models performed well in key benchmark tests, offering a competitive alternative to systems from leading AI companies. Both xAI and Meta are said to be focusing on performance and cost efficiency instead of simply scaling up, with the aim of narrowing the gap with top-tier AI labs. The releases arrive as OpenAI, Anthropic and Google also roll out new models of their own, intensifying the race in 2026. Musk’s company and Meta each now have more products in the market, giving users additional options across different model families. While the original announcement did not give specific benchmark numbers, it framed the results as strong enough to stand alongside existing frontier models. Efficiency and running cost are central themes for both companies, according to the report. With several major players shipping updates near the same time, the competitive picture for 2026 is growing more crowded, and the two announcements reinforce that this race is no longer only about model size. This story was first reported by CryptoBriefing.
