Meta Muse Spark: Everything You Need to Know About Meta’s New AI Model

Meta Muse Spark just scored 52 on the Artificial Analysis Intelligence Index v4.0, placing it in the top 5 overall behind GPT-5.4 (57), Gemini 3.1 Pro (57), and Claude Opus 4.6 (53). That makes it the most capable AI model Meta has ever built, and it is completely free to use. Built by Meta Superintelligence Labs (MSL), the team led by Alexandr Wang, Muse Spark is the result of a nine-month ground-up rebuild of Meta’s entire AI infrastructure. But raw rankings only tell part of the story. Muse Spark beats every competitor on medical and health benchmarks, ranks second in multimodal vision understanding, and introduces a unique Contemplating mode that […]

Gemini 3.1 Pro Is Here: Benchmarks, Pricing, and How It Stacks Up Against Claude and GPT

Google released Gemini 3.1 Pro on February 19, 2026, and its benchmark numbers are hard to ignore. The model scored 77.1% on ARC-AGI-2, a test specifically designed to prevent AI from relying on memorised answers — it forces genuine reasoning on problems the model has never encountered before. That is more than double the 31.1% scored by Gemini 3 Pro when it launched just three months ago. This article covers everything you need to know about Gemini 3.1 Pro, including what changed from the previous version, how it performs against Claude Opus 4.6 and GPT-5.2, what it costs, and where you can access it right now. If you’re deciding whether […]

Elon Musk’s xAI Launches Grok 4.1: Now the Highest-Rated LLM on LMArena

Today, November 17, 2025, xAI has officially rolled out Grok 4.1, the latest iteration of its flagship large language model, across grok.com, the 𝕏 interface, and the iOS and Android apps. The update arrives after a two-week silent production test and aims to deliver more natural conversation, stronger emotional intelligence, tighter safety controls, and dramatically improved real-world reliability. Unlike typical incremental updates, Grok 4.1 represents a noticeable shift in how xAI tunes and deploys its models: it introduces deeper reinforcement learning on style, personality, and alignment, while preserving the factual accuracy and reasoning depth Grok 4 was known for. Below is everything you need to know — benchmarks, new capabilities, safety upgrades, and how […]
