Elon Musk just confirmed that xAI is actively training Grok 5, targeting an early 2026 release. Packing an eye-popping 6 trillion parameters—double the size of Grok 3 and Grok 4—the model will integrate real-time multimodal processing across text, vision, and audio, with Musk betting it will be the world's smartest AI by a wide margin.
xAI just open-sourced Grok 2.5, releasing the weights for its top 2024 model on Hugging Face under a custom community license. It is free for research and non-commercial projects but bans training rival models. Musk also promised Grok 3 will go open source in about six months.
Microsoft just officially brought xAI’s Grok 3 and Grok 3 mini to its Azure AI Foundry platform. Hosted and billed directly by Microsoft with full enterprise SLAs, the surprise addition deepens Azure's model lineup—and adds another awkward wrinkle to Microsoft’s increasingly tense alliance with OpenAI.
Elon Musk just announced that an early beta of Grok 3.5 is dropping next week exclusively for SuperGrok subscribers. Musk claims the model can accurately answer complex questions about rocket engines and electrochemistry by reasoning from first principles to generate answers not found on the web.
xAI just rolled out Grok 3 Mini, bringing built-in reasoning to developers at a fraction of the cost of legacy models. Available now via API alongside the standard Grok 3, the Mini version serves full reasoning traces starting at $0.30 per million input tokens. It puts serious price pressure on rivals while rivaling top-tier reasoning benchmarks.
xAI just released the API for its flagship Grok 3 and Grok 3 Mini reasoning models. Standard Grok 3 matches Claude 3.7 Sonnet pricing at $3 per million input tokens and $15 per million output tokens, with faster tiers available. Notably, the API maxes out at a 131,072 tokens context window, falling short of the 1 million tokens xAI promised in February.
xAI just rolled out an uncensored voice mode for Grok 3 subscribers that goes where ChatGPT won't. Users can toggle personalities like an "unhinged" mode that curses and screams before hanging up, or an 18+ "Sexy" mode built for phone sex. Why it matters: While OpenAI keeps tight guardrails on voice AI, xAI is doing the exact opposite by letting its model run completely wild.
Elon Musk just made xAI's flagship Grok 3 model temporarily free for everyone, no subscription required. Users can test drive the new "Think" reasoning and "DeepSearch" modes across the web and app, though paying tiers still keep server priority, voice mode, and the extra-heavy Big Brain features.
Elon Musk's new Grok 3 model might top benchmark leaderboards, but security firm Adversa AI just found it failed three out of four basic jailbreak tests and leaked its entire system prompt. Why it matters: as vulnerable models power autonomous AI agents, simple prompt injections could turn into real-world corporate security breaches.
Elon Musk’s xAI just released its latest flagship Grok 3 family, introducing specialized reasoning models to compete with o3-mini alongside a new DeepSearch tool. Trained on roughly 200,000 GPUs, it claims top benchmark scores and offers a high-compute Big Brain mode. Access is currently rolling out to X Premium+ subscribers.
Elon Musk's xAI just rolled out Grok 3, trained on roughly 200,000 GPUs with 10x more compute than its predecessor. The lineup includes new reasoning models designed to rival OpenAI's o3-mini on tough math problems, alongside a web research tool called DeepSearch. It is rolling out first to X's Premium+ subscribers.
Elon Musk just revealed that xAI's upcoming Grok 3 has finished pretraining, using 10 times more compute than Grok 2. He added that the new flagship model is coming soon. Why it matters: xAI is rapidly scaling its infrastructure to challenge OpenAI and Google at the very top of frontier AI.
Elon Musk just revealed that xAI plans to launch Grok 2 this August, promising a major leap in real-time knowledge and reasoning. Musk noted the team did heavy lifting to purge junk from Internet training datasets, while teasing that Grok 3—powered by 100,000 Nvidia H100 GPUs—is slated for the end of the year.
