xAI just rolled Grok 4.3 out to the full API on April 30, 2026, two weeks after a $300/month beta locked behind SuperGrok Heavy. The bigger story is the price reset. Grok 4.3 now runs at $1.25 per million input tokens and $2.50 per million output tokens, an input cut of roughly 40% and an output cut closer to 60% versus Grok 4.20. It scores 53 on the Artificial Analysis Intelligence Index, slotting just above Claude Sonnet 4.6 and well below GPT-5.5, Claude Opus 4.7, and Gemini 3.1 Pro Preview. This Grok 4.3 review covers what actually changed since the April beta, where Grok now stands against the other frontier […]

Update — May 2, 2026: Read our new Grok 4.3 review. ChatGPT now runs on GPT-5.5, launched on April 23, 2026, while Grok is powered by Grok 4.3 (released April 30, 2026) and the older Grok 4.20 from xAI.

So which one should you actually use? We compared Grok vs ChatGPT across benchmarks, pricing, coding, writing, […]

You probably have one of the most powerful productivity tools ever created sitting right in your pocket – artificial intelligence. Whether it’s ChatGPT, Google’s Gemini, or any other AI assistant, these tools can handle tasks that would normally take you hours. Yet most people try them once or twice, get disappointing results, and give up thinking AI isn’t worth the hype. If you’ve asked ChatGPT to “help with work stuff” or “how to make my life easier” and received generic, unhelpful responses, you’re not alone. The reason is that these tools need specific, well-structured instructions to give you genuinely useful results. Ask vaguely, and you’ll get vague answers. Ask specifically, […]

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 […]

Today, October 27, Elon Musk’s xAI has officially launched Grokipedia, a new AI-powered encyclopedia that aims to challenge Wikipedia’s dominance by rethinking how online knowledge is written, fact-checked, and maintained. Grokipedia, with roughly 885,000 articles available at launch, wants to rebuild the internet’s reference layer from scratch with artificial intelligence at the center. Announced at the end of September 2025, the open-source encyclopedia is pitched as a “massive improvement over Wikipedia” and, in Musk’s words, a “necessary step toward xAI’s goal of understanding the universe.” At its core, Grokipedia aims to be an alternative to Wikipedia by explicitly tackling what Musk and supporters describe as “bias,” “propaganda,” and institutional or ideological slants in mainstream reference […]

Amazon is preparing fresh corporate cuts, with its People eXperience & Technology (PXT) HR group expected to be hit hardest—reports say up to 15% of PXT could go, and other orgs may see targeted reductions. Amazon hasn’t given official numbers or timing. The move lands as the company pours money into AI infrastructure and embeds automation deeper into back-office workflows. Treat Amazon as a signal rather than an outlier. Across tech in 2025, companies are trimming roles most exposed to automation while shifting spend to AI models, data centers, and tools. By late September, trackers show tens of thousands of tech job cuts this year—even as hiring stays hot for […]
