About Grok
Grok is a multimodal AI assistant developed by xAI that provides real‑time access to information from X and is integrated with Tesla vehicles and the broader X platform. It positions itself as an on‑device conversational interface linking social media content, automotive data, and other services within the ecosystem created by Elon Musk’s companies.
Elon Musk Challenges FTC Data Audits for X Again
Elon Musk is once again attempting to avoid compliance with a Federal Trade Commission (FTC) order that requires regular audits of X's data-handling practices. The order, imposed in 2022, was a result of a settlement following a data mishandling incident involving user contact information. Musk argues that the order should be terminated because the company structure has changed, with X being merged into xAI and then SpaceX. The FTC, however, maintains concerns about X's ability to uphold privacy standards, citing past issues with staff reductions and Musk's interference in internal systems. In 2023, Musk previously tried to have the order revoked, but the court denied his request. The FTC remains focused on ensuring that user data is protected, particularly as Musk's leadership has led to significant changes in company operations.

xAI's Colossus 2: World's First Gigawatt Datacenter
xAI is building Colossus 2, a datacenter that will be the first in the world to reach a capacity of one gigawatt. This follows the success of Colossus 1, which was completed in just 122 days and remains the largest fully operational single-coherent cluster. Colossus 1 has roughly 200,000 H100/H200s and ~30,000 GB200 NVL72, but its capacity is limited to around 300 MW.

Elon Musk's Grok AI Lacks Adoption
A Reuters report has found that Elon Musk's 'truth-seeking' AI chatbot, Grok, is not widely used. The platform barely appears in federal records of US government AI usage last year. This lack of adoption raises questions about the effectiveness of Grok. Despite its ambitious goals, the chatbot seems to be struggling to gain traction.

Claude Code sessions are no longer trapped in one terminal. Because a session is tied to your Claude account, it follows you across your devices — start a task at your desk, check on it from your phone, steer it from the couch. What it is, where it runs (CLI, desktop, web, IDE), and how to use the everywhere part — including why coding you can supervise from anywhere is a real accessibility win.

Grok 4.3 is the current flagship model in the grok family, released on 30 April 2026 and listed as active. It offers a one‑million‑token context window and is positioned as cost‑efficient, with pricing of $1.25 to $2.50 per million tokens. The version emphasizes strong agentic tool‑calling capabilities and native real‑time web access.
Grok 4.20 is an active, reasoning‑tier model in the Grok family released on 1 February 2026. It features a very large context window of one million tokens and introduces an extended‑reasoning “Think Mode” aimed at reducing hallucinations, which are reported as the lowest within the Grok series.
Grok 4 Fast is a budget‑oriented, high‑volume variant of the grok family released in September 2025 with a two‑million‑token context window and fast‑tier performance characteristics; it was marketed under both “Grok 4 Fast” and “Grok 4.1 Fast.” The model was retired on 15 May 2026, after which requests were redirected to the pricing scheme of Grok 4.3.

Grok 2.5 is an open‑weight iteration of the Grok family released on 1 August 2025 and now listed as superseded.
