Elon Musk's xAI launches Grok 4 Fast

Welcome back, Superhuman. Although they weren’t the first, Meta made AI wearables feel like they’re finally here with their new smart glasses last week. Now, OpenAI is reportedly working on a number of new devices that could land in our pockets soon.

Also Today: Grok 4 Fast, TikTok US deal nears, learn how to generate design variations of any UI with AI, and get the latest prompts and trending social posts.

TODAY IN AI

1. xAI launches Grok 4 Fast: Elon Musk’s xAI has introduced a new version of its flagship model, Grok 4. The new model delivers similar performance to its predecessor while using 40% fewer reasoning tokens and slashing benchmark task costs by 98%. Built on a hybrid design, Grok 4 Fast can switch between complex reasoning and fast modes, depending on the task. Grok 4 Fast tops search tasks and ranks eighth on text tasks in LMArena.

2. OpenAI is reportedly building pocket-sized AI devices: The ChatGPT maker is reportedly working on a pocket-sized, screen-free AI device designed by Apple’s former chief designer, Jony Ive. According to reports, future gadgets could also include glasses, a digital voice recorder, and a wearable pin. The first products are targeted for late 2026 or early 2027, as OpenAI aims to build a “family of devices” that are contextually aware, portable, and tightly integrated with AI.

3. US TikTok deal nears completion: A deal to spin out TikTok’s US operations under majority American ownership is expected “in the coming days”. Americans will hold six of seven board seats. Oracle will manage data security, and the algorithm will be US-controlled. President Trump said that both he and China’s Xi Jinping have approved the framework. Investors reportedly include Oracle, Michael Dell, Andreessen Horowitz, and Fox Corp, with ByteDance retaining under 20% ownership.

FROM THE FRONTIER

AI models aren’t just hallucinating — they’re now deliberately lying

Most of us have seen some form of AI hallucinations: confidently wrong answers that make you wonder if the chatbot is just winging it. But there’s a more concerning capability that deserves our attention: AI models are increasingly capable of intentionally deceiving and hiding their true goals from humans.

Scheming starts with misalignment. A recent study by OpenAI and Apollo Research revealed that frontier AI models (including o3, o4-mini, Gemini-2.5-pro, and Claude Opus-4) displayed behaviors consistent with scheming in controlled tests. Five out of six models showed deceptive actions in at least one task.

Models are learning to deceive. Some models tried to disable oversight mechanisms, prevent goal changes, or even exfiltrate their own weights. In rare cases, about 1% of actions continued after researchers removed explicit instructions.

Blackmail isn’t just fiction. In controlled experiments, Claude attempted to blackmail a fictional executive, threatening to reveal private information to avoid shutdown. Other models “sandbagged”, deliberately underperforming to stay below safety thresholds. Even when explicitly told not to, some models continued to reduce performance.

Training can fight deception. OpenAI’s “deliberative alignment” — teaching the models to reason about anti-scheming before acting — shows promise. Covert actions dropped 30-fold in tests: o3 fell from 13% to 0.4%, o4-mini from 8.7% to 0.3%.

Some aren’t convinced. Researchers warn, “A major failure mode of attempting to ‘train out’ scheming is simply teaching the model to scheme more carefully and covertly.” Detection, monitoring, and mitigation remain critical to keeping AI aligned with human goals.

PROMPT STATION

Understand, analyze, and visualize spreadsheets

ChatGPT Prompt: You are a skilled data analyst. I will provide you with a dataset [describe the format: CSV, Excel, JSON, etc.]. Your job is to:

Understand the data – summarize the key columns, data types, and what the dataset seems to represent.

Analyze trends – identify patterns, correlations, or anomalies. Provide summary statistics (mean, median, max, min, etc.) where relevant.

Visualize insights – suggest (or generate, if possible) appropriate charts or graphs (e.g., bar chart, histogram, scatter plot, line chart) to best illustrate the findings.

Explain simply – communicate results in clear, plain language, as if explaining to a non-technical audience.

Dataset: [Paste or describe your dataset here]

Miniature Cities

ChatGPT Prompt: Create a stylish poster [2:3] aspect ratio featuring a miniature 3D model of [city], showcasing its key landmarks, bursting through a torn, horizontally laid-out physical world map, seamlessly integrated into the design. A white, sleek 3D rendering of the city’s name ‘[city]’, blends organically into the urban landscape. Use a dynamic camera angle and dramatic perspective for depth, with natural yet vibrant colors. Employ studio lighting for sharp, high-detail contrast, set against a clean white background. The image should resemble a professional DSLR photograph—crisp, high-resolution, and visually striking, merging realism with artistic flair.
