Good morning, AI enthusiasts. xAI is officially rolling out Grok Imagine, its new tool for ultra-fast AI video generation with native sound.

By claiming to produce videos in just half to a quarter of the time it takes to generate AI images, the company is pushing the speed limits of creative AI. But the big question remains: can it match the cinematic quality of Google's leading Veo 3 model?


In today’s AI rundown:

  • xAI rolls out Grok Imagine AI video generator

  • Google releases Gemini 2.5 Deep Think

  • How to extend AI videos beyond 8 seconds

  • Study: Anthropic looks into AI’s personality shift

  • 4 new AI tools & 4 job opportunities

The Rundown: xAI is officially rolling out Grok Imagine — its new AI image and video generator — to all SuperGrok and Premium+ X subscribers on its iOS app, entering a space dominated by Google, OpenAI, Runway, and China’s viral generators.

The details:

  • With Grok Imagine, users can turn any simple text prompt or image into a 15-second video, complete with native audio, in seconds.

  • The model even creates images from text, which can eventually be animated into stylized videos, and continues to auto-generate as users scroll down.

  • In terms of quality, the videos generated by Imagine look more “AI-generated” as compared to other video models, delivering cinematic outputs.

  • Elon Musk said the model “should get better every day” while emphasizing that it makes videos in 1/2 to 1/4 the time rivals take to make a single image.

Why it matters: While Grok Imagine doesn’t appear to outperform other top video generators on the market, xAI is aiming to offer a fresh take on video generation with it’s playful and unfiltered style. But as we’ve seen with the chatbot, that approach can sometimes lead to unexpected (and even controversial) results.

🧠 Google's ‘multi-agent’ Gemini 2.5 Deep Think

The Rundown: Google released Gemini 2.5 Deep Think, its first publicly available multi-agent model that does “parallel thinking” to help researchers, scientists, and academics tackle complex problems.

The details:

  • First announced at I/O 2025, Gemini 2.5 Deep Think is a variant of the model that won the gold-medal standard at this year’s International Math Olympiad.

  • When handling hard questions, the model spawns multiple agents to explore possible solutions in parallel and then decides the best answer from them.

  • It scored 34.8% on Humanity’s Last Exam, surpassing Grok 4 and OpenAI’s o3, while delivering SOTA performance on coding and web development tasks.

  • Gemini 2.5 Deep Think is rolling out to Gemini app users on Google’s $250/month Ultra plan, with the IMO variant accessible to select researchers.

Why it matters: While Meta is vying for “personal” superintelligence, Google is taking a different route — empowering researchers, scientists, and academics with a parallel-thinking AI that, instead of offering direct answers, spawns a team of expert minds to tackle problems from multiple angles before converging on a solution.

AI TRAINING

🎬 How to extend AI videos beyond 8 seconds

The Rundown: In this tutorial, you’ll learn how to bypass Google Veo 3’s 8-second clip limit using Google Flow’s frame-to-video feature that lets you create longer videos with character consistency.

Step-by-step:

  1. Create your initial 8-second video using “Text to Video” in Flow (choose Veo 3 for audio)

  2. Open the scene editor and save the final frame using “Save frame as asset”

  3. Start a new “Frames to Video” generation using your saved frame, and describe the next sequence

  4. Combine both clips in the timeline editor and trim for smooth transitions

Pro tip: Repeat this process multiple times to create even longer videos while maintaining perfect character consistency throughout.

AI RESEARCH

😈 Study: Anthropic looks into AI’s personality shift

Image source: Anthropic

The Rundown: Researchers at Anthropic just identified “Persona Vectors,” neural network activations that help understand and control unexpected (sometimes even unsettling) behavioral changes demonstrated by AI models.

The details:

  • While trained to be helpful and honest, AI models can sometimes drift away, exhibiting unexpected personality traits like sycophancy or racism.

  • When these behavioral changes happen, certain patterns of activity or persona vectors are seen within an AI’s neural network, like the human brain.

  • Researchers extracted these vectors by comparing activation patterns between opposing behaviors (evil vs non-evil).

  • They focused on three traits—evil, sycophancy, and hallucination—using persona vectors to reduce their emergence and narrow down causative data.

Why it matters: With popular AI tools like ChatGPT and Grok previously showing behaviors such as sycophancy and antisemitism, it’s clear that no model is immune to behavioral drift. Anthropic’s research offers a promising path to understanding these shifts at the neural network level—and using that understanding to build safeguards.
