Everything else that happened in AI last week
Claude Skills: An AI Tool Ecosystem
Anthropic launched Claude Skills, a new system that allows companies to build their own AI toolkits. It organizes workflows, internal processes, and scripts into convenient packages that an AI assistant can automatically access when a task arises.
Why it matters for business:
Efficiency: AI automatically chooses the right process, reducing human error.
Integration: Multiple departments (e.g., marketing and finance) can be connected in a single workflow.
Scalability: Companies can roll out new processes or policy updates quickly through AI.
OpenAI Hires a Theoretical Physics Expert
OpenAI brought on physicist Alex Lupsasca as the first researcher for its new OpenAI for Science division, aiming to accelerate AI applications in research - from mathematics to physics.
Lupsasca reports that GPT-5 Pro solved in 30 minutes a problem that had taken him days. OpenAI says the new model shows real potential for scientific discovery, from quantum theory to biology.
Why it matters for business:
Innovation speed: AI accelerates research and experiments, allowing new products and solutions to reach the market faster.
Data analysis: AI can process complex scientific or technical data, helping companies make more informed decisions.
Efficiency: Less time and resources are spent testing experiments or hypotheses.
Google Unveils Veo 3.1
Google introduced Veo 3.1, a new video generation model promising higher quality, more realistic scenes, and new creative editing features for filmmakers.
Supports up to three reference images to keep characters consistent across scenes.
Allows specifying start and end frames, with smooth transitions and synced audio.
Scene extension lets users create videos up to 1 minute by stitching segments seamlessly.
Available in standard and fast versions across Google’s ecosystem, including Flow, Vertex AI, and Gemini.
Why it matters for business:
Quality: Consistent characters and smooth transitions enhance visual content for branding.
Creative flexibility: Users can control reference images, key frames, and extend scenes.
Competitive advantage: High-quality visuals help businesses stand out and engage audiences more effectively.
Faster production: AI enables professional video creation in a fraction of the time.
Claude Haiku 4.5 – Powerful AI, Faster and Cheaper
Anthropic released Claude Haiku 4.5, a powerful AI model performing like their flagship model but faster and more cost-efficient. It supports multiple agents simultaneously and outperforms previous models in math, computing, and agentic tasks.
Why it matters for business:
Lower costs: $1 per million input tokens makes AI usage more frequent and economical.
Speed and efficiency: Faster performance and support for multiple agents; Sonnet 4.5 coordinates complex tasks.
Easy integration: Accessible through Claude Code or API, making adoption into existing workflows seamless.
Google and Yale Discover a New Cancer Treatment
Researchers at Google and Yale unveiled C2S-Scale 27B, a foundational model that discovered a new cancer treatment working in living cells.
The AI “reads” cells like a language, predicting their behavior and treatment response.
It identified compounds that help the immune system spot tumors, only under specific signals.
Discovered silmitasertib, a drug previously not linked to immune response against cancer cells.
Why it matters for business:
Innovation opportunities: AI-driven discovery demonstrates how businesses can leverage AI for innovation.
Speed and efficiency: Quickly analyzes large datasets, saving time and resources compared to traditional research.
Tech integration: Pharma, biotech, and healthcare can use such systems for product development and research optimization.
AI Content Online Briefly Surpassed Human-Written Articles
A Graphite study found that AI-generated content briefly overtook human-written articles online in late 2024. Now, the web is roughly evenly split.
Analyzed 65,000 articles from Common Crawl (2020–2025) using Surfer AI detector.
After ChatGPT launched, AI content spiked in November 2024.
Growth has plateaued; AI content now matches human-written levels.
Stagnation is linked to AI content not always performing as well in search engines as human content.
Why it matters for business:
Content strategy: Businesses must know AI content spreads fast but may not rank as well as human-written content.
Efficiency: AI accelerates content creation but needs quality oversight.
Competitive advantage: Understanding AI’s strengths and limits allows businesses to adapt faster.
Elon Musk Preparing an AI-Generated 3D Game by 2026
xAI hired Nvidia specialists to develop models that generate interactive 3D gaming environments. The goal is to release a playable game by 2026.
This summer, Zeeshan Patel and Ethan He joined to develop AI capable of understanding physics and object interactions. xAI is recruiting for its “omni team” and recently advertised a “video game mentor” role to train Grok AI in game design.
Why it matters for business:
New AI possibilities: Interactive gaming worlds open new market segments and user experiences.
Faster production: AI can generate complex environments faster than traditional methods.
Innovation advantage: Early adopters of AI-created games can gain a competitive edge.
GPT-5 Models Show 30% Less Political Bias
OpenAI published research showing GPT-5 models exhibit 30% less political bias than previous versions, based on 500 prompts across political topics.
Performed best on emotionally charged prompts, though highly liberal prompts still triggered slightly more bias.
Less than 0.01% of ChatGPT conversations show political bias according to real usage data.
Why it matters for business:
Content objectivity: Reduced bias ensures more reliable information for clients and employees.
Decision quality: Lower bias enables more objective business decisions based on AI insights.
