A Senior ML Engineer’s perspective on production constraints, rules vs ML and the workflow behind large-scale recommender systems…We talked about his rise from software engineering to machine learning at Instacart, how does he decide between rules based vs ML approaches and how he approaches the work now as a more senior stakeholder.
Better prompts. Better AI output.
AI gets smarter when your input is complete. Wispr Flow helps you think out loud and capture full context by voice, then turns that speech into a clean, structured prompt you can paste into ChatGPT, Claude, or any assistant. No more chopping up thoughts into typed paragraphs. Preserve constraints, examples, edge cases, and tone by speaking them once. The result is faster iteration, more precise outputs, and less time re-prompting. Try Wispr Flow for AI or see a 30-second demo.

Let’s delve into five paramount generative AI applications within the FinTech realm, showcasing their potential to elevate operational efficiency and customer service. Let’s see!

Anthropic’s latest release is getting a new release Cowork, Anthropic’s agentic tool launched earlier this month, has a new plug-ins feature to make the non-coder translator even more powerful for enterprise users. The plug-ins are designed to automate “specialized” tasks within a company’s various departments.

Researchers already automate experiments, but they still read hundreds of papers to extract laws. Theorizer flips that workflow by reading the literature first and writing theories directly. The striking part: it synthesizes explicit scientific laws from up to 100 papers per query.

I work as a data scientist and I usually build models in a notebook and then create them into a python script for deployment. Lately, I’ve been wondering if this is the most efficient approach and I’m curious to learn about any hacks, workflows or processes you use to speed things up or stay organized…Especially now that AI tools are everywhere and GenAI still not great at working with notebooks…

More big news this week for Nvidia. China has given its top AI startup DeepSeek approval to buy the chip leader’s H200 artificial intelligence chips with regulatory conditions that are still being finalized. The deal would add onto the recent Chinese purchase of more than 400,000 H200 chips to ByteDance, Alibaba, and Tencent.

Remember Bluesky? It’s still kicking, and it’s released its first transparency report. The report documented actions taken by its Trust & Safety team and the results of other initiatives, but also notes that, during the past year, users made 1.41 billion posts on the platform which represented 61% of all posts ever made on Bluesky.

Invideo launched AI Motion Graphics with Anthropic. Think vibecoding for motion design. The cost of professional motion work just dropped to zero. All generated from a single prompt. Small teams can now produce the same quality as large agencies.

In YouTube's official 2026 roadmap, Neal Mohan directly acknowledged concerns about low-quality AI content flooding the platform. The company is building on its spam and clickbait systems to reduce the spread of “repetitive” AI videos.
