Many users complain that Fable falls back to Opus 4.8 too quickly because of strict guardrails. We need guardrails. But what happens when safety makes a model feel worse, especially if other models answer more freely? That is the dilemma in this week’s Quantized AI News soverius.ai/blog/quantiz...

Quantized AI News 26/05: The Price of Control in Frontier AI

And here’s our article for the week! 🚀 This time, we’re diving into A2UI - in my opinion, one of the most critical topics at the intersection of AI and Frontend development right now.

AI offers massive potential for UIs. The interface can be dynamically generated for each user. A key technology is #A2UI, which is framework-agnostic. Our new post covers: ✅ What is A2UI? ✅ How does it work? ✅ How to run it fully autonomously. soverius.ai/blog/behind-...

GPT 5.5 has doubled its prices compared to GPT 5.4. GitHub Copilot just switched to token-consumption models, and Opus 4.7... well 🤷. The era of "subsidized AI" is ending. Vendors need to earn money, and I expect prices will increase even further in the short term. soverius.ai 🧵 1/6

Clarifying my chat with @brandonroberts: Analog is a NECESSITY for serious Angular testing. Why? ✅ Full Vitest ecosystem (plugins/IDE support). ✅ No lock-in: Keep CLI for builds, use Analog for tests. ✅ It's the standard: Angular's Vitest move validates this path. #Angular #Vitest

🧪 Enjoyed the conversation between @manfredsteyer.bsky.social and @rainerhahnekamp.bsky.social about the future of testing with @angular.dev and @vitest.dev. I appreciate the recommendation of @analogjs.org for previous versions of Angular & compatibility with IDEs www.youtube.com/watch?v=1ac9...
