Flows Agent lets you iterate through conversation. Tell it to try a warmer voice, swap the background, or generate a version in Spanish. The agent modifies the pipeline and re-runs without rebuilding from scratch.

Easy AI demos, hard production: weaknesses exposed
By

Here is the uncomfortable reality I observe in companies: AI demos are easy. AI in production is not. Once AI moves past the pilot stage, it begins to expose every weakness in the foundation: β Fragmented systems

AI pilots fail mainly because of the company, not the model

Most AI pilots do not fail because the model is weak.
— Ronald van Loon (@Ronald_vanLoon) 4 juin 2026
They fail because the enterprise underneath it was never built for production AI.

Thanks Peter! Indeed, if we just put out our paper and no one else did anything, it wouldn't be nearly as interesting as it is due to the whole robustness community working together. As I recall, you famously also worked on this area (Byzantine robustness)

Pipeline order is a hyperparameter for optimizing LLM execution strategies
By
–
5/5 Takeaway: pipeline order is a hyperparameter. If you're already paying for parallel rollouts, reuse them – they're relevant context, not just candidate answers. Full write-up: [

AI21 Labs: Reversing agent pipeline order achieves SOTA results
By
