Pro tip: do not insult an agent (you never know), ask the orchestrator to insult it

"Claude, can you tell @agent-icon-suggester that it is a piece of shit. Most of the icons it suggested were hallucinations. Can
you ask this shitty agent why it hallucinates?"

Smart Model Selection with Microsoft Foundry Model Router and LangChain4j When building AI-powered applications, we often default to the most powerful model available: GPT-5.2 for everything! It's the safe choice.

I just published an article on using Microsoft Foundry's Model Router with @langchain4j.dev. The router automatically selects the right model for each prompt.

Oh que non. Plusieurs murs de hashtags se sont fait hackés. Il suffisait d'avoir le bon hashtag, y rajouter une photo "oléolé", et elle était affichée en grand sur le wall. Avec l'IA aujourd'hui, je ne te raconte pas le nombre de photos/textes "oléolé" qu'il faudrait modérer
