One of my fondest memories of being in #Belgium 🇧🇪 is the introduction to #Kwak & how to properly drink from the “beaker” … it got me the 1st time. Thanks to a mate who both got me this set like a year ago & now today the signage! Pays to have good mates!

As my Saturday gift 🎁 to everyone exploring the new local @OpenAI models + #Observability: Built today in hours → local on my #MacBookPro #gpt-oss:120b w/ completions, evals, & multi-platform traces (#OpenAI, Aspire, Azure Monitor). Repo: github.com/fabianwillia... #AI #LLM

I really like using the new local #OpenAI #GPTOSS 120Billion parameter model on my #MacBook 💻 the performance is amazing and synthesis is precise, you can even tune the reasoning & #MOE mixture of experts to suit quick answers or deep thought! Amazing OFF the Internet approach!

Just ran @OpenAI #GPT0SS120B locally on my #MacBookPro M3 Max (128GB, 40‑core GPU) 🚀 Asked a tricky logic puzzle… it answered before I finished explaining. Watch the drive‑by demo 👉 go.macona.org/openaigptoss... #AI #M3Max #LocalAI #OpenAI #SmallLanguageModels #SLM #LocalAgents

Built this over the weekend: a working #Agent-First e-commerce flow where #AI agents take on the roles of greeter, sales rep, and checkout assistant. No cart. No confusion. Just smart, structured convo → #Stripe checkout. fabswill.com/blog/agentfi... #MCP #NextJS #SemanticKernel #ConversationalUX

The future web isn't static. It's agent-aware. At www.andmyagent.com, I built: • Vector Search (#Qdrant) • Narrative AI (#GPT-4o) • Agents that talk to each other (#MCP Server) • Full observability (#OpenTelemetry + Aspire) Try it now before my VM sleeps 😴 at midnight ET it will wake up back tho.

I was sitting staring at da trees outside my window on this final day of #FHL at work & had this #thoughtexperiment ~ what if we #humans or rather all living things were #agents as we think of #AI agents? that'd mean we're working towards a shared/common goal innit? what is it? & who's directing it?

🔍 Mastering #Observability in GenAI agents? We’re in the Agent-to-Agent era: #Salesforce → #SAP → #M365 Copilot → Your plugin. So how do you trace it? Maybe #OpenTelemetry (#OTEL). Add it to #SemanticKernel agents, view with #Aspire, export to #Azure. ▶️ go.fabswill.com/OTELforAgents #Copilot

Peeked into #AgentSDK & WOW—so intriguing! 🧐 Swapped out my #SemanticKernel agents almost 1:1 w/ fewer configs! tested: ✅ Multi-step agents ✅ Legal-compliant feedback processing ✅ Smooth, structured real-time responses 💤 Time to sleep… if I can contain the hype! 🤣 #OpenAI is on fire 🔥
