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
GitHub - fabianwilliams/agent-local-evals-starter: Comparative evaluation framework for agent implementations using local models and evaluation systems with comprehensive tracing and observability

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.

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.

Agent-First Commerce: I Built a Website That Sells Like a Sales Team
Over a weekend, I built and tested a working Agent-First e-commerce demo with Claude Code, MCP, and conversational checkout. Here's what I learned.

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.

🚗💻 Took #ClaudeCode Pro for a real dev spin this weekend. No toy projects — real repo, real tools, real #observability.
💡 Learned a ton about agentic workflows, #MCP, #OpenTelemetry, & Claude limits.
Would I do it again?
Absolutely.

Big fan of #LennyPodcast — it’s reshaped how I think, build, & ship.
Almost done with Click (🔥) and just started Good Strategy Bad Strategy (from #Anthropic cofounder’s rec) & yes laptop screen wide open ☺️
Thanks, @lennysan.bsky.social

📚 +1 for strategy + product craft.

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?

I don’t think given the photo what I’m making for today’s Sunday dinner… doing it 2X as well as I’m in the mood for leftovers #SteakAndAlePie #pasties during this upcoming internal engineering #FHL week to close out the fiscal year!

Change of pace today! Working out of #Microsoft #DC office or should I say #Arlington / #Rosslyn office today, after a sprint of back to back to back meetings, finding a quiet place on the Penthouse level for lunch at albeit 1430 hours! Later on there a #BAM event here tho’ ☺️

So... #MSBuild 2025 ended and I couldn’t stop thinking about #NLWeb & Observability
So I built this 👇
🧠 Real-time viz stack for devs
⚙️ #OpenTelemetry + Aspire

What telemetry would you want in a tool like this?
#NLWeb #Aspire #DotNet #Developers #GenAI

Can’t be in Seattle for #Microsoft Build so headed to the DC office for the watch event! If you are there in person & are building #AI solutions with #Microsoft365 data please grab me for a chat! I’d love to hear your scenarios and help where i am able! #MSBuild #Build2025

🔍 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.

🧪 Just built EvalRunnerAgent — a C#/.NET tool to test LLM output vs. #groundtruth using #embeddings.

✅ Works with OpenAI and Local Ollama
🧠 Cosine similarity scoring
📂 Outputs JSON results

I’m find myself tonight thinking about… #LaplaceDemon
it imagined a theoretical intelligence that, if it knew:
•The exact location and momentum of every atom in the universe,
•And all the laws of physics,

Then it could predict the entire future and reconstruct the past #AI #Determinism

Im thinking if I did this & demo/video shared my journey & shared almost all the code 😊 no one will get angry right? 😆I wanted to level up my game in @AnthropicAI #ModelContextProtocol & #AgentToAgent using #MCP & #SemanticKernel #CAPs so over the past nights & weekends I did this...
