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!

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

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

If you use #LinkedIn I have a #POLL running asking about the #ROI or #Value of Technical Deep Dive Level 300+ sessions at Conferences here linkedin.com/posts/fabiangw… & if you are on #Reddit consider responding there reddit.com/r/polls/commen��� Thanks & less than 2 days before closing thanks 🙏

you are the 1st but thanks for trying it.. adding to backlog.. if you click the button what happens? works?

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.

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.

Claude Code Pro Weekend TestDrive Real Dev, Real Repo, Real Observability with MCP and Agentic Flows Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

🚗💻 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.

Tracing your AI agents?
You should.
I just dropped a full real-world build:

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?

And 2 pasties … couldn’t resist… #SteakAndAlePie

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!

Not sure but will look at my calendar, it’s not my regular office but I do come on time to time for meetings or to meet up with work colleagues

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’ ☺️

Let’s see what the fuss is all about #ios26 #watchOS26

💡 Learn about advanced considerations for M365 Data with Copilot Agent Plugins (CAPs)!

Let @fabswill.bsky.social show you best practices and key insights for extending Microsoft 365 Copilot with plugins.

We’re holding on my a thread lol for events to do together ask @melihubb.bsky.social ha ha

All the time, OneDrive keeps reminding me and your DC spot keeps popping up lol

I miss our cookouts ☺️

Unlocking Developer Observability: NLWeb + OpenTelemetry + Schema.org Traces (🚀 Fresh after MSBuild) Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

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
go.fabswill.com/OTELNLWebDemo
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.

▶️ go.fabswill.com/OTELforAgents
#Copilot

They know how to keep the game going…. Now I have to see how far I can carry this lol 😂
