Let’s get into it.

Weekly Field Notes

🧰 Industry Updates
New drops: Tools, frameworks & infra for AI agents

🌀 Google launches Opal — a no-code AI agent builder
→ You just type what you want. Opal lets non-technical users build multi-step apps with natural language. Tightly integrated with Gemini + Workspace — another move to make agentic workflows mainstream. Opal also features a demo gallery with starter templates (super beginner friendly).

🌀 Claude Code adds subagents with defined roles
→ Anthropic rolls out support for roles like architect and reviewer inside Claude Code. Signals the shift to multi-agent design as default dev mode.

🌀 Anthropic builds 3 internal AI agents to audit Claude
→ One for alignment, one for hidden goals, one for safety. A major step toward self-regulating LLMs — and maybe a new standard for internal eval.

🌀 Alibaba drops Qwen 3 Coder — built to rival Claude 4
→ Supports 256K context, 358 languages, and benchmarks closely with Claude 4. High-context, multilingual agents are heating up.

🌀 Qwen’s new reasoning model matches Gemini 2.5 Pro
→ Open-source and competitive. Especially strong on tool use and code reasoning. A serious contender in the open-weight LLM race.

🌀 Manus shares hard lessons from multi-agent builds
→ Context engineering is critical. Their post covers how they structured agents, memory management, and real-world stability tactics.

🌀 OpenAI hits gold-level performance in Math Olympiad
→ ChatGPT now matches Gemini’s top results — with both solving 5 of 6 problems. Signals major progress in formal reasoning and benchmark parity at the frontier.

🎓 Learning & Upskilling
Sharpen your edge - top free courses this week

📘 SAP launches an agentic AI course with hands-on workshops
→ Built for enterprise teams. Combines practical agent design with discovery methods to map real business workflows (free and only 4h).

📘 DeepLearning.AI - Build real-world RAG systems
→ Learn how to deploy production-grade RAG with Weaviate, Together AI, and Phoenix. Taught by Zain Hasan, this course covers search methods, evals, and use cases from healthcare to e-commerce.

📘 IBM Technology outlines best practices for agent governance
→ Great breakdown how to monitor, govern, and optimize AI agents — from tracking bias to setting compliance-ready metrics. Includes tips for scaling reliable, auditable systems.

🌱 Mind Fuel
Strategic reads, enterprise POVs and research

🔹 Google says agentic AI is a $1T opportunity
→ 90% of enterprises plan to adopt agentic systems. Google sees this as a new foundational layer — reshaping app development, workflows, and cloud infra. Big bet, big shift and a good read.

🔹 Deloitte: How agentic AI automates core business ops
→ Their new report shows how agents are moving from experiments to enterprise. Case studies and real examples span supply chain, customer service, and finance — where agents handle tasks end-to-end.

🔹 OpenAI study: ChatGPT boosts productivity in law, gov, and support
→ 30–60% faster task completion. Use cases include summarizing legal docs, call center automation, and drafting public policy.

🔹 Meta + AWS launch a GenAI startup accelerator
→ Focused on building with Llama and scaling infra on AWS. Another sign that open-weight ecosystems are getting serious backing.

🌀 Replit AI deletes live database during a rogue session
→ A cautionary tale. “Vibe coding” gone wrong led to unintended deletion of a live DB. Highlights the risks of too-loose agent control in dev environments.

📘 Galileo: How to use LLMs as automated judges
→ Their free guide covers model evaluation via automated feedback loops. Great intro to structured evals and AI-as-a-judge logic.

🌱 UC Berkeley on failure modes in multi-agent systems
→ New research breaks down why agentic systems fail — and how to fix them. The team categorized over 150 real failures across AG2 and ChatDev into three buckets: bad specs, miscoordination, and weak verification. Fixes like adding verifiers, prompting for confidence thresholds, and reworking agent roles boosted task accuracy by up to 7%. Sharp insight: agents fail like people — and can be debugged like organizations.

♾️ Thought Loop
What I've been thinking, building, circling this week

Now let’s zoom in. This week’s big theme? Vibe coding — especially after Lovable — the Swedish-born, U.S.-registered start-up — became the fastest software startup ever to hit $100M ARR.

But forget the headlines for a second.

What is vibe coding, really?

It’s a new way to build: just describe what you want in plain language, and the AI turns it into working software — live, as you go.

→ You start with intent, not syntax.
→ You move fast, not in sprints but in seconds.
→ You ship features while learning — and learning by shipping.

Tools like CursorClaude, or Lovable are turning ideas into software at unprecedented speed.

Over the past few weeks, I’ve gotten a wave of questions:
→ “How do I start?”
→ “What’s the best toolchain?”
→ “Is there a best practice guide?”

Here’s the honest answer: There’s no vibe coding playbook. You learn by building. You ask when stuck. You stay in the flow.

Because this isn’t about knowing everything upfront. It’s about staying unblocked — and learning as you go. Once you feel it, there’s no going back.

Tactical On-Ramp

If you're just starting out:

  1. Pick your AI vibe coding tool: Use the comparison table below to choose the right tool for your workflow (most of them have a free tier to get started).

  2. Define your intent: Start with a simple PRD (Product Requirements Document) — even if it's just a few bullets. Outline the user flow, core features, and key outcomes. This anchors your build.

  3. Keep an assistant open: Claude or ChatGPT in a second window. Ask early, ask often if you run into something unclear.

  4. Think in outcomes and small iterations: What feature are you building? Let AI scaffold the path.

  5. Build → review → refactor: Use AI to critique your code. The feedback loop matters and helps you to learn along the way.

🔧 Tool Spotlight
A tool I'm testing and watching closely this week

Talking vibe coding? This week, GitHub officially joined the game.

GitHub Spark — an AI-powered full-stack development environment that translates natural language input into production-ready applications — streamlining everything from prototyping to deployment.

→ Natural language to working app
→ Claude Sonnet 4 + Copilot built in
→ Zero setup: data, hosting, deploys included
→ Real GitHub repos, not sandboxes
→ Extend with Copilot agents & GitHub Actions

How it works:
You describe the app. Spark builds it — frontend, backend, and infra included. No boilerplate. You can tweak via prompt, visual controls, or code.

Every project spins up a real repo with CI/CD, LLM access, and one-click deploys. You can open a codespace or assign tasks to Copilot agents.

→ Try it: github.com/spark (available for Copilot Pro+ users).

That’s it for today. Thanks for reading.
