Hey folks 👋

🧠 ANTHROPIC HAS ACQUIRED BUN

Anthropic has officially acquired Bun, marking its first-ever acquisition. Bun is a high-performance JavaScript runtime that makes JS code run dramatically faster — and behind it is one of the strongest JavaScript engineering teams in the world.

The story of how this acquisition came together is absolutely wild 🤯

Interestingly, OpenAI also recently acquired a company called Neptune AI, which builds tools for AI researchers. This clearly signals that major AI labs are now aggressively moving into infrastructure and tooling, not just models.

🧠 HOW IS AI CHANGING WORK INSIDE ANTHROPIC?

Engineers inside Anthropic now report being around 50% more productive thanks to AI. Even more striking, 27% of Claude-assisted tasks were projects that would not have been done otherwise. This shows AI is not only accelerating work — it is actively expanding what teams are capable of attempting.

🏛️ LESSONS FROM BUILDING AI AGENTS FOR MESSY GOVERNMENT PDFS

A real-world deep dive into the pain of working with broken, inconsistent, and poorly structured government PDFs — and how AI agents can be trained to survive chaos, handle noise, and extract meaning from structural disasters.

⚙️ WHAT I LEARNED BUILDING AN OPINIONATED AND MINIMAL CODING AGENT

A thoughtful reflection on creating a small, strict, and intentionally limited coding agent. Instead of building bloated frameworks, this approach focuses on clarity, constraints, and reliability — a refreshing contrast to today’s massive agent stacks.

A full-year experiment treating ChatGPT Pro as a real employee. The article explores productivity gains, daily workflows, unexpected limitations, and the psychological shift of working alongside an AI “coworker.”

🛠️ CURSOR’S GUIDE FOR NON-TECHNICAL HIRES TO BUILD WITH CURSOR

A practical guide designed for non-engineers who want to build real software using Cursor. It breaks down barriers between idea and execution, showing how code generation, debugging, and shipping can be done without traditional engineering backgrounds.

⚡ OPUS 4.5 RELEASED ON CLAUDE CODE — AND $1B RUN-RATE

Opus 4.5 is now finally available on Claude Code Pro plans ($20/month) 🎉
The usage limits are tighter than before — but access to this level of reasoning power is now open to a much broader audience.

Even more staggering:
Claude Code has already crossed a $1 billion annual run-rate, just six months after launch 💰
And according to industry rumors, Anthropic is preparing for an IPO.

This places Claude Code among the fastest-growing developer platforms in tech history.

🏗️ GOOGLE WORKSPACE STUDIO IS NOW GA

Google Workspace Studio is now officially Generally Available (GA) ✅

It’s positioned as an automation builder, but it clearly goes far beyond simple workflows:

  • Connects multiple apps (even outside the Google ecosystem)

  • Inserts AI steps between processes

  • Operates entirely through prompts

This signals Google’s push into agent-based automation at the enterprise level.

🤖 MISTRAL RELEASES LARGE 3 & MINISTRAL 3

Mistral has released several new models:

  • Mistral Large 3

  • Ministral 3

Mistral Large 3 now competes directly with:

  • DeepSeek 3.2

  • Kimi K2

However, what’s even more exciting is the Ministral lineup, which comes in:

  • 14B

  • 8B

  • 3B

Each size includes:

  • Base

  • Instruct

  • Reasoning variants

This makes powerful, flexible AI far more accessible for real-world deployment.

🌐 WHAT I’M CONSUMING
