Microsoft releases NLWeb NLWeb uses MCP to make it simple to interact with websites in a standardized way. Devs can now convert any website into an AI app. MCP is to NLWeb what HTTP is to HTML. This went largely unnoticed this week, but it looks like a big deal.

Cursor now supports 1M context-windows, the most expensive models, and unlimited tool calls with API pricing.
How do you think we should be pricing for very expensive models (o3) or ultra-long context windows (~100k LOC) in Cursor? API pricing, higher subscription tier, something else?

today we are introducing codex. it is a software engineering agent that runs in the cloud and does tasks for you, like writing a new feature of fixing a bug. you can run many tasks in parallel.

🧵Google DeepMind just dropped a bombshell: An AI agent that autonomously writes algorithms better than humans. It’s called AlphaEvolve, and it could completely change how we build software and solve problems. Here’s why this changes everything👇

AI SDK 5 concept: loop until condition Often you want flexible control over when the steps loop stops.

🔥 🤖 🎥 SURPRISE LAUNCH: GPT-4.1 now available in ChatGPT if you haven't tried it yet because it's only been available via API, I recommend you try it... it's different. 🎯 here it is searching the web and explaining how to generate an MCP Server from a natural language spec along with code

DSPy’s “value prop” is simple: If you stop writing prompts and instead write Signatures, you gain access to an ever-improving repertoire of algorithms (Modules and Optimizers). You also future-proof your AI system: you stop tinkering with the stuff (like specific prompts) that will get washed away in a few months—and you focus instead on the information flow fundamental to your application. DSPy isn’t “hard”. There’s a learning curve to doing proper software design for AI. Skipping DSPy doesn’t make those principles go away. The principles are below:
For AI software: 1) Information Flow is key 2) AI steps should be functional and structured 3) AI behavior specification should be decoupled from inference strategies 4) … and decoupled from learning paradigms 5) Natural Language Optimization is a powerful learning paradigm

Automating stuff with a human in the loop is 10x harder than it looks. Automating stuff to where it has no human in the loop is at least 1,000x harder than it looks

You can now connect GitHub repos to deep research in ChatGPT. 🐙 Ask a question and the deep research agent will read and search the repo’s source code and PRs, returning a detailed report with citations. Hit deep research → GitHub to get started.

Gemini-2.5-Pro-preview-05-06 is now my top coding model. It beats o3 and Claude 3.7 Sonnet on several of my hard prompts. One example prompt: "Code simulation of water in a bucket that is rocking back and forth." See how it crushes o3 and Sonnet. Google, call it Gemini 3!

A few things to note: 1. GenAI tools will result in *far far more* software produced than before 2. The more agentic the tool, the more it will generate (vs autocomplete) 3. "Accepted lines of code" does not mean
Cursor writes almost 1 billion lines of accepted code a day. To put it in perspective, the entire world produces just a few billion lines a day.
