It's pretty cool that we have founding engineers of internal products now. People would have healthier careers if intrapreneurs got as much social status as entrepreneurs.
If you like using Claude Code, you’ll really enjoy this conversation with @_catwu and @bcherny, the creators of Claude Code. They talk about how it started, how the Anthropic team actually uses it day to day, and how even non-dev teammates are now comfortable using the terminal.

We're so excited to launch Claude Code on the web and iOS app today! This has become a daily driver for many of us on the Claude Code team. Here are a few of our favorite ways to use it:
Introducing Claude Code on the web. You can now delegate coding tasks to Claude without opening your terminal.

The Claude Skills stuff demonstrates just how valuable it is for agents to just write more code. I'm very bullish on that general approach, even for non coding use cases.

Readers responded with both surprise and agreement last week when I wrote that the single biggest predictor of how rapidly a team makes progress building an AI agent lay in their ability to drive a disciplined process for evals (measuring the system’s performance) and error

Haiku 4.5 breaks the "cheaper means worse for agents" rule. We tested it head-to-head in @CoraComputer email assistant: it delivers Sonnet-style agentic capabilities at 3x lower cost and beats GPT-5-mini performance on speed. The premium mid-tier model actually exists now and
BREAKING NEWS: @AnthropicAI just dropped Claude Haiku 4.5 and it's 🔥🔥🔥 We've been testing it for a few days internally @every and here's your day 0 vibe check: - It's almost as smart as Sonnet 4.5—great at long-horizon reasoning and tool calling - It's faster than Sonnet

I use voice for ~70% of my writing (code and words) but I have to admit that I'd feel awkward in doing so around others. It activates all my "oh I'm bothering others" instincts
This is absolutely insane and proof that voice is about to transform the workplace. At Wispr, employees use voice hundreds of times a day to multitask across their entire workflow. Here’s one dev using Cursor and Gmail simultaneously, all through WHISPERING, on a $10 mic.

I tried to explain why I don't believe the recent accusations toward my former teammates, as well as how the Ruby and Rails Infra team at Shopify operates and why it can be trusted. https://t.co/cgRySjoVlr

I’ve been meaning to write a post about my perspective on Open Source and corporate entities. I already got the rough outline of it; however, I’m suffering from writer’s block, but more importantly,...

This is obviously based. Anthropic, don't change a thing
@LinXule @ESYudkowsky Yeah... this was from it misunderstanding something and the prompt was "be real". This is a mild example.

Claude Code pro tip: use the new /rewind command to roll back code changes instantly. Model messes up? no biggie, just rewind it back to when it worked!

We're also releasing upgrades for Claude Code. The terminal interface has a fresh new look, and the new VS Code extension brings Claude to your IDE. The new checkpoints feature lets you confidently run large tasks and roll back instantly to a previous state, if needed.

Why I'm not rushing to take sides in the RubyGems fiasco

We are in the midst of a Ruby drama for the ages. I'm sure a bunch of people figured we were all too old for this shit, but apparently we are not. This debate…

"Skylar, all the models I trained, I..." "If I need to hear you poisoned these minors with dophamine short-forms for the family one more time...." "I liked watching reward_normalized_teenager_engagements go up on wandb dashboard. I was good at it. I was... alive"
@ABAtanasov Imagine doing an entire PhD, having multiple NeurIPS/ICLR/ICML papers, a very high TC, and tons of respect… Only to end up working on the digital version of meth specifically targeted at minors and old people

When Claude Code fetches Bun’s docs, Bun’s docs now send markdown instead of HTML by default This shrinks token usage for our docs by about 10x
