Introducing Claude Fable 5.2 and Claude Mythos 5.2, designed to tackle the most daunting technical challenges.
They’re capable collaborators on ambitious projects in many fields, and show improvements in areas like coding, reasoning, and vision.

In Budget 2026, we’re cutting Canada’s marginal effective tax rate on new business investment from 13% to 6.4% — the lowest of any major economy in the world.
That means businesses, large and small, can deduct the full cost of most new investments.
Making Canada the best place in the world to build.

We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math.
It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training.
We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵
Blog: rikiyat.github.io/blog/weigh…
Readers added context they thought people might want to know
LLM was given weights explicitly as text in prompt and used code/forward passes (per authors' logs) to ablate Qwen looping direction, a known thinking-mode issue per model card. Primarily fixed repetition in that mode, not general 'natively' improving weights/math.

Introducing Gemini 4 Carbon, it's a big jump over Argon which we released just 2 weeks ago.
Gemini 4 Carbon is SOTA on cyber, long horizon tasks, ranks #1 on Artificial Analysis V5, significantly improves on usability in domains like coding, and is more aligned.

This morning, I spoke with Premier @ABDanielleSmith about the results of yesterday’s vote.
Over the past 18 months, our governments have worked together to deliver on what matters most to Albertans. Now, we have an opportunity to build on that progress.
Albertans have chosen Canada, and we’re moving forward together with renewed purpose and high ambition — to build a stronger future for all.

We’re bringing the magic of Waymo to Toronto! 🇨🇦
In the coming days, you’ll begin seeing Waymo’s all-electric vehicles driving through Toronto’s streets as we lay the groundwork for our ride-hailing service.
Our goal is to begin serving riders in 2028.

really enjoying using Argon. it's the best writing model in my experience. very useful for learning, explaining things and such.

Some rumors I've heard. I'll start with Google, then Anthropic and OpenAI.
Google: Insiders say Google has either cracked RSI (recursive self-improvement) or is very close. Their pace has picked up fast in recent months. They went from GPT-5 level to Opus 5.5 level in months, and speculation is that RSI made that possible.
Anthropic: About a week ago, Anthropic started a new pretraining run. It is not Fable 5.5 but what would become Fable 6, or something bigger, to catch up to OpenAI's Bel.
OpenAI: Bel (it may have another codename) is the model behind the math results OpenAI published a few days ago, and RSI apparently helped there too.
From what I'm hearing, OpenAI, Anthropic, and Google are all very close to cracking RSI or already have. It will get scary and exciting at the same time.

It’s feeling really magical inside of Shopify right now. It’s clearly the greatest time in the history of tech industry right now. I hope it feels similar everywhere else.

I love these guys!
@Shopify: first job out of college, $SHOP changed my life. I remember early days working with braintree in billing team lol.
@dhh: first framework I fell in love with. ruby on rails.
@bryan_johnson: best cult ever!

People seem shocked that the author of Clean Code doesn't read code anymore. But that should not be surprising.
Why did I write Clean Code? What is the goal of keeping code clean? To get it out of the way of the real job -- thinking.

I was paying almost $300/year for a YouTube research tool that shall go unnamed.
The product was getting too complicated so I decided to check if Claude can build the core feature set that I actually needed.
Claude built it in 5 min. 🥹

Been running a beta version of Campfire rewritten in Rust today! The code itself is still ugly as sin, and 6x as verbose, but the conversion was free*, and I never had to look at the Rust directly, so this is awesome 🤩 github.com/basecamp/once-cam…
