I’ve said it before and I’ll Say it again..

Anyone saying AI is going to be going up in price or slowing down etc is just wrong.

The competitive market surrounding AI is just going to keep making it faster, cheaper and more intelligent.

Previewing Ultrafast mode: GPT-5.6 Sol at up to 14x the speed.

Launching first in the OpenAI API to a select group of customers with expanded access to more businesses as capacity grows.

@AWSSupport That’s great, thanks for the update. Although spending the last hour 💩 myself hasn’t been fun 🤣

[Karl Hewitson @KarlHewitson]

Anyone know how to get in touch with AWS support?

They have kindly just told me via email that I’ve gone over my monthly $15 budget… by $467,100,415.82 😳

Feeling slightly sick. 🤢

We are about to see the biggest jump yet in ability, speed and reduction in cost for open weight Chinese AI models.

While the US restrict access to their closed source state of the art models, you can bet the competition from the rest of the world will push as fast as possible!

[Karl Hewitson @KarlHewitson]

This is possibly the most impactful and important invention I have seen for years.

This could change healthcare forever!

[Karl Hewitson @KarlHewitson]

To understand how much of an issue the AI world has right now, just look at how few posts have come out from Anthropic & OpenAI since the US Government forced the restrictions on Fable 5

Posting almost daily, to radio silence. Bet there's some interesting meetings taking place

@sama Will you be doing anything to minimise the risk of your AI models being used to automatically fire weapons against humans?

[Karl Hewitson @KarlHewitson]

Remote control for Claude code is an absolute game changer.

Not just because of what it does now, but where it’s leading.

Forget openclaw, this is the reason to buy a Mac mini 🔥

Managing backlogs and tasks across side projects and managing multiple running terminals & agent stacks is complicated and things get missed.

I built https://t.co/kD2xZlRkYn to fix this for my own use.

Figured it can help others so have published it free.

Works with Claude code, codex or any other CLI coding agent without needing API keys or extra costs.

Built with rust so it’s lightning fast and doesn’t use loads of memory or cpu.

Have a look at https://t.co/kD2xZlRkYn

I did the same as you and didn’t think they worked the way I wanted so built a desktop app to do what I wanted.

Instead of worktrees and diff views, it focuses on managing your backlog and planning, alongside the agents.

You can also manage your knowledge packs, notes and files so it’s less about git and diffs and more about what matters.

@kris Your site has a bug in the registration flow. I logged in and selected handles for me and my AI. The page crashed then when I tried again it said the handles were already taken.
Looks like you’re marking handles taken before locking them to an account.

[Karl Hewitson @KarlHewitson]

My new favourite dev workflow: spec & build with Claude Code → review with Codex → iterate. Repeat.
Used this approach to build Concursus - a desktop backlog manager with in-app AI agent terminals.
Then used it to manage its own backlog.

On December 8, the Perseverance rover safely trundled across the surface of Mars.

This was the first AI-planned drive on another planet. And it was planned by Claude.

[Karl Hewitson @KarlHewitson]

One of the things I’ve loved over the last few years is seeing more and more new technology that really makes you sit back and say wow.

So many advances in AI and amazing tools built around them.

The most recent wow experience was Claude code + remotion. Wow!

If you’re doing mass outbound emails, piece of advice: test before you send.

Nothing stops you using a company quicker than receiving an email for %firstname% or %company_name% 😂🤦
