Just cancelled ChatGPT Pro & Cursor Pro
Not getting $40/m value from them when I can use Gemini 3 Pro +Antigravity (with Opus 4.5)
I suspect many others will do the same. If Google can undercut price and offer the same product (arguably better), others need to exceed expectations to get me back

Yes, and many bad uses of computers too.

I started my substack this time last year when I had a few days off to think. I’ve had less to than I’d like in 2025 and that looks set to continue. I have a few ideas brewing but in the interim why not take a look at the post that kicked it off if you haven’t already 🧪

New blog post about a side project I've been tipping away at.
I've build an app to explore open-ended idea discovery using LLMs in a multi-agent evolutionary algorithm.
I've also open source the code so you can play with yourself

Codex in particular is very slick at inviting you to farm out lots of small tasks in parallel.
It's all very cool, but so far I'd only be comfortable with using it for very tiny, easily verifiable changes [I merged ~6/7 PRs of tiny fixes after about 5 mins work from me].

They're both asynchronous coding agents that spin up a VM to make changes, test them, commit them and create PRs. They discuss their changes, and show you nice diffs.
This means you can just use your phone if you like and code from ... anywhere.

Might be a lack of imagination on my part but my default expectation is for the $6.5bn acquisition on Jony Ive's io to result in OpenAI wearable pendant like the so many already out there (e.g. Limitless below)
Hopefully the was something more exciting in the deal.

I find this kind of science very exciting because it's accessible to those who can't build the models themselves.

I cringe when I see headlines from OpenAI leaders about "colonizing the light cone". They will probably continue to get very rich from monthly subscriptions. But it's the science led orgs like Deepmind that will change the world.

But Deepmind have been steadily closing the gap on the models front and are just in a league of their own on extracting real tangible value in Science and Engineering.

Yes, OpenAI are better at product and leaped ahead with their LLMs. I still prefer using ChatGPT to the alternatives.

Work like AlphaEvolve is what for me has always been the clear distinction between Google DeepMind and OpenAI. 🧵

Ok, thanks, recordings would definitely be appreciated. We're working on FM for Neonatal EEG so I'm interested to hear about other's experiences

😅 definitely part of it. But I think of it more a breakthrough in the crappy post training for prompting issue LLMs have. I wrote a bit more about it here if you're interested open.substack.com/pub/selfsupe...
