Deciding with LLMs

Responding to the decision model hype train

The decision model hype train has reached fever pitch. Fair enough, they're not a bad idea: we had machine learning classifiers long before autoregressive transformers turned up.

Reasoning effort

Performance or autonomy?

A little while back Anthropic put out a tutorial, Choosing the right effort level in Claude Code. I've been chewing on it ever since. Effort level high, you might say.

Opus 5.5

A new GOAT in town

It has been mildly upsetting to me that Anthropic had been lagging behind OpenAI in a few ways that really matter. Primarily price/performance at sensible effort levels. Performance here crucially including speed, and price being more accurately, how much you can get done with a sensible subscription.

The endangerment of lazy work

The consequence of AI doing a decent job

If you look around here you'd probably form the view I'm your typical bullshit AI bro. I guess by some measure I am but in many ways I find the most interesting thing about AI is what it means for us.

Time to make some space

For some to rise, some must fall

I think it's about time to remove some older experiments that have run their course given I have a few incoming ones. Each one of them costs money to run and there's a couple of them which I don't think 'earn their keep' as Claude would say. Top candidate for the chop is the spine-o-meter.

An image model test?

Image model competition is heating up

I find the wallpaper a constant source of joy. Looking at my phone after 10AM and seeing what interesting new take on the daily news appears. The only thing I think I'd like to change is to shift the sources of news inspiration away from the AI bro news which is, frankly, all a bit one-note, is it not?

Deep Dive V2

An exercise in overcomplication

Last post I suggested that a light Deep Dive refresh was on the cards before the Juggler experiment. Yeah, so it's done but my word it was a rabbit hole. Over many iterations I gradually sharpened what I wanted. Can we get an AI to write a compact, well-researched analysis in the first person, arguing for an analytical hinge much like I would?
