Thanks! Try it out and let me know what you think.

It's still (really) early days for putting this together, and while qualitatively it's working well for me in my experience, it's by no means proven to work yet in plenty of cases.

So that's why I'm open-sourcing it! Hoping to see what y'all think of it. Bring on the feedback!

…and here's the response from Claude 3.7 Sonnet, which was also great.

Mixdown prompt example with complex prompt and variables

Mixdown prompt example with complex prompt and variables

The syntax allows for adding key:value pairs, which can then be used as variables within the prompt. This sets up a means to quickly swap out individual bits without reconstructing entire prompts.

Check out this prompt I sent (with nothing else) to GPT-4o (link in next post):

Sample minimal Mixdown prompt example

Mixdown is a syntax/technique for writing AI prompts that work well in most modern LLMs. In my experience it's been easier to create more complex prompts that return reliably consistent responses.

It mixes elements of XML (structure), YAML (data), and Markdown.

Anyone out there that's got some expertise in doing AI prompt evaluation? 🀞🏼

I've been experimenting with a new prompting technique that's showing promising results, but really want to put its through its paces.

Companies: Please, please offer an RSS feed for your blogs & changelogs.

So far I've tried to add feeds to my RSS reader from OpenAI, Anthropic, Cursor, and Warp, and none of them offer a feed of any kind. 😩

Why skimp on offering a feed? Is there a business reason to not to do so?

For sure πŸ’―. Was just playing it for son the other day and he was blown away. From Yesterday still hits so hard.

Wow this is great, and smart! I've been super impressed with Shapiro and am proud he's our governor here in PA. I'd hate to lose him in that, but would love to see him on the national stage. Dems could really use more like him.

Feeling truly unlocked in building things with AI. While coming up with things I can handle product, UI/UX, etc., I've always felt held back by my limited development experience.

Not anymore.

Going from idea " docs " code " working demo " deploy before was months. Now it can be hours. 🀯

Something like 20% of the coffee imported to the United States comes from Columbia. A 25% tariff on Colombian imports, let alone 50% would have a pretttty negative effect on U.S. consumers.


Nearly 3/4 of American adults drink coffee daily.

Wonder how people will feel once prices go up. And fast…

ChatGPT's Tasks feature is promising. But its iOS notifications really don't do it a service, because it's not using all of the fields it has access to.

If instead it used a short task name as the title and the result as the body, notifications would group properly and be 1000% more useful.

For each measurement I dictated, I had ChatGPT read it back to me, so that I could confirm it was accurate.

I’ve been burned plenty of times by trying to decipher my own chicken scratch on stuff like this, so it’s a major help.

Definitely going to do this more often for this and similar contexts.

Recently I tried using ChatGPT's advanced voice mode with my AirPods on to dictate measurements of a complex space in real time, and then calculate spacing, conversion, etc. It worked *so* well.

It was much faster, and probably more accurate than scribbling each as I measured.

I'm just a scale of 1 here, but it might be worth sharing a personal experience: I was denied multiple home loans because (under no uncertain terms) I had held and sold crypto, and my W-2 was from a crypto-related company.

Eventually I was able to get one, but not before a lot of hurdles…

Such a good one. Going way back to the aughts whenever I'd come to NYC I'd stay in the LES, with Meatball Shop, Idle Hands, and Marshall Stack on heavy rotation. Love that spot.

Can you share a bit more about what you’re missing? Would love to hear.

As far as the eye tracking APIs, I try to always consider β€œwhat’s the Black Mirror version” of a feature. In this case I imagine an always on tracker that’s there for advertising using literal eyeballs. See what people look at.

This is the kind of thing that @cloudflare.social could do really well. They should.

Raycast can do *so* much, and fast. Recently I tried something similar to what @chrismessina.me suggested, which was to give various commands aliases that began as a typical query.

"ac" launches the "Kill Process" command in Raycast, since I usually tried to launch "Activity Monitor" before. πŸš€
