Afternoon meetings…

Love and hate. Love when I have a few hours left before my usage resets & still 35% remains, because I can ask Claude for insane things. Hate when I have a few hours left before my usage resets & still 35% remain. Feels like wasted πŸ’Έ and not as productive as I could have been.

Every one of these started as a sentence I typed to Claude. "Make a film about all of it" was the last one. It made this. 12 apps + a few services in 7 weeks. What's your sentence? showah.co

53 hours. Not a bad 6 days for a side hustle(s). I have not come close to emptying my usage (primarily Opus 5.5)

I am currently watching Claude talk to a Microsoft support chat bot to resolve an issue for me. This is life now.

Why build an app when a 100 flavors of it already exist? Because I can. It's fun. Gets reps in. & my apps didn't talk to each other. That's it. So I built SPOT, where any record links to any other & Claude can add a task without me opening it via MCP. #buildinginpublic

Claude entering the personal bot realm... here we go.
We’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent. It comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf.

My entire feed is product releases. It never ends. I need to be content in always being behind.

We are moving from prompting AI to AI prompting us.

I want to consume 100% of my usage each week. I want to have plenty of usage remaining at all times. The eternal battle of the AI user.

I gave two models the same 31 customer texts. One was 7x faster. The other got 215 of 217 answers right. I'm keeping the slower one. Here's why:

Haiku: 99.1% correct, 1.45 s per message Clairic: 91.2% correct, 0.19 s per message Clairic nailed times, amounts, names and phones. It slipped on weekday math, and it followed an injected instruction with 100% confidence.

The confidence score worked: answers above 0.9 were right 79 of 82. Clairic first with Haiku as backup looks promising. Caveat: made-up data, one run. I'll redo it on real messages. #AI #Automation

Words or phrases that are overused since AI took off this year? I will go first. 1. bottleneck

Sometimes I feel like I have barely clicked Enter in my prompt to Opus or Sonnet 5.5 & it is already replying. The models continue to amaze me.

X post peeves 1. β€œBe honest” or β€œunpopular opinion”. AI or human slop & a waste of space. 2. Dogmatic proclamation about what others should do. Tell your story. Don’t write other people’s stories.

"Check out this app I 1 shotted"... No need. I know it sucks.
