@sean_j_roberts @lutherlowe It's shocking how bad Siri has been for so long.

I had never used @ExaAILabs until 30 minutes ago. I saw @jasonlk's post, created a free account in 30 seconds, and connected it to @Muse.

In minutes it pulled state and federal DUI and crash fatality data and built charts. (I'm in the alcohol monitoring space.)

👉 California DUI arrests: 366,834 in 1990 → 124,141 in 2019. Down 66%.

👉 In 2024, 912 of California's 3,876 road deaths were in crashes where a driver was at .15 BAC or higher -- nearly 2x the legal limit.

Pretty incredible to have vast source data paired with an AI agent.

[Jason ✨👾SaaStr.Ai✨ Lemkin @jasonlk]

Our agents use a LOT of Exa

For us, it just covers all the gaps. The gaps all the APIs and enrichment services we use for our agents don't cover.

It's relatively cheap, so we basically run it unmetered (like Jev now, too)

Something cheap enough to run unmetered 24x7 = something really big

Especially if your agents use it all day and night long. As our agents do.

We got the Bambu P2S for my son's 9th birthday this past June and it's been great so far.

Somehow we printed a sweet collapsible sword. The mini castle is a small test print of our much bigger 'vibe-manufactured' castle; we used Opus 5.5 and only a prompt to create the printable file.

@BillDA @LPInvestor Medical, tax, and legal. If you are not using a frontier model as a partner in reviewing the work product, that's a huge mistake.

Fable found a serious prescription error post-ER visit for me.

@AlexFinn @kristaletz @bot @bot send them to me too.

Someone discovered a new Amazon AI feature that summarizes what it knows about you and I am crying of laughter

[Keith Nothacker @knothacker]

@btaylor @Meta @SierraPlatform @Genesys @instinct @RocketOTD @Shopify @stripe @Walmart Interesting that Amazon is not on this list.

Cool fog day in San Francisco today.

@jacob_posel I'm in for the seed round. 👋

@nikitabier @jonoringer Please write an insider account of your time there. The people demand it.

We are now entering into an era where any product can be created exactly to a consumer's preferences & needs.

I vibe-fabricated a dog door with a wifi-controlled lock, perfectly to the specifications & design of my house.

I know nothing about metal fabrication or electrical engineering.

It's now getting manufactured and delivered in 2 weeks -- for almost the same cost if I bought a mass-produced item off-the-shelf.

Two years ago today this man told us "I will cripple you" (referring to the entire U.S. economy) if we didn't give his east coast port union workers what they wanted (60%+ wage increases and a pledge of no automation of our ports). It worked btw, he got all his demands.

[Keith Nothacker @knothacker]

@Seanfrank @seanmcginnis Amazing work, thank you.

I used GPT-6 Astra to break an unsolved cipher to one of Napoleon's generals that had gone unread for 217 years.

What makes this impressive isn't actually the codebreaking, but that Astra completed the entire multi-modal workflow in ~6 hours from a single image and goal.

2019: “GPT2 is groundbreaking in two ways. One is its size, says Dario Amodei, OpenAI’s research director. The models “were 12 times bigger, and the dataset was 15 times bigger and much broader” than the previous state-of-the-art AI model” https://t.co/ytFQEdQ2YZ

[Keith Nothacker @knothacker]

@OpenAI This is an incredible marketing video.

[Keith Nothacker @knothacker]

@michaelpatron0 Amazon should thank you for calling out their mistakes. It shouldn't take viral X posts to resolve this type of fraud.

[Keith Nothacker @knothacker]

@michaelpatron0 @amznsellerhelp Absurd. I would tag Andy Jassy but he's already blocked me for reporting fraud like this.

Today I installed Grok @bot. First impressions:

- I really like it.
- It's fast.
- It goes above and beyond the call of duty on most answers in a way that felt different from other AI platforms.

As background, I use @claudeai Fable 5 with Cowork nearly every day for business (Team) and/or personal use and love it. I have @openclaw. I'm not a software engineer but I hacked around with Claude Code enough to build https://t.co/BIwTapZeKL (hobby project).

To test Grok @bot I asked it to analyze my performance in yesterday's Double Dipsea trail run in Marin. It not only pulled my results, but pulled full results for all 421 finishers - names, ages, splits, hometowns, etc.

From there it told me things about my performance that I would have never known:

- how rare negative splits are across the field (faster second half race time vs first half): only 4% of runners ran a faster second half in the race than their first half.
- how many people I passed in the second half (42).

I didn't ask for charts but it made great charts! In fact my prompts were basic, short, and generic. Grok @bot outperformed expectations by a mile.

Impressed by the comprehensive Dipsea analysis, I spun up a 'CEO Advisor' bot. It pulled so much public data about BACtrack so quickly that I thought it somehow had access to private data; no, it was just really good and fast at incorporating public data into answers. It then recommended making a key hire for one of our divisions, had me sign into my LinkedIn account through a virtual Chrome browser, and then identified 10 great candidates. Not bad candidates, high quality, great candidates with directly related experience. It was fast!

I didn't want to get excited by a new AI platform but I am. Nice work @bot team.
