o3 and Claude give me analytics superpowers as a founder. I can do in an afternoon what would have taken me a week 3 years ago. I put our database schema into context and it can write sql queries for any question, I run the queries, and the models can analyze / visualize the resulting CSVs.

Is it just me or do a lot of SWEs have a findom relationship with Claude Code and Cursor?

Happy Valentines Day! I made a social network for sharing what you love... and what you hate! Made with o3-mini-high in websim. Post here: websim.ai/@rob/lovehat...

Why do I still remember the password for my email address as a 10-year-old? Is that just taking up space in there? Is it load bearing?

My dog had a nervous breakdown from me watching a show with a fire alarm beeping without headphones on. These guys used to be wolves, what happened???

With Deepseek R1, I'm really feeling my preference switch to reasoning models. I'm also using Flash 2.0 Thinking over Flash in Websim. Comparing responses between Deepseek V3 and R1 really sold it for me. Wayyyy more depth to what's going on with R1.

I think the novelty of reading the thinking for Deepseek R1 is gonna grow old pretty quick and people will go right back to ignoring 90% of the text the AI produces

Generally just trying to route all of my personal LLM usage to Deepseek R1 over the next couple of days to get a feel for it. As a chatbot, it feels insightful, dutiful, creative, and extremely thorough. CoT is super cute, often more helpful than the answers.

Big takeway from the Deepseek R1 launch is that the visible CoT is super endearing

I actually think regardless of benchmarks, Opus 3.5 would be substantially better than Sonnet 3.5 bc it could understand more instructions all at once, whereas websim users have gotten into the habit of giving Sonnet one thing at a time.

My cousin in college told me he’s gonna get a ChatGPT Pro membership because “if I can’t make more than $200 a month from 20 second Sora videos I’ll cancel it.” Never been prouder.

It’s exceedingly obvious to me that we should make skilled immigration as easy as possible. Why wouldn’t we want talented people making money and paying taxes in the states? What founder wouldn’t want to be able to choose talent based on skill over location of birth?

Anyone know of an email client that represents threaded email really well? Finding it kind of hard to search for specific emails and track conversations that branch off in a bunch of ways.

The Gemini 2.0 Flash demo where you show it your computer screen and talk to it is awesome in concept, but whatever the system prompt is, it's annoying. It mostly narrates what it's seeing and hearing, like a toddler. Doesn't engage with the material. aistudio.google.com/live

Thinking about how Vegeta first reached Super Saiyan by leaning into his ego and entitlement. The idea that Goku could do it but he couldn’t made him so angry that he surpassed his own limits and became a Super Saiyan.

The framing of “abandoning” feels off to me, given that they likely repurposed a lot of the sensors, cameras, and computer vision to the Vision Pro. I admire that a lot about Apple, actually: it’s also probable they first developed “audio ray tracing” for the AirPods.

Ok now that OpenAI is back together I would really like for other AI labs / startups to release APIs for models that are anywhere near as good as GPT-4 so I’m not so dependent on them. I’d just like more serious, out-of-the-box working competition.

Dog owners, I have a problem. Bennie's **highly accurate** internal clock says that his first dinner is at 5:00 pm, and his second is at 9:00 pm. His clock does not recognize daylight savings time. He's sulking. Would you feed him an hour earlier to satiate the beast?

I’m not an AI Accelerationist, but I do find it impossible to imagine fixing all bugs and exploits ahead of time, before deploying to users, for pretty much any software, much less something as intuition busting and complex as AI. E/acc nah, but definitely not a doomer.

Semantic search is awesome, locally generated embeddings aren't much worse than OpenAI embeddings, and I doubt HyDE requires more capabilities than models like Mistral 7b. All together, I can picture intelligent knowledge management tooling that keeps all data on device

I wish more RAG and Agent apps would let me point at stuff on the screen. Like highlight text or draw a rectangle on the screen, and say "hey, change *that*" or "search for things like *this.*" Don't make me type everything into a box, let me point at stuff.

I think DALL-E 3 misspellings are cute tbh. Last year it couldn’t even get letters. It’s growing so fast ❤️ (images are propaganda for water lol)

Most people never revisit their notes. They make decisions and come up with ideas based on recent memory, vs. a lifetime of experience and insight.
Photo of a modern office setup with a computer monitor displaying multiple digital notes and documents. As they are being viewed, they start to swirl and distort towards a black hole that appears at the center of the screen. Around the desk, other physical notes begin to levitate and spiral into the monitor's black hole, symbolizing the unstoppable pull of the void.

It would be OP but if I could cast any Baldur's Gate 3 spell IRL, "guidance" would be high on my list (besides ones that would let me heal anything for anyone once per day, ofc). Just imagine having that extra 1d4 on all of your ability checks 🤯

I'm hoping for user generated labels outside of moderation purposes catches on, turning Bluesky into more of a community curated knowledge graph.

Aside: I like how this version of the meme does not have an IQ bell curve in it. To me, the image evokes someone trying to level up from their simple system, struggling to hold a bunch of moving parts together, and then defaulting to the simple system with what they learned.

People can always choose to use your product, an alternative, or nothing at all. When you're acquiring new users, you are competing against whatever they were doing prior. In this piece, I discuss how we can lower the risk of user default. newsletter.robhaisfield.com/p/competing-...
