Here are some of the people that I have learned from over the last few months/years.

This isn't everyone, but it's a great starting point if you are interested in AI, software engineering, or local hardware.

Later, I want to share more underrated people I missed. Please comment anyone you think I can learn from, and I will be sure to follow them! 🙂

Software Engineers (Super technical)
@webdevcody (Super technical in-the-weeds engineer)
@poteto (Unlimited AI usage but very cool skills)
@mattpocockuk (Very technical engineer and architect)

General AI knowledge and amazing tips
@MarkKashef (Amazing skills, tools and workflows)
@MatthewBerman (Very consumer AI tips but no BS)
@BetterStackHQ (More software than AI but some very good lessons)

Local Hardware and AI engines
@0xSero (Pushing local hardware)
@ashxhart (TensorFold)
@RaidOwlTweets (Homelab and networking)

Local AI
@bertholomusai (Very underrated local recipes)
@plotarmordev (Very cool niche models and config)
@MiaAI_lab (The Local AI Goddess)

I think we should collectively sign out of our tailscales… feels like a legendary attack surface

AI just helped find a bug in PHP, the code behind roughly 7 in 10 websites.

Governments in Finland and the Netherlands took sites offline. OpenAI shipped a free checker.

I ran it on a site I know is exposed. It said "unknown."

Here's how to actually check yours 👇

@thesamparr highly recommend you move over to a stack on cloudflare + astro; no honour in staying for the sake of familiarity/loyalty

One of the biggest perks of dictation apps is that they force you to enunciate.

When they mess up, it’s usually because I got verbally lazy, so they double as passive speech training.

They also made me realize I can optimize my “value per token spoken.”

If you ever saved an API key in opencode's console, do two things tonight.

Delete it at the provider (claude, openai, google) and make a fresh key for each app

Then set a monthly cap and a usage alert, so a stolen key tops out at $20 to $30

I'd rather lose $20 than wake up to $400.

GPT 6.1 Sol + Ultrafast is elite for hot fixes to anything.

I can finally use it without erasing 10% of my usage in one shot. Better.

Most marketers are still playing copy/paste and renting their workflows one AI subscription at a time.

- AI writers
- SEO tools
- Vibe coding tools
- "Content assistants" that are ChatGPT with a new logo

Monthly AI subscriptions = renting your workflow.
Claude Code + your own systems = owning it.

That's how I run a six figure agency solo. And I don't know s**t about coding.

So I'm breaking it down at the AI Practitioners Summit.

My session: Claude Code for Marketers Who Don't Code.

I'll open up my actual Claude Code setup and walk through the skills and marketing workflows I run on it. You'll leave with a setup you can use the same day.

Excited to speak with other high-level AI practitioners like @MarkKashef, @alexadark, @cole_medin, and several others.

@IndependentEco night and day!

I spent most of this morning screaming at Claude and thought the 5.5 honeymoon phase was over... until I realized I accidentally picked Opus 5.

What a horrific model that was.

If Fable is a huge step up from Opus 5.5, I think I'll have to get another Max plan.

It's been magical to build for the past two weeks.

I feel like I can do anything.

[Mark Kashef @MarkKashef]

@thisishars It’s unlocked so many ideas

[Mark Kashef @MarkKashef]

@alexandrekerner Extra high on tasks with one set of inputs and many outputs (eg short form assets) is epic

I’m usually team high though

[Mark Kashef @MarkKashef]

Opus 5.5 on xhigh 😮‍💨
