Building AI apps

[Paul Vu @PaulVuAI]

Google's free 5-day AI agents course. build this after day 5:

1. pick one task you repeat weekly
2. spec it as if briefing a human
3. use Claude Code to build it
4. test with real data, not mocks
5. ship it — even broken

the course is theory. this is how you build instincts.

[Peter Yang @petergyang]

Google's free 5-day AI Agents course is back, and this time it's all about vibe coding with agents. The last one had 1.5M learners.

Here's what the course covers:

→ Day 1: Agents + vibe coding. Build agents with Google Agents CLI and your coding agent.

→ Day 2: Tools + interop. Connect agents to external APIs and each other.

→ Day 3: Memory + context. Give agents long-term memory and personalization.

→ Day 4: Quality + security. Add testing, guardrails, and evals to improve reliability.

→ Day 5: Prototype to production. Deploy and monitor your agents.

It's 1-2 hours a day, taught by Google engineers, and (best of all) free 🥹

client burned $500M on Claude. the checklist:

1. set per-user limits in Anthropic console
2. cost per feature, not per run
3. hard spend cap, not soft warnings
4. test workflows on dev budget first
5. weekly AI cost reviews

never a model problem. always process.

AI consultant reveals a client accidentally spent $500,000,000.00 in a single month after failing to set employee limits on Claude usage

[Paul Vu @PaulVuAI]

100+ parallel agents is the new normal. how to use it:

1. /effort ultracode
2. /goal with clear success criteria
3. subagents handle research + code + tests
4. step in only when they need you
5. ship it

solo prompting is the old way.

[BridgeMind @bridgemindai]

UltraCode is running over 100 Opus 4.8 agents right now.

This is the future of software development.

Not 5 agents. Not 10.

Over 100 working simultaneously across the entire BridgeMind ecosystem.

This is what vibe coding looks like at scale.

One person orchestrating a swarm of AI agents building, debugging, and shipping in parallel.

We are so early.

@muiz_rexhepi claude code for architecture and logic, v0 for fast UI components — the combo is hard to beat. one understands your whole codebase, one generates components fast.

@DeRonin_ the zero check-in part is the real trust fall. first few times i kept coming back every 15 mins. now i actually leave it alone — and the results are way better for it.

[Paul Vu @PaulVuAI]

@_MaxBlade just ran ultracode on a side project — left it for 90 mins, came back to a full refactor with tests added. the part that still surprises me: it improved things i didn't ask it to.

[Max Blade @_MaxBlade]

your one job today is to open opus 4.8

set /effort to ultracode

ask it to make your app 100x better in everyway

Which of these is already in your workflow?

🧵 5 AI drops this week that changed what's possible:

(models, tools, workflows — the ones builders are already using → thread 👇)

[Paul Vu @PaulVuAI]

5/ One prompt → whiteboard explainer video in 20 seconds.

Voiceover, animation, visual flow — fully automatic. No timeline, no editing.

Content creation just got a serious shortcut.

[Paul Vu @PaulVuAI]

Claude Code killed the agency design loop:

1. input: brand URL + product name
2. output: 6 finished IG carousel slides
3. no Canva, no brief, no back-and-forth
4. agencies charge $2K for this

if you're still briefing designers for social content, this workflow has lapped you.

[Mike Futia @mikefutia]

I just built a branded IG carousel generator in Claude Code 🤯

One brand URL + one product name = 6 finished carousel slides.

The kind an agency charges $2K to produce.

All inside Claude Code.

Perfect for DTC brands, agencies, and mobile app operators who need on-brand social content without briefing a designer or waiting a week for revisions.

If you're building IG carousels manually — writing copy in Notion, designing in Canva, exporting slides one by one, going back and forth with your creative team for days...

This tool eliminates the entire loop:

→ Drop in a brand URL and product name
→ Claude scrapes the site and extracts colors, fonts, voice, and positioning
→ Generates 6 slide concepts across proven carousel frameworks
→ Writes a detailed image prompt for each slide
→ Fires all 6 to ChatGPT Images 2.0 via FAL in parallel
→ Downloads finished slides + opens an HTML gallery

No Canva.
No designer back-and-forth.
No generic AI slop.

What you get:

-> Finished 1080x1350px slides ready to post directly to Instagram
-> Wavy color-blocked backgrounds, bold typography, product hero — all baked into the image
-> Brand-accurate colors and copy pulled from the live site automatically
-> A reusable pipeline — new brand, new folder, same 3-minute workflow

Built 100% in Claude Code.

I put together the full step-by-step playbook so you can build this yourself.

most people compare AI cost to free. wrong comparison.

1. Claude + Codex: $150/mo
2. junior dev: $8k/mo + 3 months to ramp
3. freelancer: $150/hr, 80% meetings
4. AI: works at 3am, no equity, ships weekends

you're not paying for tools. you're buying leverage.

[Layton Gott @Layton_Gott]

“AI is so expensive”

No, it really isn’t.

I burn $150: on Claude/Codex every month and ship what would’ve cost hiring someone $8k

Stop comparing it to free.

Compare it to the alternative.

[Paul Vu @PaulVuAI]

this is 80% right. the other 20%:

1. internal tools — underrated sweet spot
2. data scripts/scrapers — works if you review
3. API integrations — solid with a spec
4. CLI tools — surprisingly capable with Claude

the real limit isn't the domain. it's having no spec.

Vibe coding doesn't work well beyond web and app development

[Paul Vu @PaulVuAI]

@_MaxBlade Day 32 and still shipping. The consistency compounds — most people quit by week 2. Keep going, @_MaxBlade

[Paul Vu @PaulVuAI]

@MattPRD The Agent QA denominator is doing all the heavy lifting here. Most builders skip it and wonder why their agent hallucinates in prod. The formula is right — the weights are wrong.

[Paul Vu @PaulVuAI]

@willmcgugan The CSS tax is real. Claude nails 95% and then spends 5k tokens fighting border-radius. That last 5% is always faster to just hand-code. Still wouldn't trade vibe coding for anything.
