A no-nonsense breakdown of the current AI agentic loop trend. This video explains what they are, when to avoid them to save your token budget, and the specific use cases where they actually deliver ROI.

[GREG ISENBERG @gregisenberg]

3 things I wanted to understand about "agentic loops":

1. What are they actually?
2. Is it hype?
3. What are the real use cases?

This is the most practical, clearly explained video on "agentic loops" on the internet (thx @Rasmic)

Claude Fable 5 just changed the AI game.

People are one-shotting games, 3D worlds, app builders and insane code optimizations. There's a major shift.

10 examples:

[Min Choi @minchoi]

Codex is not just for coding anymore.

People are using GPT-5.5 to run farms, build iOS apps, design in Figma, launch businesses and automate workflows.

10 wild use cases.

GitHub's scaling problem is real. Agents writing code faster than humans can review it.

That's not a funding round—that's a sovereign wealth fund bet...

[Anthropic @AnthropicAI]

We've raised $65 billion in Series H funding at a $965 billion post-money valuation, led by @AltimeterCap, Dragoneer, @Greenoaks, and @sequoia.

This investment will help us advance our research and expand our capacity to meet growing demand for Claude.

PMF doesn't mean the market's won. It means the API tax got cheap enough for builders to build. Now the real work starts.

Memory is now the bottleneck, not compute.

[Epoch AI @EpochAIResearch]

For frontier AI chips, memory is the largest and fastest-growing component cost.

High-bandwidth memory (HBM) has grown from 52% to 63% of total AI chip component spending between Q1 2024 and Q4 2025.

An 80-year-old conjecture in discrete geometry just fell to an AI model. First chess, then Go, now a problem humans couldn't crack. Math is next.

Video generation is quietly turning into world modeling.

[Google AI @GoogleAI]

By now, you've probably heard about Gemini Omni, our new model designed to create anything from any input, starting with video.

But... what's the big deal?

Let’s break it down 🧵👇

Stainless solves the problem nobody talks about until it's too late: SDKs rot faster than the APIs they wrap. Anthropic just bought a moat around developer experience.

The frontier labs are starting to look less like companies and more like Bell Labs.

[Andrej Karpathy @karpathy]

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

Two AI tools. One amazing latte art music video.

This is how powerful AI has become.

[Kōda @aimikoda]

GPT Image 2 + Seedance 2.0 = Latte Art 🎶

Using a few techniques I’ve shared recently, you can create musical animations like this one.

For this video, I used a Character Sheet + Storyboard + IPA.
Even though it skips a beat or two in places, that’s totally normal. I think it blended the musical tone with the artistic style instead of following every beat literally.

You can find the details below.
