I am building a team.

If you're really really really good at building stuff, design, filmmaking, writing, pushing the models to their limits, or just making people care about a product at mass, certainly reach out.

Let's collab + make stuff.

@FurqanR @thirdweb Thanks - definitely. Always down for it!

[Jake Loo @jake_loo]

I've stepped down from @thirdweb.

After 4+ years as co-founder and CTO, building this company from the ground up, scaling the team to 50+, shipping tools developers need to build onchain apps, it's been one of the most rewarding experiences of my career.

I got to work alongside some genuinely brilliant people across engineering, product, business, and marketing. The kind of people who challenged me, inspired me, and made me better at what I do. Lucky to have learned from every one of them, and especially grateful to have built this alongside @FurqanR an incredible co-founder and partner.

The crypto industry looks nothing like it did when we started. The use case has sharpened: disrupting financial rails. I'm excited to watch the team take thirdweb to the next level. I'll always be cheering from the sidelines.

At thirdweb, we built and deployed multiple AI agents across our product and org. I watched AI go from a nice-to-have to something that fundamentally changed how we worked. That experience shifted my thinking.

In early 2025, I only trusted AI with non-critical parts of the codebase. That has changed. Over the last couple of months, I've trusted it to build critical-path systems. It still demands proper system design, planning, and testing. But the gap between what AI can do and what we let it do is closing fast.

I don't think anything matters more than AI right now. Not as hype, but as a practical shift in how software gets built and used, how teams operate, how entire industries reorganize.

So I'm going all in.

Right now, i'm researching, experimenting, and building in AI. If you're working on something interesting, I'd love to hear about it -- let's connect!

@FarzaTV 🤠

[Jake Loo @jake_loo]

@Marfuenn thats the way

[Jake Loo @jake_loo]

software engineering is shifting from writing code to designing the world agents work in.
the real skill now is crafting the environment for the agents to thrive.
maybe it’s time to update the job title.

[Anthropic @AnthropicAI]

New Engineering blog: We tasked Opus 4.6 using agent teams to build a C compiler. Then we (mostly) walked away. Two weeks later, it worked on the Linux kernel.

Here's what it taught us about the future of autonomous software development.

it's consistent with what we found ~6 months ago.
switching to code execution tools reduces our agents latency significantly

New on the Anthropic Engineering blog: tips on how to build more efficient agents that handle more tools while using fewer tokens.

Code execution with the Model Context Protocol (MCP): https://t.co/PeStmufIkp

[Jake Loo @jake_loo]

@Basat1936 @thirdweb it's fixed now. it was an issue with bad token price data

[Jake Loo @jake_loo]

@cattybk @thirdweb it's been a wild journey together -- gonna miss the acre & sweetgreen days.
excited for what you'll be doing next!

[Joaquim @joenrv]

4x FASTER.

we now default to eip7702 execution for server wallets instead of erc4337.

sending to confirmation: 2 secs (~4x faster than 4337!).

as fast as a EOA tx, but with gas sponsorship, atomic batching and session keys support!

[Prithvish ⋅ d4mr @earth_ish]

we just open sourced engine-core

2 years 7 months of our learnings distilled into 25k lines of production Rust. this is the best thing I've ever built as an engineer.

our first open source rust repo at @thirdweb. let me tell you about my baby:

[thirdweb @thirdweb]

The Dead Internet Theory claims all online content will be AI generated - destroying the internet experience.

Blockchains will solve this problem.

Our Founder and CEO @FurqanR explains how. 👇

[Jake Loo @jake_loo]

@sharifshameem @FarzaTV exciting!

[Jake Loo @jake_loo]

@FarzaTV @sharifshameem bullish

[Jake Loo @jake_loo]

making ai multiplayer multiplies intelligence

it forces clear communication, and that will lead to better results

this will be the norm for how work gets done

[Sharif Shameem @sharifshameem]

We made Claude, but multiplayer.

For the first time (ever) -- you can collaborate with a model + others in the same exact chat.

Demo + available now:

This is so exciting - LLMs, but for the physical world

V-JEPA 2: real-world video in -> next action out
LLMs: text in -> next token out

Combining them is gonna be wild: LLMs as brains, V-JEPA as bodies.
Robotic agents that plan and act are almost here

[AI at Meta @AIatMeta]

Our vision is for AI that uses world models to adapt in new and dynamic environments and efficiently learn new skills.

We’re sharing V-JEPA 2, a new world model with state-of-the-art performance in visual understanding and prediction.

V-JEPA 2 is a 1.2 billion-parameter model, trained on video, that can enable zero-shot planning in robots—allowing them to plan and execute tasks in unfamiliar environments.

Learn more about V-JEPA 2 ➡️https://t.co/rYH5XOpfp0

As we continue working toward our goal of achieving advanced machine intelligence (AMI), we’re also releasing three new benchmarks for evaluating how well existing models can reason about the physical world from video.

@atbeme tips for becoming 1000x engineer

[Jake Loo @jake_loo]

As companies scale up, they ship more slowly. Why?

Coordination. It requires multiple people to ship.

An AI agent works across the stack. From reading code and product specs to producing content. Zero coordination needed

No more "finding time on your calendar". It just ships

[Furqan Rydhan @FurqanR]

The wildest AI takes are "it's not good enough yet" or "it can't do X well."

This completely ignores the exponential improvement curve we're on.

If you don't believe every aspect of digital work will reach human-level quality soon, you're setting yourself up for failure.

Agents are already handling tasks that required entire teams a few years ago. The building blocks for autonomous digital work is already here.

Most people aren't ready for how fast this will impact every company on the planet.

Jobs will transform, companies will become leaner, but we'll also see an explosion of new startups.

We're entering the greatest entrepreneurial opportunity in decades.

[Jake Loo @jake_loo]

@jmdagdelen @FurqanR @hthieblot it eliminates anything that needs cross-functional work:
- Technical content writer: agents that understand code, product specs, and the writing style guide
- Support: analyze, triage, and escalate

and most importantly, it takes less than 1 week to build these agents
