The Internet
It’s been incredible to see x402 go viral this week! For anyone new, welcome to the movement. I designed x402 to be the HTTP of money: a universally accepted, neutral, core primitive to help make the internet ready for the AI era. I can’t wait to see what people build 🛠️

I'm still in stealth, but I'm hiring! Location: SF preferred, but remote in North American time zones is possible for exceptional candidates. Open roles - Founding Engineer: build stuff - Founding Product Marketing Manager: grow stuff We offer generous salary, equity, health care, and the opportunity to work with smart and kind people on meaningful problems to help advance the state of agents. How to apply: Email jobs @ 5d.tech with: - LinkedIn / X / GitHub / Resume / Personal site / etc - A description of the thing you've built you're most proud of - Your current favorite product & why you like it - Your all time favorite website - A good meme

impressive result on JevBench
Replying to @marco_derossi
On JevBench, Sage1 scores better on accuracy than other System1 models, with a similar median latency. When multi-step reasoning is required, Sage has 93% accuracy vs. 71% for other System1 models. Sage is smart enough to know when to be fast and when to think step by step, covering both System1 and System2. When Sage activates reasoning, it takes on average 3X longer to decide.

The Office but it’s a hedge fund run by agents who can lie to each other At market close, an episode gets generated from whatever happened with @fal H3 Max was gonna open source it but they were up 3 days in a row so now nuking the game mechanics and giving them real money

The crypto x ai bears are missing the whole point. The bull case for x402: - digital goods (i.e., data) and services (i.e., SaaS) are often gated behind paywalls or at least a sign up - this adds friction to an agent using these as it goes after a goal - x402 makes everything permissionless and agent-discoverable. agents only need to buy what they’re using. - as agents start to easily discover x402 services, SaaS providers will be incentivized to add their services behind payment gateways to tap into agent distribution - this becomes a massive flywheel — a true permissionless network of everything in the digital world (and eventually will tap into meat space with robotics and meat proxies) - if we do this right it can create an autopilot agent economy that gives us more abundance than we could even imagine Permissionless commercialization + micropayments need crypto.
Might get cancelled for this but I’m very bearish on agentic micropayments.

The internet is so underrated. Theres no chance we would have ended up with AI without the open web.

What a debut for fal Research. Congrats team. Next task: accelerate all video models. DMs open. Be fast or be irrelevant.
Introducing H3 Max, new post-trained video model by fal Research. H3 Max ranks #1 for overall quality, prompt understanding, and aesthetics against leading video models, on both first-party and third-party independent evaluations while generating a 5-second 720p video under 3 seconds. H3 Max is 50% off for the next week, making it the highest quality, fastest and cheapest model for overall video generation tasks.

For the past two weeks, I've been working on a new visual identity for x402, which is an open standard for internet-native payments. I aimed to convey what x402 stands for: an HTTP status code that's finally been given a purpose: A way for AI agents (and anyone else) to pay natively over HTTP without filling forms or making accounts. Essentially, x402 is connecting two worlds that were separated until now. Relied heavily on animations to make the concepts easier to understand. All done thanks to @Figma motion + agent!
Visual direction for the new project I'm working on using @Figma motion.

Agents are like water, they’ll flow to whatever solution is easiest
Just had my first organic agentic x402 magic experience • Needed my agent to access a website for which I didn't have an account. • It discovered (on its own) Apify, which accessed that service on its behalf. Apify accepts x402 payments, which is what my agent then suggested • Agent set up its own wallet (it has never done a crypto tx before), gave me a deposit address on Base. I sent it some USDC (and no ETH) • Agent then connected to Apify on its own, arranged payment via x402, and got the data it needed, reporting it back to me. The whole sequence involved just 4-5 single sentence prompts from me. That was all pretty magic, but then I asked it this question. Agentic commerce on crypto rails is the future. agent was pi agent model was kimi-k3-fast-api on venice.ai/api

35M+ transactions have settled over x402. Until now, none of them touched a corporate ledger. As of today, Agents can now make payments via x402 on Ramp with attribution and audit trails built in. This lets Ramp customers: 1. Provision & fund agent wallets 2. Empower agents to buy via x402 on Solana 3. Use the ledgering and spend controls that finance teams expect out of the box Are you a builder who wants to be in our alpha? Reach out via DM or the link below 👇

x402 is inevitable. Every agent is going to need to pay for things. And there will be far more agents than humans.
x402 got written off way too fast and will become one of those things everyone will suddenly rediscover once the right products are built on top of it

@sapiom just raised a $35 million Series A from @dragonflyvc , @Accel , @AnthropicAI and others to help unlock the next trillion agents. The first thing we’re tackling is cost. To make that happen, we are launching three new products today at Sapiom.ai

@youdotcom is adding x402 support to our Web Search API, letting AI agents discover, purchase, and use fresh web data on demand without API keys, subscriptions, or human checkout flows. For trading agents, that means search can now be bought programmatically at the exact moment a decision needs to be made. 🧵

Of all the "manage many agents" tools i've tried @orca_build is definitely the best. @zeddotdev for editing code / pair programming with an agent for high precision things, Orca for swarming. github.com/stablyai/orca

Stacked diffs are now more useful than ever. Far easier to review LLM code if it’s broken into stacked diffs.
Look, better late than never to ship stacked PRs. But this feature was extremely useful 2015-2025 at most companies using it. Since ~Nov 2025 when AI models became more capable and write more and more of the code, stacked diffs have so much less relevance. GH feels years behind

fyi all @ChatGPT Codex tasks you start from @linear are default public & leak your internal repo + branch names. Doesn't seem to be a way to force them private.

Awesome write up from @fastly today - they are bringing x402 payments to the edge ⚡ fastly.com/blog/automated-pa… This new demo shows how Fastly Compute can enforce payment before a request ever reaches the origin, letting agents pay for APIs and digital resources automatically with @USDC on @Base. A powerful pattern for metered APIs, premium data, crawlers, and machine-to-machine services.
