this is the most important talk i've given in my time as a founder. in the next twelve months, we believe that every task that humans do online will be assisted by agent. watch this if you want to see the future that we're building for @browserbase

yesterday we hosted jev day at @browserbase as a fun way to hack on some internal ideas and invited anyone to join us they built some awesome stuff so I wanted to share the demos 🧵

it seems like agentic commerce is finally solved with stripe link. and we're excited to partner with stripe to enable all agents to transact online. your agent can now natively make payments on the web using link cli + browserbase. one shot prompt: docs.browserbase.com/integra…

we built blazing fast computer/browser use with Jev + @Stagehanddev. this task cost $0.001 and executed at near instant speed (in a remote browser btw) the loop: observe the page, send a11y tree as state + actions as questions, Jev decides the next action, then Stagehand executes it.
After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x cheaper (w/ output tokens free) • Frontier composable intelligence optimized for decisions AFAICT the shortest path to AI-based economic revolution

Hosting a panel this Friday: Pacing the Frontier? AI is moving fast. The question is how fast should it move, and what are we building toward? Joining me: @pk_iv, Browserbase @NaderLikeLadder, NVIDIA @FurqanR, Nebula @trq212, Anthropic Limited spots. RSVP below.

LangChain's CEO says they built their gateway a year too late, and it's still costing them. I sat down with Harrison Chase, Co-Founder & CEO of LangChain, to talk about what's changed since LangChain started as a side project in 2022, why sub-agents rarely work the way people expect, and why LangChain now runs its own hiring, content, and coding work through internal agents in Slack. 00:00 Why "I use agents for everything" is a red flag in an interview 01:21 How LangChain started as a fall 2022 side project 05:18 From LangSmith to LangGraph: rebuilding as the ground kept shifting 09:06 The gateway LangChain built a year too late 13:23 Code mode: why agents writing code beats human-style tools 19:04 Should the agent run inside the sandbox, or call it as a tool? 28:31 The agent identity problem: whose credentials does it use? 45:43 Running LangChain's own GTM, content, and coding agents in Slack 48:34 The AI slop problem, and why they built a Slack emoji for it The full pod is also available on YouTube, Apple Podcasts, or Spotify.

i built Scout, a small but mighty deep research agent that lives in slack. it uses @browserbase search and fetch + proxies to reach corners of the internet agents couldn't access before.

I trained a fly to use a browser. A simulated circuit built from part of the fly connectome makes the decisions. Stagehand turns them into browser actions. Check it out at flybrowser.lol

our conference on the state of the agentic web + computer use could not have been better timed! join us in SF on thursday for a glimpse into the near future: browserbase.com/navigate
It's Navigate week! Browserbase is hosting Navigate this Thursday (Sept 10) in SF. People are flying in from across the US to discuss the future of agents and computer use. Listen to speakers from @stripe, @vercel, @AnthropicAI, and more. Seats are running low. If you want to join the conversation on the future of agents, registration officially closes tomorrow.

We just made Astra's computer use 2.5x faster with Stagehand. Astra works by executing code against the a11y tree, we built a translator that turns Astra's playwright commands into @Stagehanddev. Astra chose to batch the entire logo into one command and one-shotted it.
GPT-6 Astra broke the internet with its ability to use blender and generate 3D worlds, all a byproduct of it's new computer use capabilities. I dove into the source code and wrote about the loop that makes Astra so good:

How does Astra’s computer use actually work?

Last week, OpenAI released GPT‑6 Astra, their most intelligent model yet. Despite it crushing agentic coding and alignment benchmarks, they chose to highlight one specific ability: computer use. The

we are now approaching the "second order problems" phase of agents browsing the web. ex: how do we prevent abuse? who is responsible for this agent's actions? what access should it have? thankfully, i believe these are all solvable problems. exciting times ahead!
