@nickbaumann_ Recording mp4 verification is such a smart move. Reading test logs is painful but watching a 30 second screen recording instantly tells you if the UI actually works. The trust gap in autonomous coding is real and visual proof closes it way faster than any test report.

We are dangerously close to putting Codex in autonomous loops where it picks up tickets, tests it's own changes via Playwright, and records and uploads verification mp4s to PRs. If you've never asked Codex to test your app, do try it!

@DrClownPhD Hugh Jackman fighting Death is honestly a better movie pitch than the original. The IP filters are getting aggressive though - tried generating some classic action scenes last week and got completely different actors too. At least the results are still entertaining.

Lmao I tried using Seedance 2.0 to make a fight scene with Chuck Norris destroying Death, but there are so many IP protections now that it even removed the name “Chuck Norris” from the dialogue. Even funnier, it didn’t use Chuck Norris, it used Hugh Jackman instead 🤣

@garrytan The Starship Enterprise analogy is perfect. Playwright as the hands, Claude Code as the brain - once it can reliably navigate real UIs and verify its own work, the loop closes. The gap right now is handling auth flows and dynamic content gracefully, but it is closing fast.

/plan-ceo-mode in GStack can do this "zoom out" trick for any thing your codebase already does. Soon my /browse skill will not just be just a Playwright wrapper but one where my Claude Code will be able to do real work for me. A new thing is emerging: I don't want to write apps anymore. I want the mega-control panel that doesn't hide things from me. I want the system prompt to be in front of me, not hidden or inaccessible. Claude Code is becoming the bridge of the Starship Enterprise for me. This, plus voice, and we are basically there. "Computer, order me a sandwich on DoorDash." [sandwich shows up]

@minchoi Sub-100ms first frame is wild. The real unlock here is interactive workflows - imagine adjusting prompts and seeing results in near real-time instead of waiting 2 min per iteration. That feedback loop changes everything for creators.

Waiting minutes for AI video generation is over. Runway's new model on NVIDIA Vera Rubin hits under 100ms to first frame. Minds are blown.
Runway@runwayml

A breakthrough in real-time video generation. As a research preview developed with @NVIDIA and shared at @NVIDIAGTC this week, we trained a new real-time video model running on Vera Rubin. HD videos generate instantly, with time-to-first-frame under 100ms. Unlocking an entirely new creative paradigm and bolstering the foundations of our General World Model, GWM-1. Real-time generation opens a fundamentally different design space for video models and world simulation. We're investing in co-designing our models alongside advances in hardware to keep pushing this frontier.

@tom_doerr The CDP integration looks solid. Using real Chrome instead of bundled Chromium makes a huge difference for sites with bot detection. Curious if it handles dynamic page mutations well - that has been the trickiest part in my experience with Playwright-based automation.

@gauthampai @jamonholmgren This is exactly the pattern I use. Playwright takes screenshots, CDP intercepts network responses, and the multimodal model decides what to do next based on the visual state. Way more robust than trying to parse DOM for dynamic SPAs.

@jamonholmgren That's right. For example, a multimodal model allows an agent to contextually steer a sub agent to extract specific pieces of information from a screenshot and this is common when you are using tools like Playwright.

@SlipperyGem The 3AM queue story is wild. Demand clearly outpaced what ByteDance expected. Curious if the copyright crackdown will push them to add better content filters before the global launch, or if they just delay indefinitely.

Hollywood has ruined everything. Just wonderful. SeeDance 2.0 still has huge lines in China too though. Went to an AI conference over the weekend and one of the speakers was complaining how he had to queue stuff up at like 3AM in the morning. SeeDance 2 is dying from success.
Kol Tregaskes@koltregaskes

ByteDance has suspended the global launch of Seedance 2.0, its video-generation AI model, after copyright disputes with major Hollywood studios and streaming platforms. The model launched in China last month but faced backlash for generating unauthorised copyrighted content, leading ByteDance to add stricter filters ahead of any international rollout.

@AIwithUsman The CDP compatibility is the smart move here - means you can drop it into existing Playwright/Puppeteer workflows without rewriting everything. Curious how it handles sites with heavy JS frameworks though. Memory gains alone make it worth trying for parallel scraping jobs.

🚨BREAKING: Someone built a headless browser from scratch not a Chrome fork and it runs 11x faster with 9x less memory. Lightpanda is the first browser built specifically for AI agents, scraping, and automation. And the benchmarks are wild. Here’s what makes it different: → Built entirely in Zig not a Chromium wrapper or fork → 11x faster execution than headless Chrome → 9x lower memory usage (207MB for Puppeteer vs almost nothing) → Full CDP support a drop-in replacement for Puppeteer and Playwright → Zero rendering overhead purpose-built for headless from day one → No persistent state, cookies, or sessions bleeding between agent tasks → MCP server support built in for Claude Code and Cursor Why it exists: the founders scraped millions of pages per day at their last company. They spent years fighting Chrome at scale so they started over from a blank page. The result? Developers say it could cut server costs dramatically. 12,000+ GitHub stars. Still in active development. It’s 100% free and open source.

Seedance 2.0 is absolutely insane with the physics! 🤯 Just look at those reflections and the blade motion. AI video is evolving way faster than my sleep schedule can handle tbh. Is Seedance your go-to now, or are you still loyal to Luma/Kling/Grok?

@corbtt The real unlock was using CDP with real Chrome instead of bundled browsers - bot detection drops to near zero. A smarter model that can handle flaky selectors saves more eng time than any framework improvement honestly.

GPT-4 era browser automation was interesting but functionally useless. With Opus 4.5 it finally got reliable enough to be useful for many background tasks. With GPT-5.4 (fast mode, low thinking) it's now almost as fast as I am.

@sachelik Selector fragility is real. I maintain Playwright scripts and every UI update means fixing locators. Vision-first is cool - how does Lumen handle visually similar elements like multiple Submit buttons on the same page?

Browser automation is fragile. Scripts break constantly and agents waste tokens getting stuck in loops. Today there are two options: Selector-based scripting like Playwright and Puppeteer: these require you to target specific DOM elements. First-generation browser agents: use natural language interfaces but still resolve instructions into selectors under the hood. Selector-based scripts can break every time the UI changes. You end up maintaining selectors instead of building features. First-gen agents inherit the same brittleness, especially when they misidentify the right element.

@garrytan Playwright CLI is honestly underrated for agent workflows. The real trick is using CDP to attach to an existing Chrome session - you get your real cookies, extensions, and zero bot detection. 100 lines of Python beats any MCP server for browser tasks.

MCP sucks honestly It eats too much context window and you have to toggle it on and off and the auth sucks I got sick of Claude in Chrome via MCP and vibe coded a CLI wrapper for Playwright tonight in 30 minutes only for my team to tell me Vercel already did it lmao But it worked 100x better and was like 100LOC as a CLI
Morgan@morganlinton

The cofounder and CTO of Perplexity, @denisyarats just said internally at Perplexity they’re moving away from MCPs and instead using APIs and CLIs 👀

Shipping code with AI tools but never experienced Cursor? I am giving one developer a 14-day Cursor Pro pass – this is not a lottery, it is a skill-based selection where your answer determines the winner. To enter, reply in 2–3 sentences with one specific way you would use Cursor Pro in the next 14 days. Tell me what you are building and why Cursor would accelerate your work. Only replies following this format qualify. I will select one person based on clarity, specificity, and fit – then send the private link directly. Entries are open until 14th March at 23:59 UTC. After that, I’ll review all eligible replies and notify the selected person within 48 hours. Already a Cursor user? You cannot redeem this yourself, but share it with a developer who deserves to level up.
