Excited to share some progress we’ve made! There are too many narrow, less capable tools out there. We don’t believe you need another AI assistant. That’s why we’re building an AI operating system. Meet the new Embra: 1/5
I thought GPT already supports parallel tool calling?
🚨 BREAKING: OpenAI is dropping GPT-5 next week! —1M token input window, 100k output tokens —MCP support, parallel tool calls —Dynamic short + long reasoning —Uses Code Interpreter and other tools Codenames are: o3-alpha > nectarine (GPT-5) > lobster (mini) > starfish (nano)
Anyone have a good open source looping browsing agent (a la operator/director) that uses stagehand?
The speed of software commoditization is breathtaking, truly. - AI now writes most software - Anyone can now write software - All big tech companies are building as much as they can, competing everywhere on everything - For every need, people will have 10s-100s of choices
Working with AI creates an entirely different type of flow state. I'm not sure precisely how to describe it yet, but it's definitely more elusive and more powerful. The weirdest part is that the AI has to be in flow as well... in that, it must have a low enough error rate.
Lure is showing that you can be a centrist-democrat in a highly liberal city and still get rewarded for pragmatism/realism over performative politics. People care most about clear competence. axios.com/local/san-fran…
The most solid argument that AIs are mostly pattern matchers instead of "true reasoners"... Claude 4 loves to say "building this will take 1-2 weeks, is it worth the effort?" And then it will crank out 95% of the code 1 shot in 10 minutes.
It's becoming clear in chatter circles but I haven't seen much posted on twitter yet. Coding models have now achieved a very clear breakthrough in accuracy over longer 5-10+ minute coding tasks (agent runtime). Wasn't true a month ago, and enables background agents to work!
Some youtuber should record themselves on a thru hike over 50 miles or so with some friends... outfitted entirely a roman soldiers. Show the ultralight folks who's boss.

This just might be the death of slack if it holds. An insane limit that neuters all automations and value add tools. This destroys slack as a platform.
The new @SlackHQ API rate limits are absolutely insane: For accessing messages, you can now only make 1 request per minute, with a maximum of 15 messages 🤯 And yes this applies to ALL apps, not just public ones. We can't build internal tools on our OWN data. @Benioff this is…
My favorite part about building agents is that you learn as you deploy/operationalize them. If you start narrow, you can ask an agent to help with planning. If it makes recommendations, you can now improve the prompt with that information. Big increase to our sales lift.
Starting in early August, Embra's AI agent consulting arm will have room for 1 more client. We help Series A / larger seed companies or agencies doing $1m+ in revenue optimize their sales/operational flows with AI agents. If you want to learn more, DMs are open.
We are considering throwing out our entire landing page site on webflow and just going with @boltdotnew instead for that part. Webflow was great for people editing content. But generating code is simply even easier now. And webflows UI blows. I don’t want to manage css in…
People talk mostly about the most intelligent models. But 80% of the workload for data-centric tasks happens with the lighter, dumber models. They are the unsung heroes.
If you think you're overpaying for Hubspot or Salesforce, I'd love to see if we have feature parity for the things you actually need. Starting to convert a couple customers away now, which is a first for us. I need more test data to figure out if I can scale this pitch up!
I do this with Embra. :) I have a type of document in my AI memory system called "Unorganized thoughts" When I create one of these documents, an agent runs, breaks the topics down, and maps thoughts to all relevant companies/people/projects. Btw this is intelligent chunking!
I want my thoughts to self-organize traditionally tools like obsidian/roam enable you to manually organize knowledge graph. i just have 1 big doc i should just dump stuff into a box, have it organized+saved, then search and explore when i need to
In your CRM, do you use deals or do you mostly have one deal per company/account?
So many great new additions to Embra I can't wait to show you.
