"to me, it's not about the human in the loop, but the human at the center." i sat down with @Stefania_druga, staff research scientist @SakanaAILabs, at our @browserbase booth at @aiDotEngineer. after @MIT and @GoogleDeepMind, stefania recently joined sakana's recursive self-improvement (rsi) lab in tokyo to build self-improving AI for the next frontier. we got into: - catastrophic forgetting in day-long agent research runs, and how memory-first harnesses help - sovereign AI and open-weights: building on models you control instead of locking into one provider - why computer use still frustrates people even as models get smarter - the domains ripe for self-improving research agents: math, genomics, rare conditions - my fav moment at the end: what tasks are better left human, and what are we going to do as humans after everything is automated? with open frontier models arriving fast, @Stefania_druga's case for sovereign AI only gets stronger. loved this conversation. thanks for joining us at the @browserbase booth!

People often ask me: how are teams using @browserbase to power their workflows? I’ve met teams building things I never would’ve imagined a browser agent could do: - Receipts that file themselves, - Vendor research done in minutes, - Demos that close million-dollar deals, and so much more! If you're building an agent that needs to actually do things on the web, come talk to me!

"if i can interface with everything through my agent, why would i go to the dashboard?" i sat down with @sarahfim, mts at @composio, at the @browserbase @aiDotEngineer booth. fresh off her AIE talk "dashboards are dead," we got into: - why agent experience is the next wave and how to design for agents - personal agents as the main consumer of the internet - building and open-sourcing TrustClaw, a production-ready personal agents listen to our full conversation here:

for humans to align Al to their own individual weirdness and creative tension, these values must be encoded in the model weights @thinkymachines’ 975b parameter open source model is a huge step towards empowering humans with foundation models on an individual level i loved reading @miramurati’s essay on the importance of humanity in frontier models her essay makes the trade-off between centralization/autonomy and human involvement so clear and urgent, and is key to understanding why inkling’s mission is a much bigger deal than we think in order to keep our "human weirdness" alive, we must collectively solve the technical challenge of tailoring ai on an individual level thinkingmachines.ai/blog/the-futur…

"Every enterprise has realized they have to make their UX agentic, or the current one will die." We sat down with @KaranVaidya6, Co-Founder of @Composio, at our @aiDotEngineer booth. - Why 2026 is the year agents actually work - What actually counts as an "agentic harness" - Distilling 10M+ daily tool calls into reusable skills - How self-improvement becomes the next milestone
