SurrealDB is #1 on the GDB-Engines Graph Database Movers list. We’re building the database for the next generation of applications, where connected, multi-model data is the default. Grateful to the community and team helping bring that future closer. gdb-engines.com/rankings/mov…

Why AI Can Now Make Discoveries - my conversation with @danintheory, Lead of the Foundations of Reinforcement Learning team at @OpenAI 00:00 Intro: AI's wild week in mathematics 01:21 What OpenAI's Foundations of RL team does 03:08 Dan's journey: from black holes and quantum gravity to frontier AI 07:04 Are AI systems becoming useful for real science 08:21 The AI math moment: Erdős, OpenAI, DeepMind, and Anthropic 08:52 Why the OpenAI result was an act of exploration 10:25 OpenAI vs. DeepMind: informal reasoning vs. formal proof 12:13 RL 101: learning by doing, not just watching 15:10 Why reinforcement learning works 15:58 How RL breaks: sparse feedback and long-horizon tasks 17:03 RLHF: how human feedback shaped early language models 18:48 Move 37, self-play, and the search for novel strategies 22:16 Explore vs. exploit in scientific discovery 24:49 Why RL may now be "the cake," not the cherry on top 25:46 Why RL started working with large language models 27:29 Is RL "sucking supervision through a straw"? 28:47 Why language may be the grounding layer for intelligence 31:46 A contrarian take on the Bitter Lesson 32:41 What test-time compute actually is 34:50 How RL gives models the ability to think 35:40 Verifiable rewards, math, coding, and the messy real world 38:00 What physics can teach us about AI 42:08 Is there a thermodynamics of AI? 43:08 From Erdős problems to Einstein-level AI 45:16 Is AI already doing original science? 45:51 How far are we from AI automating AI research 47:41 Why Dan is excited about the future of science

1/ Databases are entering a weird new era. Not because of AI hype. Because for the first time in decades, databases are being asked to behave less like storage engines… and more like memory systems. Today we shipped SurrealDB 3.1. And buried inside the release is something important: DiskANN.

Gradium TTS is particularly good at transferring all characteristics including reverb, bandwidth (e.g. phone speech), even typical podcast mic saturation on plosives ("p" sound). All samples in the video just generated from 10 samples without any processing.
I'm just as surprised nobody in AI voice tech has realized a voice needs background and environmental noise to sound realistic Even @ElevenLabs the leader in voice AI can not produce voice with background noise, or environment reverb sound AI voices are always going to sound non-passable as human if they don't have that And it's only me and this other guy even talking about it

Gathered 16 senior women engineering and product leaders around one cozy New York kitchen table! 🌸🍷 The wine and conversation flowed, a few themes we’re still thinking about: - The role of the 10x engineer; at what level do those gains actually accrue, and to whom? - Hiring for AI fluency vs judgment - Execution velocity is commoditized; gains are accruing to individuals vs whole companies. The bottlenecks have moved outside of eng. Is faster really better? - Blurred lines between roles; are we trading away healthy tensions between orgs in the name of efficiency? - Industry needs better frameworks for measuring AI ROI beyond token usage - Team incentives, core motivations, and building meaningful culture in a world moving this fast - Human connection and IRL mattering more than ever inside orgs cc @kathrynweinmann / @DaversaPartners 🤍
