AI agents rely on a good harness. Faster inference gives a harness room to inspect results and recover sooner, while you steer the work. @MilksandMatcha breaks down the loop.
My thoughts on getting married young as someone who got married at 25 and is still very career driven 1. It is underratedly rewarding to find someone before you are successful. The number of times I have heard “series A then I’ll date” only to lead to “series B then I’ll date” six months later. I made a fraction of what I make now in an extremely IC position when I met Tyler and there is nothing better than knowing we got here together. 2. Two years ago, my husband went through and acquisition and joined NVIDIA. Half of the team had partners and or was married, the other half was single. We appreciate the fact we met pre-acq because there was never any question of whether someone is with you for the $$. Not that it would be a problem, but why have things spoil the relationship when it doesn’t need to. 3. Dating takes an absurd amount of time and emotional bandwidth and imagine if you just didn’t have to do that. 4. You can take a lot more risks with your career and personal life because you have another person to keep you emotionally and financially stable. If you take these big financial bets and they are successful then INCREDIBLE. If they are not successful, you will still be perfectly fine. 5. You pool your networks together and you know probably 50% more people (assuming you also have heavy overlap) and this is extremely helpful and makes me feel better when I stay at home on a Friday night 😅 6. In many ways the person you marry is an investment and the earlier you invest the better the outcomes! But more seriously, I optimized for a partner who I could grow a lot with in a very complimentary way. And this has worked out nicely.

A model and a killer founder. So proud of you @yusan_lin 🙌🙌
AI slop isn't just tacky and uninspired. It can get you sued. Generating fake AI faces that resemble real people, or using someone's likeness without permission, is creating new legal and reputational risks for brands. So we built @mirrormirror_ai as part of a16z @speedrun, a marketplace where brands can digitally book real models and creators to generate AI content using their likeness, with their permission. Brands browse and book identity-verified talent, agree on usage rights, and generate content within those terms. Every approved image comes with a signed license and embedded provenance. We're seeing brands produce lookbooks and campaign visuals up to 10x faster, with up to 90% cost savings. Meanwhile, models and creators can earn additional income from their digital likeness without having to show up for another shoot. Everyone is racing to make AI generation faster, cheaper, and more realistic. But there's still a huge missing piece: how do you license the rights to the people appearing in AI-generated content at scale? That's why I'm excited about what we're building. Not just another AI generator, but the licensing and rights infrastructure for AI-generated content.

Just your local sf “we have disaggregated inference at home couple” #iykyk#
two other notes 1. BTW, we are hiring 2. if you are all interested or intrigued in these types of roles, you must read
I have a lot of thoughts on the whole “it’s impossible to find someone technical who’s also good at creating content, has taste, and deeply understands the ai ecosystem (twitter)” In no particular order 1. I have seen many companies hire for this role too early. When I interviewed for this vague new media/ devrel/ DevX world before joining Cerebras, many very cool companies reached out but they had no clear product to market and no clear audience. What ends up happening is that there is no clear need or scope and this person is dumped to do everything because they lowkey can do everything. (Be warned) 2. Many of the best folks at this role did not start as GTM folks. The most common profile are folks who are engineers first, generally have CS degrees (although many are now self taught) and naturally found themselves really excited to be educators as well. Key word = educators. I had a CS degree from MIT, decided very early I did not want to be a software engineer because it was too monkey mill, and carved out a hybrid role for myself. 3. When thinking about who is exceptional at this role, it’s important to distinguish the person from the company. For example, if someone is at a top lab, how much of the viewership, followers, etc are from them or just natural company groupies. (This is not to say folks at oai, ant, etc are not extremely talented). 4. So! Now everyone thinks they can now be a creator because how good AI is. One of the main differentiators for engaging content is having a literal human face in your content versus obscene amounts of screen recordings and graphic animations. Thus everyone is trying to hire a face of a company and needs to hire faces of a company. 5. This is just a thought but there are very clearly AI companies built around their founder where the founder is the face and everyone at the company feels like it’s their job to just make the founder more famous. I will not name names. I appreciate smaller companies like @browserbase who seem to amplify the many voices in the company. 6. There are still a ridiculous amount of companies who do not realize the value of investing heavily in these types of folks. Perhaps they are scarred by the lack of impact of enterprise/ old school marketing. But these AI companies, when not doing well, react by firing and downsizing these technical GTM teams (wrong move buddy), you never hear about them again, and they spiral into oblivion. Don’t do this. 7. There are two types of companies who “get it”. The companies who just do, and the companies who have been burned by 5+ years of failing to get the company message out and are finally like oh shit. We need to hire these types of folks and do this type of thing.

Introducing Spork, an efficient post-training recipe which increases our solve-rate on chess puzzles by 100% when compared to our best GRPO setup. It uses a GRPO warmup, splits task-specific datasets further into partitions, trains specialists, and then uses multi-teacher on-policy distillation. Like a Spork, it leverages gains by simply consolidating specialists.

I quit a quant trading job at a top NYC firm right out of MIT to join Exa. I was the first employee (which means you do a little bit of everything!) and it’s actually how I discovered and found this hybrid GTM x engineering role that I really love today :) Huge congrats to @WilliamBryk and @jeffzwang. I hope you take some time to reminisce the good old days living and workout out of 533 page and how far you’ve come!!

Exa just passed $100m in annualized revenue. We've grown almost exactly 10x per year for 3 years. We now handle 2 billion requests a month from 200k+ teams. And it’s still so early: We predict agents will search 1000x more than humans by 2030. Agents don't search like humans. They write long, complex queries and want all the world's data, not just the web. We've spent 5 years building a search engine designed for them. We now serve personal agents, AI labs, coding agents, GTM agents, really any agent. Exa gives these agents access to 100s of billions of web documents and tons of proprietary data. Our customers are increasingly noticing that information is the bottleneck to agent performance. While the world seems close to perfect intelligence with models like Fable and Astra, we are very far from perfect information. To our small but legendary team, thank you for getting us here, from engineering to research to GTM to ops. To our customers, it is an honor to serve you. We have some exciting releases coming soon and can't wait to share them 🫡

Excited to see us intentionally build for long-context and fast decision making.
Introducing SubQ Snap, the first long-context decision model for real enterprise work. Snap is the only decision model or LLM where compute per token stays constant as context grows. • 384K tokens of multimodal context, 12x larger than Jev. • 61.7 on Decision Index v0.2.1 vs Jev’s 57.9, outperforming on 13 of 16 enterprise benchmarks. •Processes 100K tokens and returns a decision in under one second. •$0.05/MM input tokens. Output is free. Available today to anyone. The first 10,000 sign-ups get 100M free input tokens. We’ll likely hit capacity fast and will add users as we add compute. Compute offers welcome 🙂. Latency will be variable as we tune the platform to this new model and category of users. Model speeds are 80ms for minimal context, 250ms for 32k, 660ms for 100k, and 2.5 seconds for 384k. Visit:
