"First, we should be humble about human intelligence. It is extraordinary, but it is also recent, circumstantial, and shaped by an optimizer that was never trying to create the smartest possible being. Second, we should be humble about our ability to define what comes next. As optimization becomes cheaper and more powerful, choosing the objective becomes more consequential."

Best Edit Model is here by @ideogram_ai It's unfair there are two guys in particular look good in every outfit, including the duck suit.
Introducing Ideogram 4.5, the most precise edit model. With each edit, leading models add artifacts, pixel shifts, and color changes. Ideogram 4.5 eliminates artifact buildup, making multi-turn editing possible. Live in Ideogram, the API, and launch partners. Open weights soon.

Man is in his own league, no need for a list.
Is there a point in doing next year’s Midas List? Just give Martin a trophy and move on.

Speechless to this generational run. And an once-in-a-lifetime founding story. Congrats @martin_casado @drfeifei @BenMildenhall and the whole @theworldlabs team!!!
I don’t normally write these things. But this one hits a bit different. Nearly three years ago I told a16z I wanted to spend part time outside the firm helping @drfeifei start and build a frontier model company. And what followed were some of the most remarkable moments of my career. From being at the founding table. To watching the first git commits. Seeing the very early very rough results that hinted at something much greater. Contributing to the open source. Watching the creation of new model architectures that pushed the state of the art in multiple areas. I saw the team spin magic from nothing again and again. And I was very privileged to be within the walls. I’m very proud of what was accomplished, and am so excited for what lies ahead. So congratulations to AMD for entering into an agreement with the leading spatial intelligence frontier lab. And congratulations to the World Labs team on a partner that has the vision, ambition and leadership to be the top AI technology provider globally. Also congratulations to Dr. Su and Dr. Li. Two world class CEOs with a common vision. The both of you working together is unimaginably legendary. Arguably the smartest leaders in tech with the shared goal of building the world's leading AI capabilities. I know you both share an optimistic view of AIs ability to aid humanity. We need far more of that. As everyone knows. I’m World Lab’s biggest fan. And will remain so. Thanks to @drfeifei , @BenMildenhall , @jcjohnss and the entire team for letting me tag along. What a crazy fucking ride. You stood at the frontier, and moved it. And will continue to. Again, many congratulations to everyone involved. The future of AI will be so much brighter with this partnership. I can’t wait to see where it leads. Here’s to new worlds!

I'm so much more optimistic about the future. Back to the basics of engineering, but this time with so much power and intelligence. Excited about this path of AI!!
TypeSafe AI's Diogo Almeida with a16z's Ben Horowitz and Martin Casado on Jev, the model built to live inside software: Diogo's elevator pitch for Jev is a simple question - where is all the automation? AI is unbelievably smart, but outside of chatbots and coding agents, it hardly touches any real work. His diagnosis is the industry built models that generate text for humans to read, and software can't consume that output. Jev reads natural language and returns a choice from a set of options with a confidence level assigned to each, so developers can build programs that reason about intent and make probabilistic decisions rather than relying on human interpretation. TypeSafe's philosophy is "We build prod, not God." 0:50 "Where the f**k is all the automation?" 2:50 Jev vs. Claude Code and Codex 6:55 Jev is a classifier and classifiers are sick 7:40 Chat vs. code: is Jev a slider? 9:00 Diogo: From mathlete to Kaggle to OpenAI 12:20 "We build prod, not God" 15:55 Reliability over demos 16:55 2021 thoughts: RLHF is AGI? 20:45 Optimizing for the wrong use case 21:50 Is the real world too messy to automate? 25:00 Nobody expected the Jev launch 26:35 Three kinds of reliability 28:05 Good at syntax, bad at architecture 30:00 The inverse SaaSpocalypse 33:40 Why coding agents automate so little 36:05 Probabilistic programming returns 38:45 Jev as the UDP-to-TCP layer for AI 40:20 The 5 stages of grief for embedding AI 41:30 Utopia: AI that actually does what you mean YouTube: piped.video/Ut3LOjKNJaE @CompleteSkeptic @typesafeai @bhorowitz @martin_casado

A couple of things that make Eleven v4 special: - Extremely low latency (100 ms p50 TTFB for Turbo) - By far the best voice similarity - Outstanding quality (#1 on Artificial Analysis and on our own benchmarks) It achieves all of this while being extremely reliable. Eleven v4 uses our new post-training stack and a surprising recent research discovery that we hope will greatly accelerate our future model development. By the end of the year, we expect delivery of new compute that will increase our training capacity almost 10x. Very excited for what's ahead! Congratulations to the team!
Introducing Eleven v4 and Eleven v4 Turbo, our fastest and most emotive voice models yet. Ranked #1 by Artificial Analysis.

These are the BEST swag of the year. @fal NEVER disappoints when comes to creativity.
The tote bags at our conference received so much love! We worked so hard on this mini-capsule for GenMedia Conference so thank you all for the kind words. 😵😭 Nearly every element was made and produced from scratch. - shell fabric: custom dyed nylon fabric in light sage - cord: custom developed cord 8mm cord - inside snap - metal d rings - fal logo silver carabiners - heat transfer logo - double patch pockets - care labels Some say they can be turned inside out. Made at fal design lab / @HyunjungLee_ with so much attention to detail down to the care label designs / thank you to our production partners!

my take, both labs have miscalibrated their medium reasoning levels. opus 5.5 is too expensive for its performance, astra is better than it needs to be
How does "thinking harder" change how models perform on math proofs? We ran GPT-6 Astra, Opus 5, and Opus 5.5 on every reasoning level: low, medium, high, xhigh, and max on our benchmark, Proof Bench v1.1.

Jevon’s paradox at work!
Text classification in MotherDuck just got ~50x faster at ~1% of the cost. prompt_jev() is a SQL function powered by Jev, TypeSafe's new system one model. 100k rows: 40s, $0.50, frontier-LLM accuracy. The LLM took 32 min and $37. Read on: motherduck.com/blog/motherdu…

Packed house at the @fal GenMedia Conference! Incredible group of founders, studio heads, and creatives who are here to talk about real use cases of AI in media. Also some awesome hands-on demos, like a generative photo booth 👀

This is not the promise of AI. It should be an aid to one’s craft, not instead of it.
I am done with this shit. It is over. The state of engineering right now is horrible. It has been half a month since I started a new role at a big company. Nobody knows anything here. The specs, code, tests, PRDs, tickets, resolution of those tickets, reports, etc., everything is made by Claude Code. Nobody on my team likes this. They are being forced to ship as much as they can. I have heard multiple times from higher management that pushing code is not a bottleneck, so why are we slow? People are working 12 to 13 hours a day just to press enter. Nobody is reading anything. Humans in corporate are doing nothing on their own. Everyone, literally everyone, from an L1 to an L7 engineer here is doing the same thing. Talk to Claude. There is no sense of victory. Nobody is resolving bugs. In reality, nobody is thinking anymore. Everything is done by LLMs. It is so soul-sucking. I would not mind it, to be honest, if we were at least given the time to check out the code and see what is going where. But no, the goal is to just ship. No matter what happens.
