Terrific @TheAtlantic piece on archaeologists' and anthropologists' slowly dawning realization that now-submerged areas on the coastal shelf--swathes of land drowned when the glaciers melted--may be where much of our species' early history took place. (Link in reply)

Giving a talk on Diffusion augmented LLMs (Uno) @askalphaxiv Some new results include: > A newer version of Uno which beats DFlash2 > Scaling to 400B scale > Speeding up RL post-training ๐Ÿ“… Friday Nov 13 โฒ๏ธ 10-11am PT Zoom: luma.com/fli4wjlr
Making LLM inference up to 3x faster using discrete diffusion without sacrificing accuracy? Come join us for this AI4Science talk: Unlocking Lossless Speedups in LLMs via Discrete Diffusion. In this session, the author Subham Sahoo will introduce Uno, a new approach from IFM that combines autoregressive and diffusion modeling to accelerate LLM inference. While parallel generation methods often sacrifice accuracy for speed, Uno uses lightweight diffusion adapters to generate multiple tokens in parallel, then relies on the original model to verify them, preserving its output distribution without requiring a separate draft model. So not only is it 3x faster, it also outperforms top speculative decoding methods, with speedups even works at large batch sizes. If you're working or interested in LLM inferencing, this is the talk to check out. :microscope: AI4Science on alphaXiv :calendar_spiral: Friday November 13th 2026 ยท 10 AM PT :microphone2: Featuring Subham Sahoo :speech_balloon: Casual Talk + Open Discussion Check out the paper here: alphaxiv.org/abs/2609.04010 Sign up for the talk here: luma.com/fli4wjlr

I confess to some frustration when people give more weight to AI theories and models over what we see in the real world. Synthetic benchmarks (METR time horizon) and theoretical models ("ECI is exponential") don't match the best empirical data we have. The theories are off rather dramatically when compared to the real world. That real-world data is admittedly limited. We need more of it, with higher granularity, frequently updated. But in a conflict between your model and the best real world evidence that exists, choose the evidence. And press for more of that empirical data. Conversely, if you don't update your models based on that evidence, why should anyone have confidence in those models?
Replying to @ben_j_todd
That isn't what we see in the real world. Actual time horizons in both OpenAI and GDM are dramatically shorter. And at OpenAI don't seem to be rising exponentially. Empirical evidence differs from the models.

This reponse from Mitchell is from a dev commenting how it's easy for their team to move with rapid iterations because they don't need to be SOC compliant. Too many devs + CTOs fail to realize that "modern eng practices" and "compliance" are not mutually exclusive! AT ALL
Replying to @matthewmorek
We are [nearly] SOC2 compliant. We've been working for almost half a year with consultants and auditors to approve this workflow and we're really, really close. Established, legacy auditors too (not sketchy startups).

What happened last night regarding the impeachment vote on Pete Hegseth was deeply embarrassing. Eleven House Democrats missed the vote. If they had been there, Hegseth would be impeached right now. Iโ€™m not worried about impeachment itself. That will come in January. Iโ€™m worried about the message this sends to the American people only a week after a seismic mandate was handed to the Democratic Party to get shit done. I donโ€™t care why these Members were absent or if this was some lowkey procedural strategy. What I care about is the messaging, and at the moment, the narrative is: โ€œDemocrats said they want Hegseth gone, but canโ€™t be bothered to show up to vote for it.โ€ That is not good. All it would have taken is a simple message from House leaders: โ€œWe want Hegseth gone, but donโ€™t trust current GOP leadership on this matter. We look forward to holding him accountable in January with the new Congress.โ€ Dem leaders really need to get it together on messaging. Immediately.

A Tomb Guard from the U.S. Armyโ€™s 3rd Infantry Regiment, โ€œThe Old Guardโ€ was forced to verbally reprimand Secretary of Defense Pete Hegseth and a group of his senior advisers Wednesday after some in the group laughed and loudly talked in front of the Tomb of the Unknown Soldier at Arlington. Video of the incident, posted by CNN, shows Hegseth standing and taking photos in front of the tomb with his wife, Jennifer, chief of staff Ricky Buria, deputy chief of staff Patrick Weaver as well as senior adviser and deputy assistant Tami Radabaugh, following a ceremony at Arlington National Cemetery for Veterans Day.

How to turn slop into gold. Super concrete steps from awesome @poteto on making coding agents trustworthy: 1. Clean up the code your agents learn from. Your codebase is one of their biggest inputs. Agents copy whatever looks like an established pattern, including workarounds, deprecated code, and yesterdayโ€™s questionable decisions. Clean those up, or watch them reproduce. 2. Turn corrections into enforceable checks. Every time you correct an agent, ask: can this become a lint rule, a type constraint, a test, or a better API? Put the correction somewhere the system can enforce it. A growing AGENTS.md still requires the agent to follow every instruction. 3. Remove opportunities for predictable mistakes. Her team @SpaceXSI restricts Reactโ€™s useEffect to framework internals because agents repeatedly misuse it in product code. They also enforce import boundaries between application processes. These constraints eliminate whole categories of mistakes that would otherwise keep coming back in review. 4. Give agents a reliable way to run and inspect the product. Provide debugging tools, reusable CLIs, and a โ€œfeature mapโ€ describing the application from the userโ€™s perspective. Now โ€œthat thing in the left sidebarโ€ has a shared meaning, and each agent can reuse the tools for checking it. 5. Review evidence of behavior. Have agents produce screenshots, videos, and state diagrams. These help you check what the product actually does and how closely that matches your intent. A convincing explanation of a fix is easy to generate; seeing the fix work is considerably more useful. 6. Spend serious effort on verification. Her team uses runtime verification and is experimenting with property-based UI testing and formal methods, including TLA+ model checking. Lauren says most of her token usage goes toward verification. Agents make some previously expensive testing work much more practical. 7. Automate once that loop is reliable. Her team now has agents exercise new releases, find bugs, open fixes, and merge them automatically. Getting to that level of trust took her about six months of investing in the environment. The results she reports: 11,000 pull requests shipped by her team in a month, a revert rate around 0.5%, and improvements in startup, typing, and switching chats. And what about infamous โ€œsoftware factoryโ€? if your coding loop produces slop, automating it produces more slop, faster, with a larger token bill. Start by making good code the easiest thing for an agent to produce. Then scale it. As always, content at @aiDotEngineer is gold ๐Ÿ†

We've developed a way to bootstrap post-training from positive examples alone and show it works on arithmetic, molecular structures, and scientific writing. We've used the method to train a 235B LLM for writing indistinguishable from human writing. 1/5

3 of 4 - With our egress path being out the docking hatch which is submerged underwater, we have to partially flood the capsule by opening and removing the docking hatch. As you can imagine, this is not a comfortable feeling letting water into the space which in real-life would be your only breathable air (in this case the trainer is not a sealed vessel). Then we have to take our survival kits, life raft and medical kits โ€“ make sure the equipment and crew are tethered together so we donโ€™t get separated and then take a deep breath, drop out the bottom of our floating Orion, and swim up to our raft on the surface. Just another great day of training for @NASAArtemis III crew!

The coexistence of RSI with a fundamentally bottlenecky world will give rise to a late 2020s that feels like this: the rich strangeness of hyperfuture living alongside large swaths of unchanged or even regressing social practice, a temporal redshift all over your perception

So excited to see this work with brilliant @LiuQiawen (<- on the job market!) finally out!
Scientists spend their careers trying to understand the world, but a new study in Royal Society Open Science suggests they have surprisingly different ideas about what science itself is.ย  Former SFI Postdoctoral Researcher Marina Dubova (@dubova_marina) and Qiawen E. Liu found that scientists can disagree about the meaning and purpose of science even more than the general public does. santafe.edu/news-center/newsโ€ฆ

Despite everything, I don't think I've ever got as many supportive messages. I won't be able to respond all, because I'm deeply focused. So I just wanted to say I'm thankful for all the kindness in the world. Also, thanks for these who invested in us against the tides. I can't promise our approach will scale, there is a graveyard of talented people who tried and failed in the past, but, if there exists a system capable of reasoning without the drawbacks of gradient descent, we'll use every resource available to find it. Meanwhile, auto-research loops keep going. HVM5 is now shockingly fast; about 4x faster than HVM4, and it runs on CPUs and GPUs via Bend's parallel lets. It is beautiful so I must resist my own temptation to open source it, as it is a key component of our SAI research. We also made a lot of progress on Bend since Studio Vibi has merged with HOC, specially on the user-facing side. More on that later...
